Hyperthyroidism is a common clinical autoimmune disease caused by the overproduction of thyroid hormones, resulting in hyper-metabolism and increased neuroexcitability. The treatment of hyperthyroidism currently consists of three main methods: antithyroid drugs, surgery and radioisotope 131 iodine. I. Internal medicine: Anti-thyroid drugs have been widely used in China because of their longevity, safety and convenience. The treatment of antithyroid drugs needs to be regulated under the guidance of a doctor, and the medication can only be stopped after at least 1.5-2 years, but the recurrence rate is still as high as 40%-50%, and may cause liver function damage, leukopenia, and even life-threatening exfoliative dermatitis in some patients. Therefore, the use of the process should be regularly tested and followed up. Second, surgical methods: surgical removal of the thyroid gland, generally only used in patients with huge thyroid gland symptoms such as tracheal compression, because it is invasive treatment, there is a risk of nerve damage after surgery, resulting in hoarseness, coughing and choking, post-operative hypothyroidism is also more common. Radioisotope 131 iodine method: 131 iodine has become the preferred method of hyperthyroidism treatment in the United States and Canada because of its exact efficacy, safety and convenience, and low cost. Its total efficiency is as high as 95%, with a clinical cure rate of over 85% and a recurrence rate of less than 1%.
