Hyperthyroidism is a thyrotoxicosis caused by excessive production of thyroid hormones by the thyroid gland itself. The treatment methods mainly include medication, iodine 131 treatment and surgery, etc. It is recommended to follow the doctor’s instructions for treatment. 1. Drug therapy: anti-thyroid drugs such as methimazole and propylthiouracil are suitable for patients with mild symptoms who are not suitable for surgery, and for the preparatory stage before thyroidectomy and iodine 131 treatment. 2. Iodine 131 treatment: Iodine 131 can destroy the thyroid tissue and reduce the production of thyroid hormone to treat hyperthyroidism. It is suitable for patients with thyroid enlargement of more than two degrees; allergic to anti-thyroid drugs; and patients who have relapsed after medication or surgical treatment. 3. Surgery: Subtotal thyroidectomy, applicable to patients with severe enlargement of thyroid gland producing pressure symptoms, ineffective treatment with antithyroid drugs, suspected cancer or post-thyroid enlargement. It is recommended that patients with hyperthyroidism go to regular hospitals in time to improve the relevant examinations and standardize the treatment under the doctor’s guidance, so as to avoid delaying the condition or causing adverse reactions.
