Hyperthyroidism makes the body speed up.
The most common cause of hyperthyroidism, Graves' disease, is caused by problems with the immune system and tends to run in families. It affects at least 2.5 million Americans, including Olympic athlete Gail Devers who won a gold medal in track after being diagnosed with and treated for Graves' disease. The symptoms of hyperthyroidism rarely occur all at once. However, if you have more than one of these symptoms, and they continue for some time, you should see your doctor. All Rights Reserved.
