Abstract: Subclinical hyperthyroidism (SH) is diagnosed in patients having a persistently low or undetectable serum concentration of thyroid-stimulating hormone (TSH) with normal total triiodothyronine, total thyroxine, free triiodothyronine and free thyroxine concentrations, with or without minor symptoms of hyperthyroidism. With the development of the determination method of TSH, the detection rate of SH was increased significantly. Most of the patients with SH can be spontaneous remission without treatment, but there are still some patients to have progress for clinical hyperthyroidism. SH is associated with some serious complications, such as the negative effects on cardiovascular system, osteoporosis, fratures, senile dementia, and so on. It has an important clinical significance to treat SH precisely.

Key words: hyperthyroidism, thyrotropin, therapy
