Hyperthyroidism is the condition that reflects excessive concentrations of thyroid hormones, due to any cause. The resulting hypermetabolic state causes increased heat production and accelerates many of the bodies' processes. Common causes are Graves' disease, hyperfunctioning benign thyroid tumors, and thyroid inflammations. Untreated, patients may have severe and progressive disability that includes weight loss, muscle weakness, loss of mineral from their bones, and increased risk for dangerous heart arrhythmias. Available treatments include one of several "antithyroid drugs," such as methimazole and propylthiouracil, that prevent overproduction of thyroid hormones, and radioctive iodine (I-131) treatment or surgery, which either destroy or remove the thyroid tissue.
