What is Graves' disease?

Graves' disease is the leading cause of hyperthyroidism. According to the Graves' Disease and Thyroid Foundation, about2-3 percent of the population - about 10 million people - have this disorder.

The Virginia Mason Institute state that as many as 70-80 percent of patients with hyperthyroidism have Graves' disease. It is an autoimmune condition where the immune system attacks the thyroid gland. In response, the thyroid makes too much thyroid hormone.

The pituitary gland releases the hormone that helps control thyroid function. The thyrotropin receptor antibody (TRAb) is linked with Graves' disease, and it works like the regulatory pituitary hormone. As a result, the TRAb overrides the normal regulation of the thyroid and causes hyperthyroidism.
