Overview | Symptoms | Treatment | Prevention

Alternative names:

Thyrotoxicosis; Overactive thyroid

Treatment

Treatment will vary depending on the cause of the condition and the severity of symptoms. Hyperthyroidism is usually treated with antithyroid medications, radioactive iodine, or surgery.

Beta-blockers (e.g., propranolol) are used to treat some of the symptoms including rapid heart rate, sweating, and anxiety until the hyperthyroidism is controlled.

Prognosis

Hyperthyroidism caused by Graves' disease is usually progressive and has associated complications. Recurrences of hyperthyroidism are common. However, hyperthyroidism is generally treatable and rarely fatal.

Complications

• Cardiac complications include rapid heart rate, congestive 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.
