Thyroid Management
Treat the biochemical pattern and the patient — then give the axis time to equilibrate.
Confirm the diagnosis before adjusting
TSH and FT4 patterns distinguish overt, subclinical, and central disease; do not dose-adjust from an isolated misleading value.
Administration matters
Levothyroxine timing, adherence, food, calcium, iron, and other interacting medications can change TSH control.
Do not recheck too early
TSH takes weeks to equilibrate after a dose change. Premature testing can lead to serial overcorrection.
Individualize the target
Age, pregnancy, cardiac disease, symptoms, osteoporosis/arrhythmia risk, and pituitary disease can change management priorities.
