Hyperthyroidism refers to hyperthyroidism. Antithyroid medication for hyperthyroidism is divided into 3 phases: control phase, tapering phase and maintenance phase. At different phases, the dosage and duration of the antithyroid medication are different, and need to be decided in conjunction with the patient’s personal situation. There is no authoritative information on the treatment cycle of this disease. According to relevant surveys, in general, the treatment cycle of this disease is about 1~1.5 years on average, which may end earlier if the patient’s condition is milder and his/her physical condition is better. If the condition is heavier and the physical quality is poor, the treatment time will be extended. Therefore, the specific treatment cycle time can not be generalized, there are obvious individual differences, the actual situation should prevail. Usually, the prognosis of hyperthyroidism is better after timely and standardized treatment, and patients need to follow up on time and closely monitor the changes in their condition. To summarize, once diagnosed with hyperthyroidism, patients should go to the hospital in a timely manner, cooperate with the doctor for active treatment, and strengthen daily life management.
