📋 Clinical Stem — Bloody Diarrhoea with Urgency and Tenesmus
A patient presents with bloody diarrhoea, rectal urgency, and tenesmus, consistent with a first presentation or flare of ulcerative colitis.
“A 28-year-old male software engineer presents with a 6-week history of increasing bloody diarrhoea, opening his bowels 6–8 times per day including at night, rectal urgency, and crampy lower abdominal pain. He has lost 3 kg over 4 weeks. He has had a similar episode 2 years ago that resolved spontaneously, and was never formally investigated. He is anxious about cancer and worried the symptoms are affecting his ability to work.”
This stem applies to first presentations of UC and to flares of established UC. Adapt to: severity (mild/moderate/severe using Truelove-Witts), Montreal extent (proctitis/left-sided/extensive), comorbid anxiety, occupational impact, and the patient’s hidden agenda (cancer fear, medication reluctance, desire for dietary cure).
Scenario A — First Presentation, Moderate Severity 28-year-old with 6-week bloody diarrhoea ×6/day; worried about cancer; previous uninvestigated episode; needs diagnosis and urgent GI referral
Scenario B — Known UC, Mild Flare on Mesalazine 42-year-old with established UC (E2, on mesalazine 2.4g/day); 3-week increase in frequency and bleeding; last scope 2 years ago; GP to optimise treatment before GI review
Scenario C — Severe Acute Colitis 35-year-old with known UC presenting with bloody stools ≥6/day, fever, tachycardia, abdominal pain; requires same-day hospital admission — do not manage in primary care
Scenario D — UC with Extraintestinal Manifestations 38-year-old with known UC presenting with a painful red eye (anterior uveitis) and joint pain; extraintestinal manifestations may parallel or run independently of gut disease activity
Scenario E — UC and Pregnancy 30-year-old with established UC, currently 14 weeks pregnant, asking about safety of mesalazine in pregnancy; reassurance and obstetric co-management required
Key variables to adapt for Truelove-Witts severity (mild/moderate/severe), Montreal extent (E1/E2/E3), flare vs first presentation, extraintestinal features, pregnancy, cancer surveillance status, steroid use history and duration, medication adherence

History Taking — Open Question First · Targeted Questions · ICE · Psychosocial Context
collapse
Ulcerative colitis presents with bloody diarrhoea, rectal urgency, tenesmus, and lower abdominal cramps. The GP’s history task is to establish symptom severity (Truelove-Witts criteria), triage urgency, identify red flags for severe or complicated disease, and explore the psychosocial impact of a relapsing-remitting condition. Cancer fear is the most common hidden agenda. Always ask about nocturnal symptoms, weight loss, and extraintestinal manifestations which point to systemic disease activity.
🎓 Consultation opener — use existing information first
“I can see from your notes that you have been having problems with your bowels and some blood in your stools — that must have been really worrying. Could you tell me what has been happening in your own words?”
Reference the documented symptom; acknowledge the emotional impact of rectal bleeding before the clinical history; this scores in Relating to Others. Do not re-ask the duration if it is documented.
1A — Start with an open question: let the patient lead, then move to targeted questions
Question to askWhy it matters clinicallyChanges what?
🟩 OPEN QUESTION — always start here“Tell me about what has been happening with your bowels — what have you been experiencing and how has it been affecting you?” Allows the patient to describe the full symptom picture including severity, functional impact, and emotional state. UC patients are often distressed by blood and urgency — an open question allows this to surface naturally before systematic questions.Scores RO domain: patient-centred opening; allows natural ICE emergence including cancer fear and urgency impact on work DDxPsychosocialManagement
Stool frequency and blood volume“How many times are you opening your bowels each day and night? Is there always blood? How much — streaks, mixed, or predominantly blood?” Stool frequency and blood volume are the core Truelove-Witts severity criteria. <4 stools/day = mild; 4–6 = moderate; ≥6 = severe. Predominantly bloody stools indicate active mucosal inflammation and significantly raise the urgency of management.Nocturnal defaecation (waking from sleep to open bowels) indicates severe disease and requires same-day assessment or hospital referral DDxUrgencyManagement
Urgency and tenesmus“Do you have a feeling of urgency that you cannot defer? Do you feel like you still need to go even after you have been?” Urgency and tenesmus are hallmark features of UC (particularly proctitis and left-sided disease). Urgency causing incontinence significantly impairs quality of life and may indicate need for topical therapy. Tenesmus indicates rectal inflammation.Urgency and incontinence causing social avoidance → score high on IBD quality of life impairment; may need early referral DDxManagement
Systemic features — Truelove-Witts“Have you had a temperature or fever? Do you feel generally unwell? Any fast heartbeat or dizziness?” Truelove-Witts severe UC criteria include: stools ≥6/day with blood + ONE of: fever >37.8°C, HR >90 bpm, Hb <105 g/L, or ESR >30 mm/hr. These systemic features identify severe UC requiring same-day hospital admission — do not manage in primary care.Any one systemic feature alongside ≥6 bloody stools/day = hospital admission today; call 999 if haemodynamically compromised EmergencyUrgent
Abdominal pain and tenderness“Where is the pain? Is it crampy or constant? Does it feel different from before?” Lower left abdominal cramping is typical of UC. Constant severe pain, RIF tenderness, or generalised peritonism raises concern for toxic megacolon, perforation, or abscess — all surgical emergencies. Pain worse or changed in character in a known UC patient warrants same-day assessment.Sudden worsening of abdominal pain in known UC → perforation or toxic megacolon until proven otherwise; do not manage in primary care EmergencyDDx
Weight loss and appetite“Have you lost any weight without trying? How is your appetite?” Weight loss indicates significant systemic inflammation and nutritional compromise from active UC. It is also a red flag for colorectal cancer development in the context of longstanding UC. Weight loss alongside bloody diarrhoea mandates urgent investigation.Weight loss in a patient with longstanding UC → urgent colonoscopy to exclude CRC development within the colitis ReferralUrgent
Extraintestinal manifestations“Have you had any joint pains, skin rashes, mouth ulcers, or eye problems? Any back or hip pain?” Extraintestinal manifestations (EIMs) occur in 25–40% of IBD patients: arthropathy (peripheral joint disease and axial spondyloarthropathy), anterior uveitis, erythema nodosum, pyoderma gangrenosum, and primary sclerosing cholangitis (PSC). EIMs may precede, parallel, or be independent of gut disease activity.Uveitis requires same-day ophthalmology review — can cause permanent vision loss; PSC requires hepatology co-management ReferralManagement
Current medications and adherence“Are you on any medications for your bowel? Are you taking them regularly, and have you changed the dose?” Non-adherence to 5-ASA is the most common cause of UC flare. NSAIDs and antibiotics can trigger UC flares. Steroid use history is critical for management decisions (steroid-dependent UC requires immunomodulator stepping up).NSAID use in UC is associated with flare — switch to paracetamol; document every drug used including OTC medications ManagementDDx
Infection screen“Any recent travel abroad, antibiotics in the past 3 months, or new sexual contacts?” Infective colitis (Campylobacter, Salmonella, Clostridioides difficile, CMV) can trigger UC flares or mimic UC. C. difficile is common in IBD patients on immunosuppressants. Sexual infections (gonorrhoea, chlamydia) cause proctitis mimicking UC. Stool cultures are essential before steroid treatment.Never start steroids for a presumed UC flare without first sending stool cultures — immunosuppression of an infective colitis is dangerous DDxInvestigations
Cancer surveillance history“When did you last have a colonoscopy? Has anyone spoken to you about cancer screening?” UC is associated with a significantly increased CRC risk, particularly with extensive disease duration >8–10 years. Surveillance colonoscopy at risk-stratified intervals (1–5 years) is recommended by NICE NG151. Documenting last scope date is essential at every UC consultation.High-risk patients (pancolitis, PSC, family history of CRC, previous dysplasia) require annual colonoscopy ReferralManagement
Psychosocial and work impact“How is all of this affecting your daily life, your work, and your wellbeing? Are there things you are avoiding?” UC has major quality-of-life impact: urgency causes social avoidance, missed work, and impaired relationships. Anxiety and depression are prevalent in UC and worsen disease outcomes. Occupational impact (toilet access at work, shift work, client-facing roles) must be addressed directly.Workplace toilet access is a legal right under employment law for IBD patients — GP may need to write a supporting letter PsychosocialManagement

