Hashimoto's Thyroiditis

What is Hashimoto's thyroiditis

Hashimoto's Thyroiditis is a type of autoimmune thyroid disease in which the immune system attacks and destroys the thyroid gland. The thyroid helps set the rate of metabolism, which is the rate at which the body uses energy. Hashimoto's stops the gland from making enough thyroid hormones for the body to work the way it should. It is the most common thyroid disease in the U.S.

What is an autoimmune disease?

An autoimmune disease occurs when the body's immune system becomes misdirected and attacks the organs, cells or tissues that it was designed to protect. About 75% of autoimmune diseases occur in women, most often during their childbearing years.

What are the symptoms of Hashimoto's thyroiditis?

Some patients with Hashimoto's Thyroiditis may have no symptoms. However, the common symptoms are fatigue, depression, sensitivity to cold, weight gain, forgetfulness, muscle weakness, puffy face, dry skin and hair, constipation, muscle cramps, and increased menstrual flow. Some patients have major swelling of the thyroid gland in the front of the neck, called goiter.

Does this disease run in families?

There is some evidence that Hashimoto's Thyroiditis can have a hereditary link. If autoimmune diseases in general run in your family, you are at a higher risk of developing one yourself.

How can I know for sure if I have this disease?

Your doctor will perform a simple blood test that will be able to tell if your body has the right amount of thyroid hormones. This test measures the TSH (thyroid stimulating hormone) to find out if the levels are in the normal range. The range is set by your doctor and should be discussed with you. Work with your doctor to figure out what level is right for you. There are other available tests that your doctor may choose to do if need be, such as a blood test to measure the level of "active thyroid hormone" or Free T4 and a scan (picture) to look at the thyroid.
