Hyperthyroidism Complications
- Cardiac complications include rapid heart rate, congestive heart failure, and atrial fibrillation.
- Thyroid crisis or "storm" is an acute worsening or exaggeration of the symptoms of hyperthyroidism that may occur with infection or stress. Fever, decreased mental alertness, and abdominal pain may occur, and immediate hospitalization is indicated.
- Hyperthyroidism increases the risk for osteoporosis.
- Complications related to surgery, including visible scarring of the neck, hoarseness due to nerve damage to the voicebox, and a low calcium level because of damage to the parathyroid glands.
- Complications related to replacement of thyroid hormones. If too little hormone is given, symptoms of under-active thyroid can occur including fatigue, increased cholesterol levels, mild weight gain, depression, and slowing of mental and physical activity.