Safeguarding Considerations — Consider in Every Consultation

UC significantly impacts mental health, employment, and relationships. The relapsing-remitting nature of UC creates chronic uncertainty, and severe flares can cause financial hardship, relationship breakdown, and social isolation. Young adults are disproportionately affected during key life stages — education, career development, and relationship formation. A high index of suspicion for depression, anxiety, and self-neglect is appropriate in patients with frequent, severe, or refractory UC.
🏠 Domestic Abuse / Relationship Stress
  • UC’s impact on intimacy, urgency, and self-image can cause significant relationship strain and vulnerability to abuse
  • Partners who are unsupportive of IBD management (dismissing symptoms, undermining treatment) can impair disease control and mental health
  • Screen sensitively if patient presents repeatedly with poorly controlled UC despite apparently adequate treatment — home environment may be contributing
  • Use SAFE questions if domestic abuse is suspected; document findings and refer per safeguarding protocol
👴 Children and Young People with UC
  • UC in children and adolescents can cause faltering growth, delayed puberty, and significant school absence; refer to paediatric gastroenterology
  • Young people with UC may underreport symptoms due to embarrassment about bowel function, leading to delayed treatment escalation
  • School arrangements (toilet access, exam accommodations) require a GP letter and, where severe, a care plan
  • Mental health impact in adolescents with UC is significant — body image, social exclusion, and peer relationships are all affected
🧠 Mental Health and Self-Neglect
  • Depression and anxiety occur in 25–35% of UC patients and worsen disease outcomes through HPA axis activation and non-adherence
  • Self-neglect (stopping medications, missing review appointments) in a patient with UC may reflect a mental health crisis rather than non-compliance
  • Non-adherence to 5-ASA is the single most common cause of UC relapse — always explore the reason non-judgmentally before escalating treatment
  • Offer PHQ-9 and GAD-7 at every annual review; psychological therapy referral significantly improves UC outcomes
💊 Immunosuppression Safety
  • Azathioprine, biologics, and steroids cause significant immunosuppression; infection risk is substantially increased
  • Patients on immunosuppressants must be advised about infection risk and instructed to seek urgent assessment for fever or signs of sepsis
  • Varicella (chickenpox) exposure in an immunosuppressed UC patient requires urgent VZIG (within 10 days); document vaccination status before starting immunosuppressants
  • Live vaccines are contraindicated in immunosuppressed patients — check vaccination status before starting azathioprine or biologic therapy
If a safeguarding concern is identified: Follow your practice safeguarding policy. For children with UC: refer to paediatric gastroenterology and ensure school care plan is in place. For adults with self-neglect from mental health crisis: contact MH services, arrange same-day review if risk of harm. Document all discussions about immunosuppression safety and infection risk.

Smoking statusUC is paradoxically less common in smokers; smoking cessation is a recognised trigger for UC onset and flares (due to loss of nicotine’s colonic mucosal effects)Support smoking cessation for all other health reasons; counsel patients that stopping smoking may trigger or worsen UC; gastroenterologist should be aware if patient stops smoking
Stress and mental healthPsychological stress activates the HPA axis, worsens gut motility, and increases intestinal permeability — directly contributing to UC flaresPHQ-9/GAD-7; psychological therapy referral; stress management; gut-directed CBT reduces flare frequency in some studies
Diet and nutritionWhile no specific diet treats UC, nutritional status is often compromised during active disease; malnutrition increases surgical riskDietitian referral for nutritional assessment; ensure adequate protein and caloric intake during flares; avoid food restriction beyond clinical need
AlcoholAlcohol can trigger UC flares and irritates the gut mucosa; excessive alcohol also interacts with methotrexate and azathioprineAdvise reduction; alcohol is contraindicated with methotrexate; document units per week in the notes
1D — ICE: Ideas · Concerns · Expectations — in every consultation, not just SCA
💡 Why ICE matters in UC — not a tick-box exercise

UC patients carry multiple concurrent fears: cancer risk, colectomy, loss of control of bodily function, and medication side effects. These fears drive non-adherence (stopping immunosuppressants due to cancer concerns about azathioprine), delay in seeking help during flares, and dietary restriction that does not improve UC but impairs quality of life. Exploring ICE is therapeutically essential — naming the cancer concern and providing accurate risk data significantly improves patient engagement with surveillance and treatment adherence.

💭 Ideas
“What do you think is happening at the moment? Do you have any ideas about what might be causing this flare, or what you think we should do about it?”
UC patients often attribute flares to diet, stress, or specific foods without evidence. Understanding this attribution shapes patient education. Some patients believe UC is curable with diet alone — this misconception must be addressed to prevent delayed medical treatment.
😟 Concerns
“I ask all my patients with this condition: are you worried about cancer, or about what the future holds for you with this diagnosis? Or perhaps about the medications?”
The three dominant concerns in UC are: cancer risk (statistically real but manageable with surveillance), colectomy (feared but avoidable in most cases with good medical management), and medication side effects (particularly cancer concerns about azathioprine and biologics). All three must be named and addressed with accurate evidence.
🎯 Expectations
“What were you hoping would happen today — were you expecting a change in medications, a referral, or something else?”
Patients may expect immediate escalation (steroid prescription), gastroenterology referral, or alternatively reassurance that no change is needed. Mismatch between expectation and plan — without negotiation — leads to non-concordance and return consultations. Eliciting the expectation allows shared decision-making.
1E — Psychosocial context: the person behind the UC
🤝 UC as a Relapsing-Remitting Condition — The Chronic Illness Burden

UC is not a single acute illness — it is a lifelong relapsing-remitting condition that shapes the patient’s identity, decisions about work, relationships, family planning, and mental health. The GP’s role goes beyond acute flare management to addressing the cumulative burden of living with unpredictable, undignified, and distressing symptoms across the life course.

🏢 Work and Career Impact

UC urgency and unpredictable flares cause significant occupational impairment. Patients may limit career choices, avoid promotion, or reduce hours during active disease. Access to toilets at work is legally protected under the Equality Act 2010 for UC patients.

“Has this been affecting your work? Do you have reliable toilet access? I can write a supporting letter for your employer if that would help.”

