Graves disease is an autoimmune disorder that leads to an overactive thyroid gland (hyperthyroidism). An autoimmune disorder is a condition that occurs when the immune system mistakenly attacks healthy tissue.
The thyroid gland is an important organ of the endocrine system. The gland is located at the front of the neck above where the collarbones meet. This gland releases the hormones thyroxine (T4) and triiodothyronine (T3), which control body metabolism. Controlling metabolism is important for regulating mood, weight, and mental and physical energy levels.
Graves disease is the most common cause of hyperthyroidism. It is due to an abnormal immune system response that causes the thyroid gland to produce too much thyroid hormone. Graves disease is most common in women over age 20. But the disorder can occur at any age and can affect men as well.
Younger people may have these symptoms:
Many people with Graves disease have problems with their eyes:
Older people may have these symptoms:
The health care provider will do a physical exam and may find that you have an increased heart rate. An exam of your neck may find that your thyroid gland is enlarged (goiter).
Other tests include:
This disease may also affect the following test results:
Treatment is aimed at controlling your overactive thyroid. Medicines called beta-blockers are often used to treat symptoms of rapid heart rate, sweating, and anxiety until the hyperthyroidism is controlled.
Hyperthyroidism is treated with one or more of the following:
If you have had radioactive iodine treatment or surgery, you will need to take replacement thyroid hormones for the rest of your life. This is because these treatments destroy or remove the gland.
TREATMENT OF THE EYES
Some of the eye problems related to Graves disease often improve after treatment with medicines, radiation, or surgery to treat the overactive thyroid. Radioiodine therapy can sometimes make eye problems worse. Eye problems are worse in people who smoke, even after the hyperthyroidism is treated.
Sometimes, prednisone (a steroid medication that suppresses the immune system) is needed to reduce eye irritation and swelling.
You may need to tape your eyes closed at night to prevent drying. Sunglasses and eye drops may reduce eye irritation. In rare cases, surgery or radiation therapy (different from radioactive iodine) may be needed to prevent further damage to the eye and loss of vision.
Graves disease often responds well to treatment. Thyroid surgery or radioactive iodine often will cause an underactive thyroid (hypothyroidism). Without getting the correct dosage of thyroid hormone replacement, hypothyroidism can lead to:
Call your provider if you have symptoms of Graves disease. Also call if your eye problems or other symptoms get worse or do not improve with treatment.
Go to the emergency room or call the local emergency number (such as 911) if you have symptoms of hyperthyroidism with:
