Causes of hyperthyroidism

The thyroid gland is found in the neck. It produces hormones that are released into the bloodstream to control the body's growth and metabolism. These hormones are called thyroxine and triiodothyronine. They affect processes such as heart rate and body temperature, and help convert food into energy to keep the body going. In hyperthyroidism, the thyroid gland produces too much thyroxine or triiodothyronine, which speeds up the body's metabolism. There are several possible underlying causes, the most common being Graves' disease, in which the body's immune system targets the thyroid gland and causes it to produce too much of the thyroid hormones.
