“My thyroid is the answer”

Subclinical hypothyroidism (mildly raised TSH, normal T4, antibody-negative) in a 52-year-old usually does NOT warrant levothyroxine on request — at a TSH below 10 and antibody-negative, treatment rarely relieves non-specific symptoms and has downsides. NICE NG145 sets the plan: repeat TSH and free T4 3 months after the first test (her 4-week repeat was too early to confirm it); consider levothyroxine if TSH is 10 or higher on 2 tests 3 months apart; for a symptomatic adult under 65 with TSH above range but below 10 on 2 tests 3 months apart, consider a 6-month trial and stop it if symptoms persist once TSH is in range; if untreated and antibody-negative, recheck TSH every 2–3 years. The trial is discussable rather than flatly refused. But the trap is a dismissive "your thyroid is fine" — which confirms the patient’s fear of being fobbed off. The skill is to believe the symptoms, decline the wrong tablet kindly, and widen the lens: perimenopause is screaming from the erratic periods and flushes, and the hidden agenda is a recent divorce and unnamed low mood for which the thyroid is a socially acceptable shelter. Name those gently, screen mood, and agree a shared plan that keeps her engaged.
