Graves disease is the most common cause of hyperthyroidism. Graves disease is an autoimmune disorder in which antibodies are produced that bind to the TSH receptor.s diagrammed in the figure, when there is less T3 and T4, there is reduced negative feedback inhibition of secretion of the tropic hormones, TRH (thyrotropin releasing hormone; released by the hypothalamus) and TSH (thyroid stimulating hormone or thyrotropin; released by the anterior pituitary).
However, TSI also stimulates the thyroid to make too much thyroid hormone (causes hyperthyroidism). Since the pituitary senses too much thyroid hormone, it stops secreting TSH. In spite of this the thyroid gland continues to grow and make thyroid hormone. Therefore, Gravesâ disease produces a goiter and hyperthyroidism. goiter can occur in a gland that is producing too much hormone (hyperthyroidism), too little hormone (hypothyroidism), or the correct amount of hormone (euthyroidism). A goiter indicates there is a condition present which is causing the thyroid to grow abnormally.
