Signs of Hyperthyroidism

Hyperthyroidism occurs when the thyroid overproduces hormones that control the body's metabolism.

The American Academy of Family Physicians lists these common warning signs of hyperthyroidism:

*Sudden, unexplained weight loss.
*Weakened muscles and fatigue.
*Feelings of nervousness and anxiousness.
*Excessive sweating.
*Rapid heartbeat.
*Tremors.
*Eyes that are red, wide, or swollen

The academy says other diseases and conditions can mimic these symptoms, so your doctor may run some tests to confirm a suspected diagnosis.
