The treatment of hyperthyroidism is as follows: 1. Basic treatment: one of the major causes of hyperthyroidism is related to iodine, so a low iodine diet is needed, and foods such as kelp, nori, or seafood should be avoided as much as possible. The two main types of drug therapy are imidazole or propylthiouracil tablets. There is also a category of radioactive drugs called iodine-131, which can be used to treat hyperthyroidism, and most patients can return to normal after iodine-131 treatment. However, thyroid function needs to be monitored regularly in the future, because hypothyroidism may occur. 3. Surgery: For patients with goiter that is obvious and particularly affects the aesthetics, or for patients who are suspected of having malignant potential, surgery can be considered for treatment. Whether you choose medication or iodine-131 treatment or surgery, there are certain indications and contraindications, and you need a doctor to determine which method of treatment is appropriate.
