Hyperthyroidism

Hyperthyroidism happens when the thyroid gland makes too much thyroid hormone. This condition also is called overactive thyroid. Hyperthyroidism speeds up the body's metabolism. That can cause many symptoms, such as weight loss, hand tremors, and rapid or irregular heartbeat. Hyperthyroidism occurs when the thyroid gland overproduces the hormone thyroxine. Hyperthyroidism speeds up your body's metabolism and can cause unintentional weight loss and rapid arrhythmias. There are several treatments for hyperthyroidism.
