Hashimoto's thyroiditis is now considered the most prevalent autoimmune disease, as well as the most common endocrine disorder. It was initially described in 1912, but only rarely reported until the early 1950s.

Where did Hashimoto's disease come from?

Doctors don't know exactly why some people develop Hashimoto's disease. Some researchers think it could be caused by exposure to bacteria or a virus, while others say that genetics may be to blame. Regardless of the cause, there are several common risk factors that many people with Hashimoto's disease share.

Is Hashimoto's a real disease?

Hashimoto's thyroiditis can cause your thyroid to not make enough thyroid hormone. It is an autoimmune disease. It occurs when your body makes antibodies that attack the cells in your thyroid. Symptoms may include an enlarged thyroid gland (goiter), tiredness, weight gain, and muscle weakness.