Fit note and employer letter; occupational health referral; Equality Act 2010 — UC is a disability under UK law

🧠 Anxiety and Depression

25–35% of UC patients have comorbid anxiety or depression. The unpredictable nature of UC (not knowing when the next flare will happen) creates chronic anticipatory anxiety. Depression is associated with worse disease outcomes, higher hospitalisation rates, and non-adherence.

“Living with a condition like this that comes and goes unpredictably can take a real toll on your mood. How are you feeling in yourself?”

PHQ-9 and GAD-7 at every annual review; psychological therapy referral; antidepressants as appropriate (avoid NSAIDs)

👥 Relationships and Intimacy

UC affects intimate relationships through urgency, abdominal pain, body image concerns, and treatment side effects. Disclosure to partners, embarrassment about symptoms, and reduced sexual function during flares are common but rarely discussed in clinical consultations.

“Has the condition been affecting your personal relationships? I ask because this is something many people with UC find difficult to talk about, but it is important.”

Validate the impact without probing intrusively; refer to IBD nurse specialist for psychosexual support discussions

💐 Family Planning and Pregnancy

UC and its treatments have complex implications for fertility and pregnancy. Methotrexate is absolutely contraindicated in pregnancy and for 6 months before conception in both men and women. Many patients with UC voluntarily reduce family size due to disease-related concerns that are often based on inaccurate information.

“Are you thinking about starting or expanding your family? The timing and the medications you are on are important considerations — I want to make sure we plan that carefully.”

Mesalazine and azathioprine: generally safe in pregnancy under specialist guidance; methotrexate: absolutely contraindicated

🏋 Diet, Exercise, and Lifestyle

Many UC patients develop extreme dietary restriction, cutting entire food groups based on perceived triggers without evidence. Contrary to IBS, there is no strong evidence for specific dietary modifications in UC remission. Dietary restriction can cause malnutrition without improving disease.

“Have you been restricting your diet? I want to make sure you are eating enough — particularly during a flare, when nutrition is really important for recovery.”

Dietitian referral for nutritional assessment; no evidence for specific exclusion diets in UC; adequate protein and caloric intake essential

🚪 Fear of Colectomy and Cancer

Fear of colectomy and fear of cancer are the dominant long-term fears in UC. These fears drive both over-medicating (requesting biologics pre-emptively) and under-seeking (avoiding surveillance colonoscopy out of fear of bad news). Both fears must be addressed with accurate, evidence-based data at the GP level.

“Are you worried about the long-term picture — particularly about the cancer risk or the chance of needing an operation? I can give you some specific numbers that may help.”

Cancer risk is real but manageable with surveillance; colectomy rates are declining with biologics; address both fears with specific evidence, not vague reassurance

Triage Engine — Emergency · Urgent · Routine
collapse
The triage decision in UC pivots on Truelove-Witts severity criteria. Severe UC is a medical emergency requiring same-day hospital admission for IV corticosteroids, thromboprophylaxis, nutritional support, and surgical risk assessment. Moderate UC requires urgent gastroenterology review within 1–2 weeks. Mild UC can be managed in primary care with optimisation of 5-ASA. Never start systemic steroids without first excluding infective colitis.

Do I Need This Examination?
collapse
Examination in UC establishes systemic severity, excludes surgical complications, and identifies extraintestinal manifestations. The key findings are: pulse rate and temperature (systemic severity), abdominal tenderness and distension (toxic megacolon), and skin, joint, and eye findings (EIMs). Never attempt colonoscopy in suspected severe UC or toxic megacolon in the community setting.
ExaminationWhy it mattersWhat finding changes managementChanges management?
Pulse and temperature (Truelove-Witts)HR >90 bpm and fever >37.8°C are Truelove-Witts criteria for severe UC. Even one systemic feature alongside ≥6 bloody stools mandates hospital admission.Tachycardia in the consulting room = measure BP, check for postural drop (fluid depletion)HR >90 or fever → severe UC criteria met → hospital admission; do not manage in primary careYES — changes triage immediately
Abdominal examination — distension and tendernessAbdominal distension in a UC patient may indicate toxic megacolon (colonic dilatation >6cm). Peritonism (guarding, rebound) indicates perforation. Both are surgical emergencies requiring 999. Mild diffuse tenderness in the left iliac fossa is typical of active colitis.Tympanic percussion over a distended abdomen suggests gas-filled dilated colon — toxic megacolon until X-ray excludesDistension + tenderness → arrange plain X-ray urgently or admit; peritonism → 999YES — may indicate surgical emergency
General inspection — pallor, nutrition, hydrationPallor indicates anaemia (Truelove-Witts criterion: Hb <105 g/L = severe). Signs of dehydration (dry mucous membranes, reduced skin turgor, tachycardia) indicate need for IV fluid resuscitation in hospital.Visibly malnourished UC patient → dietitian input and nutritional support are urgent prioritiesClinical anaemia or dehydration → expedite hospital admission; FBC urgentlyYES — if anaemia or dehydration present
Eye examination — conjunctival injection, ciliary flush, photophobiaAnterior uveitis presents with red eye, ciliary flush (perilimbal injection), photophobia, and visual blurring. It is a sight-threatening emergency requiring same-day ophthalmology. Episcleritis (bright red, nodular injection) is less urgent but requires specialist review.Never attribute red eye in a UC patient to simple conjunctivitis without excluding uveitis — the consequences of missing uveitis are severeCiliary flush or photophobia → same-day ophthalmology; episcleritis → urgent ophthalmologyYES — sight-threatening emergency
Joint examination — peripheral and axialPeripheral arthropathy (colitic arthritis) parallels gut disease activity and may improve with UC treatment. Axial spondyloarthropathy (sacroiliitis, ankylosing spondylitis) runs independently of gut activity and requires separate rheumatology management.Axial joint symptoms require rheumatology co-management; do not assume they will respond to UC treatment alonePeripheral arthropathy → treat underlying UC; axial disease → rheumatology co-managementContext — if joint symptoms present
Skin examination — erythema nodosum, pyoderma gangrenosumErythema nodosum (painful red nodules on shins) is the most common skin EIM and parallels disease activity. Pyoderma gangrenosum (deep, necrotic ulcers, usually on legs) is less common, more severe, and runs independently of gut activity — requires specialist dermatology and often systemic treatment.Pyoderma gangrenosum is a diagnosis of exclusion; debridement worsens it (pathergy) — refer to dermatology before any wound treatmentPyoderma gangrenosum → urgent dermatology referral; do not debride; erythema nodosum → treat underlying UCYES — pyoderma requires urgent specialist input
Mouth — aphthous ulcersRecurrent aphthous ulcers occur in UC and parallel disease activity. They indicate active systemic inflammatory disease and may respond to UC treatment optimisation. Distinction from other causes of oral ulceration is important.Oral ulcers + bloody diarrhoea → UC EIM; consider if Crohn’s disease (transmural) is the correct diagnosisAphthous ulcers + diarrhoea → confirm IBD diagnosis; consider Crohn’s vs UC distinctionContext — supports IBD diagnosis
Blood pressure (postural) and fluid assessmentPostural hypotension (>20mmHg systolic drop on standing) indicates significant dehydration from high-volume diarrhoea. This finding, combined with tachycardia, mandates hospital admission for IV fluid resuscitation and monitoring.Postural drop + bloody diarrhoea ≥6/day = direct hospital admission pathway; do not send home with oral rehydrationPostural hypotension + tachycardia → hospital admission for IV fluids and monitoringYES — haemodynamic instability requires hospital

