What should hyperthyroidism do after hypothyroidism? Is it for hyperthyroidism or hypothyroidism?

Hello, hyperthyroidism is a disease caused by increased thyroid hormone secretion. At present, the cause is not clear. At present, there are three main methods to treat hyperthyroidism: drugs, iodine 13 1 radiotherapy and surgery. Medication is usually the first consideration. Drug therapy generally takes more than two years to cure, and the recurrence rate is relatively high, which is not easy to lead to hypothyroidism. Iodine 13 1 radiotherapy is convenient, with high cure rate and low recurrence rate, but its disadvantage is high cost and easy to lead to hypothyroidism. The trauma of operation is relatively large, and it is usually suitable for cases where the first two methods are ineffective or relapse and there are some contraindications.
