Hyperthyroidism

The overproduction of a hormone by the butterfly-shaped gland in the neck (thyroid).
Hyperthyroidism is the production of too much thyroxine hormone. It can increase metabolism. Symptoms include unexpected weight loss, rapid or irregular heartbeat, sweating and irritability, although the elderly often experience no symptoms. Treatments include radioactive iodine, medication and sometimes surgery.
Hyperthyroidism (overactive thyroid) occurs when your thyroid gland produces too much of the hormone thyroxine. Hyperthyroidism can accelerate your body’s metabolism, causing unintentional weight loss and a rapid or irregular heartbeat.
Several treatments are available for hyperthyroidism. Doctors use anti-thyroid medications and radioactive iodine to slow the production of thyroid hormones. Sometimes, hyperthyroidism treatment involves surgery to remove all or part of your thyroid gland.
