Health Tip: Signs of Hyperthyroidism

An overactive thyroid

(HealthDay News) -- 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.
