Graves' disease and thyroid disorders

Graves' disease is an autoimmune disease that causes hyperthyroidism. If a person has hyperthyroidism, they have an overactive thyroid gland, which produces excess hormones.

Graves' disease affects the thyroid gland.

The thyroid gland is in the neck, below the Adam's apple. The hormones that it produces help to regulate growth and the rate of metabolism. The thyroid gland produces the hormones thyroxine and triiodothyronine.

Thyroid eye disease is a condition in which the soft tissues and muscles around the eyes become swollen and inflamed.

It is closely linked to hyperthyroidism, and sometimes to hypothyroidism, which is an underactive thyroid gland.

Hyperthyroidism or hypothyroidism may not immediately cause the eyes to protrude. It may take some time for this to happen.

In a healthy person, the immune systems attack pathogens, the organisms and substances that are bad for us, such as some bacteria, viruses, parasites, cancer cells, and fungi.

In some people, the immune system starts attacking good tissue. These people have an autoimmune disease. In an autoimmune disease, the immune system attacks parts of the body that are needed for good health.

Graves' disease is an example of an autoimmune disease. Experts are not sure why autoimmune diseases, such as Graves' disease, occur.

If the patient's immune system attacks the thyroid gland, the gland may react by producing extra hormones.

The additional thyroid hormone and the autoimmune antibodies may attack the muscles, and soft tissue surrounding the eyes which can cause them to protrude from the socket.
