Hyperthyroidism is cured, but thyroid stimulating hormone receptor antibody (TRAb) is high and low, indicating that it may not be completely cured. Cure of hyperthyroidism is determined by 6 criteria, including clinical symptoms, blood levels of thyroid hormones, thyroid hormone receptor antibodies, etc. The patient is cured only if clinical symptoms disappear, blood levels of hormones are normal, and thyroid hormone levels are consistently negative for consideration. Patients without symptoms of increased basal metabolic rate and sympathetic excitation, with normal thyroid hormone levels, but with the presence of increased TRAb are considered to be at risk of relapse, so at this time it is still necessary to use drugs that inhibit the secretion of thyroid hormones, and to control the drugs to the minimum maintenance dose until the thyroid hormone receptor antibodies become consistently negative. When patients with hyperthyroidism are found to have elevated TRAb, it is recommended that they consult the endocrinology department of a regular hospital.