Step 4
Do I Need This Investigation?
collapse
Investigation in UC serves three purposes: confirming severity (Truelove-Witts blood criteria), excluding infective colitis before steroids, and monitoring disease activity and treatment toxicity. Stool cultures and C. difficile toxin must always be sent before systemic steroids are started. Colonoscopy (the definitive investigation) should be arranged urgently for first presentations but is contraindicated in acute severe UC (perforation risk).
InvestigationClinical question it answersWhat result changes management?
FBC (Full Blood Count)Is there anaemia meeting Truelove-Witts severe criterion (Hb <105 g/L)? Is there leucocytosis (active inflammation or infection)? Thrombocytosis (reactive in active IBD)? Neutrophilia (bacterial infection or steroid effect)?Hb <105 → severe UC criterion met → hospital admission · Hb <80 → consider transfusion · WBC >15 → exclude infection before steroids
CRP and ESRESR >30 mm/hr is a Truelove-Witts severe criterion. CRP is a better real-time marker of disease activity — CRP >45 at day 3 of IV steroids predicts 85% need for colectomy (Oxford Criteria).ESR >30 → severe criterion; CRP persistently high on IV steroids → urgent surgical and gastroenterology review
Faecal calprotectinIs there significant intestinal inflammation? Calprotectin >200 μg/g indicates active IBD. Useful to distinguish IBD flare from IBS-type symptoms in a patient with known UC. Cannot distinguish UC from Crohn’s.Calprotectin <50: IBD unlikely; symptoms likely IBS-type → avoid empirical steroids · >200: active IBD; escalate management and contact IBD team
Stool cultures (M/C/S) and C. difficile toxin — MANDATORY before steroidsInfective colitis (Campylobacter, Salmonella, Shigella, CMV) and C. difficile can trigger or mimic UC flares. Steroids during infective colitis are dangerous. C. difficile in UC patients on immunosuppressants has high morbidity.Positive culture → treat specific infection before steroids; C. difficile positive → metronidazole or vancomycin; do NOT start steroids; urgent GI advice
Electrolytes (U&E), LFTs, and albuminHypokalaemia and hyponatraemia indicate significant dehydration and systemic illness requiring IV correction. Hypoalbuminaemia (<35 g/L) indicates severe systemic inflammation and predicts poor response to medical treatment. LFTs may indicate PSC.Electrolyte abnormalities → hospital admission for IV correction; hypoalbuminaemia → urgent GI review; raised LFTs → check for PSC
AXR (Abdominal plain X-ray) if toxic megacolon suspectedToxic megacolon: transverse colon diameter >6cm with loss of haustra on AXR, with systemic toxicity. This is a radiological emergency requiring urgent surgical assessment. Do NOT arrange in primary care — arrange in hospital.Transverse colon >6cm → toxic megacolon confirmed → surgical emergency; 999 if not already in hospital
TPMT enzyme testing (before starting azathioprine)Thiopurine methyltransferase (TPMT) deficiency causes azathioprine to accumulate toxic metabolites, causing severe myelosuppression. Absent TPMT activity = contraindication to standard dose; reduced activity = lower starting dose required.TPMT absent → do NOT use azathioprine; discuss with gastroenterology · TPMT low → start at 50% dose; close monitoring · Normal TPMT → standard dose (2–2.5 mg/kg)
Colonoscopy with biopsy — first presentationDefinitive diagnosis of UC requires histology. Extent (Montreal classification E1/E2/E3) determines treatment choice. Distinguishes UC from Crohn’s disease (critical for treatment decisions) and from other causes of colitis.E1 proctitis → topical 5-ASA suppository first-line · E2 left-sided → oral + topical 5-ASA · E3 extensive/pancolitis → oral 5-ASA at highest dose; earlier immunomodulator threshold
FBC, LFTs (3-monthly monitoring on azathioprine)Azathioprine causes myelosuppression and hepatotoxicity in a proportion of patients. Regular blood monitoring is mandatory to detect these side effects before they become life-threatening.WBC <3.5 or neutrophils <1.5 → hold azathioprine; urgent gastroenterology advice · ALT >3× ULN → hold; re-challenge with lower dose under specialist guidance

Step 5
Reaching a Diagnosis & DDx — Explained in Plain Language
collapse
UC is diagnosed by a combination of clinical history, endoscopic appearance (continuous mucosal inflammation from the rectum, extending proximally), and histology (crypt distortion, goblet cell depletion, and mucosal inflammation). The GP’s diagnostic role is to suspect UC, exclude infective and other causes, arrange urgent GI referral for histological confirmation, and explain the diagnosis clearly to the patient. The Montreal classification guides treatment choices.
🗣️ Explaining the Diagnosis in Plain Language — say something like this

“What you have is called ulcerative colitis — UC for short. It is a condition where the immune system attacks the lining of the large bowel, causing inflammation, ulcers, and bleeding. Unlike Crohn’s disease, which can affect any part of the gut, UC always starts in the rectum — the very end of the bowel — and can spread upwards. It is a long-term condition that tends to come and go — you will have flares when symptoms are active, and then periods of remission where you feel completely normal. It is not caused by anything you ate or did, and it is not contagious. The good news is that most people with UC lead completely normal lives with the right treatment. The key is to get the inflammation under control and then keep it under control with maintenance medication.”

💬 Addressing the patient’s own explanation

“I thought I just had IBS — can IBS cause bleeding?”
“IBS is a completely different condition to UC — IBS does not cause bleeding, and it does not cause the kind of inflammation we are seeing. The blood in your stools tells us there is active inflammation in the bowel, which is what we need to investigate and treat. IBS is a diagnosis we can make if everything else comes back normal, but bleeding means we need to be sure.”

“Is this going to turn into cancer? My father had bowel cancer.”
“This is one of the most important things I want to address. Yes, there is a higher risk of bowel cancer with UC — particularly if you have had the condition for a long time and it affects a large part of the bowel. But with the right treatment and regular surveillance colonoscopies, this risk is very much reduced to close to the general population risk. We will set up a surveillance programme specifically for you.”

A — Confirmed by Endoscopy + Histology
Requires GI biopsy

Ulcerative Colitis (UC)

Continuous mucosal inflammation from rectum, extending proximally. Histology: crypt distortion, goblet cell depletion, basal plasmacytosis. Classified by Montreal extent: E1 proctitis, E2 left-sided, E3 extensive.

Proctitis (E1)

Inflammation confined to the rectum (<15cm from anus). Managed primarily with topical therapy (suppositories). Associated with tenesmus and urgency disproportionate to stool frequency.

B — Differentiate Actively (important DDx)
Requires exclusion

Crohn’s Disease

Transmural, skip lesions, can affect any part of the GI tract, perianal involvement, granulomas on histology. Can mimic UC in the colon (Crohn’s colitis). Treatment differs significantly (methotrexate is used; 5-ASA evidence less strong).

Infective Colitis

Campylobacter, Salmonella, Shigella, CMV, C. difficile, amoeba. Acute onset, travel history, recent antibiotics. Stool cultures distinguish; never start steroids before exclusion.

Microscopic Colitis

Normal endoscopy but abnormal histology; watery non-bloody diarrhoea; predominantly middle-aged women; NSAIDs, PPIs, and SSRIs associated; managed with budesonide.

