When hyperthyroidism relapses repeatedly, we should first make clear what the reason is, and see what factors lead to the recurrence of hyperthyroidism. In this case, we can try our best to avoid these factors after the disease is stable. In addition, if the patient has recurrent hyperthyroidism, you can consider changing the treatment method. For example, if the effect of patients previously treated with oral medicine is really not very good, and relapse is likely to occur after drug withdrawal, then you can choose surgical treatment. Surgical treatment can be used for those patients who recur repeatedly after drug treatment. Of course, preparation for surgery should be made in advance before surgery. Antithyroid drugs should be used to control the metabolic state of patients. Before surgery, thyroid function should be close to normal, and the resting heart rate should be controlled below 90 times per minute, which can significantly reduce the mortality rate of surgery, Compound iodine solution can be used to reduce thyroid hyperemia and bleeding during and after operation. Moreover, compound iodine solution must be used on the basis of normal function of antithyroid drugs, otherwise it may aggravate the disease.
