Discuss the relationship between hyperthyroidism and Graves' disease
What will be an ideal response?
The most common cause of hyperthyroidism is Graves' disease. This is an autoimmune disease in which the body erroneously produces thyroid-stimulating immunoglobulin (TSI), an antibody whose target is the TSH receptors on the thyroid cells. TSI stimulates both secretion and growth of the thyroid in a manner similar to TSH. Unlike TSH, however, TSI is not subject to negative-feedback inhibition by thyroid hormone, so thyroid secretion and growth continue unchecked. Less frequently, hyperthyroidism occurs secondary to excess TRH or TSH or in association with a hyper-secreting thyroid tumor.