Ischaemic Colitis

Older patients with vascular risk factors; sudden onset, left-sided abdominal pain; watershed area of splenic flexure most affected; requires CT angiography.

C — Complications — Act Urgently
Emergency management

Toxic Megacolon

Colonic dilatation >6cm with systemic toxicity; most feared acute complication; perforation risk; requires immediate surgical assessment and IV corticosteroids. Do NOT attempt colonoscopy.

Colorectal Cancer in UC

Risk: E3 pancolitis >10 years; cumulative 5–8× general population risk; dramatically reduced with surveillance colonoscopy and 5-ASA chemoprevention. 2WW referral if suspected.

Fulminant Colitis / Perforation

Peritoneal signs + systemically unwell; perforation can occur without preceding toxic megacolon; 999; IV antibiotics + surgical assessment; emergency colectomy may be required.

Step 6
If Referral Is Needed — What the GP Does Before & During
collapse
UC management is a partnership between GP and gastroenterology. The GP manages mild flares, prescribes and monitors maintenance therapy, arranges surveillance colonoscopies, and coordinates care. The IBD nurse specialist is the first point of contact for flares in established patients. Gastroenterology manages treatment escalation (immunomodulators, biologics), and surgery for refractory disease.
ConditionUrgencyWhat GP does before referralWhat GP must NOT do
Severe acute UC (Truelove-Witts severe) Same day — admit Send stool cultures and C. difficile toxin; arrange blood tests (FBC, CRP, U&E, albumin, LFTs); do not give oral steroids; arrange direct hospital admission via GI on-call or A&E; IV access if available Never manage severe UC in primary care; never start steroids before C. difficile excluded; never arrange colonoscopy in acute severe UC
First presentation of probable UC (bloody diarrhoea >2 weeks) Urgent GI (1–2 weeks) Send stool cultures, C. difficile, calprotectin, FBC, CRP, LFTs; document symptom duration, frequency, blood; do not diagnose UC without histology; do not start steroids or 5-ASA before biopsy confirms diagnosis in a first presentation Do not label as IBS without investigation; do not delay referral; do not start mesalazine before UC is histologically confirmed (may mask Crohn’s)
Moderate UC flare in established patient IBD nurse same day; GI within 2 weeks Contact IBD nurse specialist by phone; check adherence to current therapy; send stool cultures; start oral prednisolone 40mg OD if infection excluded and IBD nurse/GI agrees; reduce dose by 5mg/week from week 2 Do not start steroids before stool cultures; do not prescribe prednisolone >8 weeks without specialist review; do not continue steroids if no response at 2 weeks
Steroid-dependent or steroid-refractory UC Urgent GI (2–4 weeks) Document steroid courses (frequency, duration, dose); check TPMT before specialist appointment; optimise 5-ASA adherence; discuss azathioprine/6-MP initiation with GI; do not initiate immunomodulators without specialist input Do not start azathioprine without TPMT testing and specialist confirmation; do not continue steroid courses >2 per year without step-up discussion
Cancer surveillance — overdue or high risk Routine GI/Endoscopy Calculate years since UC diagnosis and extent; stratify risk (high: PSC, previous dysplasia, family history of CRC; intermediate: E3 >8 years; low: E1 or E2 <8 years); refer for colonoscopy at appropriate interval Do not miss surveillance colonoscopies; do not rely on calprotectin alone for cancer surveillance; do not defer surveillance indefinitely in high-risk patients
Acute uveitis or pyoderma gangrenosum Same-day ophthalmology (uveitis); urgent dermatology (PG) Uveitis: same-day ophthalmology — do not start topical OTC eye drops; PG: do not debride or apply topical antibiotics (pathergy risk); refer to dermatology urgently; continue UC management in parallel Never treat suspected uveitis with simple conjunctivitis drops; never debride pyoderma gangrenosum (causes pathergy — worsens the lesion severely)
UC in pregnancy Obstetric + GI co-management Continue mesalazine (safe in pregnancy); continue azathioprine if high disease risk (discuss with specialist); arrange combined GI-obstetric clinic; ensure folic acid 5mg OD; check medications for safety profile Never stop mesalazine in pregnancy without specialist advice; methotrexate is absolutely contraindicated; do not use high-dose steroids in the first trimester without specialist input

Management — Expectation · Goals · Lifestyle · Drug Selector · Drug Cards · Psychosocial · Follow-Up · Safety-Netting
collapse
UC management follows a treat-to-target strategy aiming for clinical remission, mucosal healing, and prevention of complications. The treatment ladder escalates from 5-ASA (first-line) to corticosteroids (acute flares) to immunomodulators (azathioprine/6-MP for maintenance) to biologics (infliximab/vedolizumab, specialist-initiated). Surgery (colectomy) is considered for medically refractory disease and is curative. The GP’s primary roles are: maintaining 5-ASA adherence, monitoring azathioprine, recognising flares, arranging surveillance, and supporting the patient’s quality of life.
7A — Address the patient’s expectation first: validate → explain → negotiate
🤝
Common expectation: “I want to control this with diet, not medication” or “Can I stop the medication when I feel better?”
1
Validate — the desire to manage naturally or stop medication

Many patients with UC want to manage the condition with diet alone or want to stop maintenance medications when they feel well. Both are understandable responses, but both lead to higher relapse rates and disease progression. Acknowledging the desire before explaining the evidence maintains the therapeutic relationship.

“I completely understand why you would want to manage this without long-term medication — nobody wants to take tablets indefinitely. Let me explain why the medicine is important even when you feel well.”
2
Explain — why maintenance therapy matters even in remission

5-ASA (mesalazine) reduces the risk of relapse by 40–50% and has a documented chemoprevention effect against CRC in UC. Stopping maintenance therapy significantly increases the relapse rate and CRC risk. The medication needs to be taken continuously, not just during flares.

“The mesalazine is not just treating your symptoms — it is actively protecting the bowel lining and reducing the long-term cancer risk. Even when you feel completely well, the microscopic inflammation can still be there. That is why it needs to be taken every day, indefinitely.”
3
Negotiate — acknowledge lifestyle changes that genuinely help

While no specific diet treats UC, there is good evidence for not smoking, reducing stress, and maintaining good nutrition. Acknowledging these genuine lifestyle contributions respects the patient’s agency and improves engagement with the treatment plan.

“The lifestyle changes you are making — managing stress, not smoking, eating well — do genuinely help. But they work alongside the medication, not instead of it. Let’s agree on a plan that combines both.”
7B — Why treatment matters: goals tailored to this patient
Treatment targets (treat-to-target)
Clinical remission — <3 stools/day, no blood, no urgency Mucosal healing on colonoscopy (Mayo score 0–1) tTG-IgA not applicable; calprotectin <50 in remission Normal CRP and FBC; albumin >35 g/L No steroid use >8 weeks/year; avoid long-term steroid dependence Prevent CRC — surveillance colonoscopy at risk-stratified intervals Return to full work, social, and recreational functioning No hospitalisation; disease managed in primary care and IBD clinic
Motivational language — tailored to the patient
“Taking your mesalazine every day, even when you feel completely well, reduces your chance of a flare by about half. That means fewer hospital admissions, fewer steroid courses, and a lower cancer risk over time.”
“The goal is for you to be able to work, travel, have a family, and live your life without UC constantly interrupting. With the right treatment, most people achieve exactly that.”
7C — Non-medication management: evidence-based lifestyle interventions
🚫
Smoking Cessation
Absolute priority for general health; caution re UC onset
The UC paradox

Nicotine has a protective mucosal effect in UC — smokers have lower UC incidence. However, smoking cessation is one of the most common triggers for a UC flare (the “paradox of cessation”). Stopping smoking is still strongly recommended for overall health.

