Hyperthyroid patients presenting with thyrotropin always 0.0001 μIU/ml are usually able to recover. The normal range of thyrotropin is 0.35 to 5.5 μIU/ml, so thyrotropin 0.0001 μIU/ml is low. Hyperthyroidism patients with thyrotropin 0.0001μIU/ml can be treated with antithyroid drugs such as methimazole, propoxythiazole, etc. Since the recovery process of thyrotropin is slower than that of thyroid hormone, it takes a period of time to see the effect of the drug, but it is often possible to recover after standardized treatment. In addition, thyroid stimulating hormone can be restored to the normal range by iodine radiation therapy and surgery. Patients with hyperthyroidism who have a thyrotropin level of 0.0001 μIU/ml are advised to go to the hospital and ask the doctor to make a judgment.
