Learn About Graves Disease

What is the definition of Graves Disease?

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.

What are the causes of Graves Disease?

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.

When the body makes too much thyroid hormone, the condition is called hyperthyroidism. (An underactive thyroid leads to hypothyroidism.)

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.

What are the symptoms of Graves Disease?

Younger people may have these symptoms:

  • Anxiety or nervousness, as well as problems sleeping
  • Breast enlargement in men (possible)
  • Problems concentrating
  • Fatigue
  • Frequent bowel movements
  • Hair loss
  • Heat intolerance and increased sweating
  • Increased appetite, despite having weight loss
  • Irregular menstrual periods in women
  • Muscle weakness of the hips and shoulders
  • Moodiness, including irritability and anger
  • Palpitations (sensation of a strong or unusual heartbeat)
  • Rapid or irregular heartbeat
  • Shortness of breath with activity
  • Tremor (shakiness of the hands)

Many people with Graves disease have problems with their eyes:

  • The eyeballs may seem to be bulging out and may be painful.
  • Eyes can feel irritated, itchy, or tear more frequently.
  • Double vision may be present.
  • Decreased vision and damage to the cornea can also occur in severe cases.

Older people may have these symptoms:

  • Rapid or irregular heartbeat
  • Chest pain
  • Memory loss or decreased concentration
  • Weakness and fatigue

What are the current treatments for Graves Disease?

Treatment is aimed at controlling your overactive thyroid. You may receive one or more types of treatment.

Beta-blocker medicines may help treat:

  • Rapid heart rate
  • Sweating
  • Anxiety

They may be given until the hyperthyroidism is controlled.

Antithyroid medicines:

  • Block or change how the thyroid gland uses iodine
  • May be used to control the overactive thyroid gland before surgery or radioiodine therapy
  • May be used as a long-term treatment

Radioactive iodine is given by mouth. It then concentrates in the overactive thyroid tissue and causes damage.

Surgery may be done to remove the thyroid.

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.


Some of the eye problems related to Graves disease often improve after treatment with medicines, radiation, or surgery. Radioiodine therapy can sometimes make eye problems worse. Eye problems are worse in people who smoke, even after the hyperthyroidism is treated.

Sometimes, prednisone is needed to reduce eye irritation and swelling. Prednisone is a steroid medicine that suppresses the immune system.

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.

What is the outlook (prognosis) for Graves Disease?

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:

  • Depression
  • Mental and physical sluggishness
  • Weight gain
  • Dry skin
  • Constipation
  • Cold intolerance
  • Abnormal menstrual periods in women
When should I contact a medical professional for Graves Disease?

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 911 or the local emergency number if you have symptoms of hyperthyroidism with:

  • Decrease in consciousness
  • Fever
  • Rapid, irregular heartbeat
  • Sudden shortness of breath

What are the latest Graves Disease Clinical Trials?
Randomized Controlled Trial of Preoperative Corticosteroids in Autoimmune ThyroidDisease

Summary: This study proposes to randomize patients about to undergo surgery for their autoimmune, inflammatory thyroid disease, and determine if a short course of corticosteroids decreases the inflammation of the gland and makes surgery less difficult.
