If hyperthyroidism is well and then recurs, you can choose antithyroid medication, radioactive iodine treatment, surgery and so on. 1. Antithyroid medication: Hyperthyroidism relapse can be treated with antithyroid medication, which can inhibit the thyroid gland from synthesizing thyroid hormones. The representative drugs are methimazole, propylthiouracil and so on. 2. Radioactive iodine therapy: Radioactive iodine therapy is suitable for the recurrence of hyperthyroidism after surgical treatment, or hyperthyroidism combined with liver, kidney and other organ function damage, radioactive iodine can be used to destroy the thyroid tissue and reduce the production of thyroxine. 3. Surgical treatment: For patients who have been taking medication for a long time, or whose hyperthyroidism recurs after stopping medication, surgical resection can be used. It is recommended to consult a doctor in time to improve the relevant examination and carry out targeted treatment or therapy.