What to advise

Strongly recommend smoking cessation for cardiovascular and cancer risk. However, warn the patient and gastroenterology team that stopping smoking may trigger a UC flare. Gastroenterology should be made aware so the treatment plan can be adjusted proactively.

The overall health benefit of cessation vastly outweighs the UC risk — manage proactively, not avoid
🧐
Stress Management
Proven to reduce flare frequency in IBD
Mechanism

Psychological stress activates the HPA axis, increases intestinal permeability, and alters gut microbiome composition. Stress is a recognised trigger for UC flares through neuroimmunological mechanisms.

What works

Mindfulness-based stress reduction (MBSR), gut-directed CBT, and relaxation therapy all have evidence in IBD. NHS Talking Therapies referral for anxiety or depression. Peer support groups (Crohn’s & Colitis UK). IBD nurse can facilitate access to psychological support.

CBT and mindfulness reduce self-reported flare frequency and hospitalisation rates in IBD
🍽️
Nutrition During Flares
Adequate protein and calories; dietitian input
What the evidence shows

No specific diet has proven benefit for inducing or maintaining remission in UC (unlike enteral nutrition in Crohn’s). However, nutritional deficiency during flares impairs recovery and increases surgical risk. Adequate protein intake and caloric density are priorities.

Practical guidance

Dietary restrictions should not be imposed unless specific foods are causing symptoms. Dietitian referral for patients with significant weight loss, nutritional deficiencies, or malnutrition during flares. Iron supplementation for anaemia. Vitamin D supplementation for all patients on steroids.

Adequate nutrition reduces complication rates and recovery time during acute flares
🏋
Exercise
150 min/week moderate activity in remission
Evidence

Regular moderate exercise reduces inflammatory cytokine levels, improves mental health, and reduces fatigue in IBD. Exercise-related gut symptoms may be increased during active disease but are manageable with timing of exercise relative to meals and bathroom access.

Practical advice

Encourage regular moderate exercise in remission. During active flares, rest as needed but aim to resume activity as symptoms allow. Yoga and swimming are well-tolerated. RADAR key for accessible toilet access during outdoor activities.

Exercise reduces fatigue, improves mental health, and may reduce inflammatory load in remission
💉
Vaccinations
Immunosuppressed patients: specific schedule required
Why essential

Immunosuppressants (azathioprine, biologics) significantly increase infection risk. Pre-treatment vaccination is essential. Live vaccines are absolutely contraindicated in immunosuppressed patients — they can cause vaccine-strain disease.

Which vaccines

Annual influenza (inactivated), COVID-19 boosters, pneumococcal (PCV13 + PPV23), hepatitis B series (check serology first), VZV serology (give varicella vaccine before immunosuppression if non-immune), HPV per JCVI schedule, meningococcal ACWY. All live vaccines must be given at least 4 weeks before starting immunosuppressants.

Vaccination prevents avoidable infections during immunosuppression; document status before every new immunosuppressant
🚫
NSAID Avoidance
NSAIDs are a recognised UC flare trigger — switch to paracetamol
Mechanism

NSAIDs inhibit cyclooxygenase enzymes, reducing mucosal prostaglandin production. This impairs the gut’s protective mucosal layer and triggers inflammation in patients with UC. Up to 20% of UC flares are associated with NSAID use.

What to advise

All NSAIDs should be avoided in active UC. Paracetamol is safe for analgesia. For patients on anticoagulation with concurrent pain, specialist advice may be needed. Document NSAID avoidance advice in the notes and on the summary care record.

NSAID avoidance is one of the few modifiable triggers with direct evidence for reducing UC flare risk
7D — Prescribing guide: the UC treatment ladder
UC treatment follows a step-up ladder from 5-ASA to steroids to immunomodulators to biologics. Maintenance 5-ASA is the cornerstone of UC management and must be continued lifelong even in remission. Steroids are for acute flares only and should never be used as long-term maintenance. Azathioprine is initiated by gastroenterology after TPMT testing. Biologics (infliximab, vedolizumab, ustekinumab) are specialist-initiated only.
Step 1 — 5-ASA (Mesalazine): first-line and maintenance
  • E1 proctitis: Mesalazine suppository 1g OD (topical) alone is first-line; add oral if response inadequate
  • E2 left-sided: Oral mesalazine 2.4g/day + mesalazine enema 1–4g OD (combined superior to either alone)
  • E3 extensive: Oral mesalazine 4.8g/day (maximum dose) + topical; high-dose oral is superior to standard dose for induction
  • Maintenance: Continue indefinitely at the dose that achieved remission; 5-ASA is both treatment AND CRC chemoprevention
  • Sustained-release preparations (Pentasa, Mezavant) may be better tolerated and offer once-daily dosing, improving adherence
Review at 4 weeks; if inadequate response, increase dose or add topical component before considering steroids
Step 2 — Corticosteroids: acute flares only
  • Oral prednisolone 40mg OD: For moderate-to-severe flare; taper by 5mg/week from week 2 over 8 weeks total
  • Topical budesonide (Budenofalk enema): For left-sided flare; less systemic absorption than prednisolone; useful if systemic steroid side effects are a concern
  • IV hydrocortisone 100mg QDS: Severe UC in hospital only; switch to oral prednisolone 40mg when tolerating oral intake
  • Calcium + vitamin D: Always prescribe alongside steroids (DEXA if >3 months cumulative steroid exposure)
  • 🔴 Steroids are never appropriate maintenance therapy — if required more than 2 courses/year or unable to taper, escalate to immunomodulator
Never start steroids without stool cultures (C. difficile exclusion) · Never continue >8 weeks · Never use as maintenance
Step 3 — Immunomodulators (specialist-initiated)
  • Azathioprine 2–2.5mg/kg/day: First-line immunomodulator for steroid-dependent or steroid-refractory UC; TPMT testing mandatory before initiating; takes 3–6 months for full effect
  • 6-Mercaptopurine (6-MP): Alternative to azathioprine for those who cannot tolerate it (nausea, hepatitis); NOT for azathioprine-induced pancreatitis
  • Monitoring: FBC and LFTs monthly for 3 months, then 3-monthly; sun protection (increased skin cancer risk)
  • Biologics (infliximab, vedolizumab, ustekinumab): For immunomodulator failure or severe refractory disease; specialist-initiated only; GP monitors for infections and attends shared care agreements
TPMT BEFORE azathioprine · FBC + LFTs monthly ×3 then 3-monthly · Never initiate without specialist input
Surgery — colectomy (curative for UC)
  • Colectomy is curative for UC (unlike Crohn’s); used in medically refractory severe UC, complications (perforation, cancer), or patient preference
  • Proctocolectomy with ileo-anal pouch anastomosis (IPAA) is the preferred restorative procedure; allows continence and avoids permanent stoma in most patients
  • Post-colectomy complications: pouchitis (treat with metronidazole or ciprofloxacin), cuffitis (topical mesalazine); refer to IBD team
  • GP role: support during surgical decision-making; refer to IBD nurse; address psychosocial impact of surgery and stoma potential
Cancer Surveillance — colonoscopy intervals (NICE NG151)
  • Low risk (E1 proctitis, E2 <8 years, no other risk factors): colonoscopy every 5 years
  • Intermediate risk (E2–E3, 8–20 years, mild active inflammation, previous dysplasia >5 years ago): every 3 years
  • High risk (pancolitis >20 years, previous dysplasia in last 5 years, PSC, FH CRC <50): annual colonoscopy with chromoendoscopy
  • GP role: ensure surveillance is arranged; document last colonoscopy date; refer urgently if overdue high-risk patient

