Graves' disease
Graves' disease, also known as toxic diffuse goiter and Flajani-Basedow-Graves disease, is an autoimmune disease that affects the thyroid. It frequently results in hyperthyroidism and an enlarged thyroid. Signs and symptoms of hyperthyroidism may include irritability, muscle weakness, sleeping problems, a fast heartbeat, poor tolerance of heat, diarrhea, and weight loss. Other symptoms may include thickening of the skin on the shins, known as pretibial myxedema, and eye problems such as bulging, a condition known as Graves' ophthalmopathy. About 25% to 80% of people develop eye problems.The exact cause is unclear; however, it is believed to involve a combination of genetic and environmental factors. A person is more likely to be affected if they have a family member with the disease. If one twin is affected there is a 30% chance the other twin will also have the disease. The onset of disease may be triggered by stress, infection, or giving birth. Those with other autoimmune diseases such as type 1 diabetes and rheumatoid arthritis are more likely to be affected. Smoking increases the risk of disease and may make the eye problems worse. The disorder results from an antibody, called thyroid stimulating immunoglobulin (TSI), that has a similar effect to thyroid stimulating hormone (TSH). These antibodies cause the thyroid gland to produce excess thyroid hormone. The diagnosis may be suspected based on symptoms with blood tests and radioiodine uptake used to confirm the disease. Typically blood tests show a raised T3 and T4, low TSH, increased radioiodine uptake in all areas of the thyroid, and TSI antibodies.There are three treatment options: radioiodine therapy, medications, and thyroid surgery. Radioiodine therapy involves taking iodine-131 by mouth which is then concentrated in and destroys the thyroid over weeks to months. The resulting hypothyroidism is treated with synthetic thyroid hormone. Medications such as beta blockers may control the symptoms and anti-thyroid medications such as methimazole may temporarily help people while other treatments are having effect. Surgery to remove the thyroid is another option. Eye problems may require additional treatments.Graves' disease occurs in about 0.5% of people. It occurs about 7.5 times more often in women than men. Often it starts between the ages of forty and sixty. It is the most common cause of hyperthyroidism in the United States (about 50% to 80% of cases). The condition is named after Robert Graves who described it in 1835. A number of prior descriptions also exist.
