what hormone causes graves disease
Gravesâ disease is an autoimmune disorder. It causes your thyroid gland to create too much thyroid hormone in the body. This condition is known as hyperthyroidism. Gravesâ disease is one of the most common forms of hyperthyroidism. In Gravesâ disease, your immune system creates antibodies known as thyroid-stimulating immunoglobulins. These antibodies then attach to healthy thyroid cells. They can cause your thyroid to create too much thyroid hormone.
