Does endocrinology perform thyroid hormone replacement?

Thyroid hormone replacement commonly uses levothyroxine to replace a hormone the thyroid is not making in sufficient amounts. The endocrinologist considers symptoms, thyroid blood tests, age, pregnancy status, heart health, and other medicines before choosing a starting plan. Follow-up testing helps show whether the dose is suitable. Absorption can be affected by food, supplements, and some medicines, so timing instructions matter. A dose that suits one person may not suit another.

Take the medicine exactly as directed and keep a consistent routine. Tell your clinician about calcium or iron supplements, antacids, heart medicines, pregnancy, and changes in symptoms. Do not double a missed dose unless your prescriber gives that instruction. Keep follow-up appointments so testing can guide adjustments, and do not switch brands or change the dose without medical advice.

Seek urgent help for chest pain, severe breathlessness, fainting, marked confusion, or a very fast or irregular heartbeat. Contact your clinician if you develop new shaking, sweating, diarrhoea, pronounced sleepiness, worsening swelling, or persistent symptoms after starting or changing treatment. Pregnancy or a planned pregnancy should be discussed promptly because thyroid needs may change.

Ask when to take the tablet, which products can interfere with absorption, when testing is due, and what symptoms suggest the dose needs review.
