Graves Disease


Graves disease is an autoimmune disease that causes your immune system to attack your thyroid gland. This causes your body to make too much thyroid hormone and leads to hyperthyroidism. The thyroid gland is a butterfly-shaped organ that is found in the front part of your neck. Thyroid hormones regulate body temperature, heart rate, and weight.
