Whether or not lifelong medication is needed after thyroid treatment depends on the type of thyroid disease and whether or not the function of the thyroid gland recovers as well as complications, e.g., patients with hypothyroidism caused by thyroidectomy may need lifelong medication. Hyperthyroidism usually does not require lifelong medication; patients can be cured of hyperthyroidism with medication, and the medication can be gradually stopped after cure. Patients with hypothyroidism usually need to take medication for life, usually because hypothyroidism caused by diseases, such as immune thyroid disease, Hashimoto’s thyroiditis, etc., cannot be reversed, so they need to take medication for life. Patients with hypothyroidism after thyroidectomy also need to take medication for life. It is recommended to use medication under the guidance of a doctor and not to apply it on your own.