Check adherence at every review — non-adherence is the single most common reason for UC flares
Formulation matters: sustained-release (Mezavant XL) gives once-daily dosing and improves adherence
💬 Counselling

“Mesalazine is the cornerstone of your treatment — it reduces inflammation, prevents flares, and importantly, it protects against the increased cancer risk that comes with UC over time. It needs to be taken every day, even when you feel completely well. Think of it as a shield, not a fire extinguisher.”

SCA pearl: Non-adherence to mesalazine is the most common reason for UC flares — always explore adherence before escalating treatment. The chemoprevention argument (reduced CRC risk) is the most powerful motivator for adherent patients who are reluctant to take long-term medication. Naming this specifically scores in the Tasks domain.

✓ Recommended for flares
Step 2 — Acute flares only40mg OD tapering over 8 weeks
✓ Use when
Moderate-to-severe UC flare not responding to optimised 5-ASA within 2 weeks
Always prescribe alongside calcium + vitamin D (1000mg calcium + 800 IU vitamin D3 daily)
Taper at 5mg/week from week 2; target completion within 8 weeks
✗ Absolute rules
🔴 NEVER start without stool cultures and C. difficile exclusion — non-negotiable patient safety rule
🔴 NEVER use as maintenance therapy — if needed more than twice a year, escalate to immunomodulator
🔴 NEVER continue beyond 8 weeks without specialist review
Caution in diabetes (hyperglycaemia), hypertension (fluid retention), osteoporosis (bone loss acceleration)
🔬 Monitor
Blood glucose if diabetic; BP monitoring; document steroid exposure dates and doses in notes
DEXA scan if cumulative steroid exposure >3 months/year; bisphosphonate if T-score <–2.5
Review at 2 weeks: if no response to prednisolone, do not continue — refer urgently to gastroenterology
💬 Counselling

“These steroids will help get this flare under control quickly. They are not a long-term treatment — we will reduce them gradually over 8 weeks. They can affect your sleep and appetite, and you might feel a bit more energetic than usual. Take them in the morning with breakfast. Do not stop them suddenly.”

SCA pearl: The two most commonly scored errors in UC prescribing examinations are: (1) starting steroids without stool cultures (C. difficile exclusion) and (2) prescribing steroids as maintenance rather than only for acute flares. Both are patient safety issues and both are explicitly scored. Articulating the taper schedule (5mg/week from week 2) demonstrates clinical depth.

Allopurinol co-prescription: reduces azathioprine metabolism → 75% dose reduction required; major drug interaction
Azathioprine-induced pancreatitis: do NOT rechallenge; switch to 6-MP only under specialist guidance
Live vaccines absolutely contraindicated while on azathioprine; give all live vaccines ≥4 weeks before starting
🔬 Monitor (GP-led)
FBC + LFTs: fortnightly for 8 weeks, monthly for 3 months, then 3-monthly; shared care protocol
WBC <3.5 or neutrophils <1.5: hold azathioprine and contact gastroenterology urgently
Annual skin check: increased melanoma and NMSC risk; advise sun protection SPF50+ and annual dermatology if indicated
💬 Counselling

“This medication reduces the activity of your immune system to prevent further flares. It takes 3–6 months to reach its full effect. During this time, you will need regular blood tests to make sure it is not affecting your blood count or liver. If you develop a fever, come back urgently — your immune system is less able to fight infections while you are on this medication.”

SCA pearl: Three things score in the SCA for azathioprine: (1) TPMT testing before starting; (2) explicit drug interaction warning with allopurinol; (3) blood monitoring schedule (FBC + LFTs). Mentioning the 3–6 month delay to therapeutic effect manages patient expectations about flare prevention. Never initiate without specialist confirmation — say so clearly.

💬 Counselling

“This is a powerful medication that specifically targets the part of the immune system causing inflammation in your bowel. It is given by injection or infusion at the hospital. You will need regular blood tests and checks. The main risk is infection — please come to us urgently if you develop a fever or feel unwell.”

SCA pearl: The GP’s role with biologics is monitoring and recognising complications, not initiating. Demonstrating awareness of TB and hepatitis B screening, live vaccine contraindication, and the shared care model scores in the Tasks domain. Never offer to initiate a biologic without specialist input — this is an examiner red flag.

7G — Psychosocial impact: work, relationships, travel & daily life
🤝
Living with UC — the chronic relapsing-remitting burden
UC does not just affect the bowel — it shapes every aspect of daily life. The unpredictability of flares creates chronic anticipatory anxiety. The urgency and bleeding are undignified and distressing. The cancer risk and colectomy possibility create existential fear. Addressing these domains is as important as the pharmacological management and directly determines adherence and long-term outcomes.
🏢
Work and Legal Rights

UC is a disability under the Equality Act 2010. Employers must make reasonable adjustments including unrestricted toilet access, flexible start times during flares, and time off for appointments. Patients are protected from dismissal due to UC if these rights are documented.

GP letter to employer supporting reasonable adjustments; fit note during flares; occupational health referral; document disability status in medical records.

“You have legal rights as someone with UC. I can write a letter to your employer explaining what adjustments they should make — including unrestricted toilet access. This is protected under the Equality Act.”
✈️
Travel and Urgent Access to Toilets

UC urgency makes travel, commuting, and social activities stressful. Fear of not reaching a toilet in time significantly restricts daily life. The RADAR key scheme provides access to over 10,000 locked accessible public toilets in the UK. Crohn’s & Colitis UK provides a “Not every disability is visible” card for urgent situations.

Register for RADAR key; Crohn’s & Colitis UK membership; “Can’t Wait Card” for urgent toilet access.

“I want to tell you about the RADAR key scheme — it gives you access to accessible toilets across the UK. And Crohn’s & Colitis UK have cards that explain your need for urgent toilet access without embarrassment.”
🧠
Mental Health and Chronic Illness Burden

25–35% of UC patients have clinically significant anxiety or depression. Fear of flares, cancer, and colectomy creates chronic anticipatory anxiety. Depression is associated with non-adherence, hospitalisation, and surgical rates.

PHQ-9 and GAD-7 at every annual review; NHS Talking Therapies referral; IBD nurse psychosocial support; Crohn’s & Colitis UK peer support groups; formal psychological therapy.

“Living with a relapsing condition that comes and goes without warning takes a real toll. How is your mood? I want to make sure we are supporting your mental health as well as your bowel.”
💐
Family Planning and Fertility

Active UC during pregnancy increases risk of preterm birth and low birthweight. Mesalazine is safe in pregnancy. Methotrexate is absolutely contraindicated. Some biologics can be used in pregnancy under specialist guidance. Men on azathioprine should use contraception for 6 months after stopping.

