Graves’ disease is an autoimmune disease that affects the thyroid gland. In this disease, there is an overproduction of thyroid hormones. Thyroid hormones control the body’s metabolism, so they affect almost all the organs of the body. Hyperthyroidism predominantly affects the following organs:

  • Heart: The abnormally high heart rhythm, called atrial fibrillation occurs in about 20% of people. A heart condition called mitral valve prolapse in which the mitral valve is weakened causing irregular heartbeat is seen in children.
  • Bones: The bones of a person suffering from hyperthyroid are brittle and prone to fractures.
  • Muscles: Weak muscles with an increased tendency to weakness and swelling is seen.
  • Nervous system: Tremors, irritability, and anxiety may be seen.
  • Gut: Diarrhea is seen.

Also, Graves disease affects the menstrual cycle and fertility. Complications of Graves disease include:

What causes Graves disease?

Graves disease is an autoimmune disorder in which the immune system releases abnormal antibodies that mimic the thyroid-stimulating hormone (TSH). TSH, released by the pituitary gland, activates the thyroid gland to produce thyroid hormones. Abnormal antibodies lead to the overproduction of thyroid hormones. Hereditary can play a major role in determining the susceptibility of abnormal antibodies.