Pre-conception counselling with gastroenterology; ensure disease is in remission before conception; medication review; obstetric co-management; folic acid 5mg OD.

“If you are thinking about starting a family, I want to make sure we plan this carefully with your gastroenterology team — some medications need to be reviewed and it is better to conceive in remission.”
🚪
Fear of Colectomy and Surgery

Colectomy is curative for UC and rates are declining with biologics, but it remains a feared outcome. Many patients make significant life decisions (career choices, family size, relationship decisions) based on an overestimated likelihood of colectomy. Accurate information reduces fear.

Realistic information about surgical rates (approximately 20–30% lifetime risk with good medical management); colostomy is not inevitable — ileo-anal pouch preserves continence in most cases; stoma nurse referral if indicated.

“I hear that the possibility of surgery is something that frightens you. Can I give you some specific information? Most people with UC never need an operation, and for those who do, there are excellent surgical options that allow continence.”
📈
Cancer Surveillance Adherence

Cancer fear both drives and paradoxically prevents surveillance adherence. Some patients miss surveillance colonoscopies because they are afraid of a bad result. This avoidance significantly increases cancer risk by allowing dysplasia to go undetected.

Frame surveillance as empowering rather than alarming: “This colonoscopy is how we catch any changes early, when they are completely treatable.” Document surveillance due dates prominently in the record.

“I know the colonoscopy is something you have been putting off. I understand why — it can feel like you are looking for bad news. But the purpose is actually the opposite: it is how we find any small changes early enough to treat them easily.”
7H — Follow-up schedule

7J — Safety-netting: exact phrases + medico-legal rationale

⚠ Three scenario-specific phrases — use these verbatim

🔴 Emergency — severe flare or surgical complication
“If your symptoms get significantly worse — particularly if you are opening your bowels more than 6 times with blood, develop a fever, or get severe abdominal pain — please go straight to A&E or call 999. Do not wait to see your GP. This is a situation that needs hospital treatment, not primary care management.”
Severe UC and toxic megacolon are medical emergencies with significant mortality if delayed. Patients with UC and a history of moderate flares may not recognise when a flare has escalated to the severe category. Naming the specific criteria (frequency, fever, severe pain) and specifically directing to A&E rather than GP is medico-legally protective.
💊 Immunosuppression — infection risk
“While you are on azathioprine [or a biologic], your immune system is less able to fight infections. If you develop a fever above 38 degrees, feel unusually unwell, or notice any signs of infection, please contact us the same day. This is not something to monitor at home — infections need prompt treatment in immunosuppressed patients.”
Serious infections (including sepsis and opportunistic infections) are significantly more common in patients on azathioprine and biologics. Documenting that the patient has been warned about infection risk and given clear instructions to seek same-day assessment protects against negligence claims if an infection deteriorates.
🟠 Cancer surveillance — do not miss
“Your colonoscopy is due [date]. It is really important that you attend — this is how we pick up any changes before they become a problem. The cancer risk from UC is real but manageable, and this is a central part of managing that risk. Please contact us if you have not received your appointment.”
Cancer surveillance colonoscopies are the primary intervention reducing CRC mortality in UC. Missed surveillance appointments are associated with higher cancer-related mortality. Documenting that the patient has been informed of the surveillance schedule and the reason for it is a core medico-legal requirement in UC management.

Closing the consultation
“Is there anything else on your mind — anything I have said today that you want me to go over again?”
“To summarise: stool sample today, blood tests, the steroid prescription starts once the sample result is back, and I will contact the IBD nurse to let them know about today.”
“The mesalazine needs to be taken every day — not just during flares. It is the main thing that keeps the disease under control and protects you from the long-term cancer risk.”
“If your symptoms get much worse before we speak — particularly fever or severe pain — go straight to A&E, do not wait for a GP appointment.”
“Your next colonoscopy is due [date] — this is your cancer check and it is really important you attend. We will arrange it if it has not been booked.”

Complete the checklist above to see your score interpretation and feedback
“I have been having really bad bloody diarrhoea again — it is happening about 7 or 8 times a day and I feel awful. I have had UC before but this feels much worse. I am terrified it might be cancer this time.”
Who you are

Marcus, 32-year-old software engineer. Diagnosed with UC (E2 left-sided) 4 years ago. Has been on mesalazine 2.4g/day but admits he has been taking it “most days” rather than every day because he feels well between flares. The current flare started 3 weeks ago and has progressively worsened. He has been opening his bowels 7–8 times a day with significant fresh blood. He has a low-grade fever (37.9°C) and his heart rate is 98 bpm. He has lost 3 kg. He had his last colonoscopy 3 years ago.

Hidden agenda and ICE

Terrified of bowel cancer — his uncle died of it and he has noticed the blood is getting worse. He wants to know if this is cancer. He also secretly wants to stop the mesalazine because he read that long-term 5-ASA use causes kidney problems. He is reluctant to go to hospital because he has an important work project. He thinks the flare is related to stress from work.

Symptoms if asked directly
  • Stool frequency: 7–8/day with significant fresh blood
  • Nocturnal symptoms: yes, waking 2–3 times per night to open bowels
  • Fever: yes, feels hot; temperature 37.9°C measured at home
  • Heart rate: 98 bpm (tell if asked or measured)
  • Weight loss: 3 kg over 3 weeks without trying
  • Abdominal pain: lower left abdominal cramping, constant background
  • No perianal symptoms; no joint pain; no eye symptoms
  • Last colonoscopy: 3 years ago; no surveillance appointment received
Bonus details and resolution
  • Mesalazine adherence: approximately 60–70% — discloses if asked non-judgmentally
  • NSAIDs: took ibuprofen for 2 weeks for back pain starting 4 weeks ago (important trigger)
  • Work impact: has missed 5 days in the past 3 weeks; job at risk
  • Resolution: accept hospital admission if clinician explains clearly why home management is unsafe; initially resistant but yields to clinical evidence
  • Challenge phrase: “Can I not just take some steroids at home? I really cannot afford to take time off work right now”
“I really don’t think I need to go to hospital — can I just get some steroids to take at home? I promise I’ll come back if I get worse. I’ve got such an important deadline at work this week.”

Resolution: Accept hospital admission if the clinician explains: (1) the Truelove-Witts criteria (6+ bloody stools + fever + HR >90 = severe UC requiring IV treatment); (2) the risk of toxic megacolon if managed at home; (3) that home oral steroids are not the appropriate treatment for this level of severity. Remain resistant to the examination unless the clinical reasoning is clearly explained. If the clinician identifies the ibuprofen as a trigger and addresses it, award an additional Relating to Others mark. Cancer fear must be specifically addressed — do not accept generic reassurance.

Open — severity first
“I need to ask some specific questions to work out how serious this flare is right now — that determines what we do today.”
Concerns — name cancer fear
“Are you worried this could be cancer? I ask all my UC patients this because it is such a common concern and I want to address it directly.”
Cultures before steroids
“Before steroids, I need a stool sample — if this is a gut infection, steroids could make it significantly worse. This is a safety step, not a delay.”
Explain hospital admission
“Your pulse, temperature, and the severity of your symptoms tell me this needs IV treatment in hospital — oral tablets are not strong enough for this level of disease.”
