Hashimoto's thyroiditis, or Hashimoto's disease, is a disorder that affects the thyroid gland. Hashimoto's thyroiditis is also known as chronic autoimmune thyroiditis and chronic lymphocytic thyroiditis.
The name Hashimoto's thyroiditis comes from the pathologist who in 1912 first described the microscopic features of the disease. Hashimoto's disease is the most common cause of hypothyroidism in iodine-sufficient areas throughout the world such as the United States. In general, there is a gradual loss of thyroid function, often accompanied by enlargement of the thyroid gland, also known as a goiter. Hashimoto's disease is most common in middle-aged women and tends to run in families.
As a brief background, the thyroid is responsible for producing hormones that exert control over and participate in a number of metabolic functions such as temperature and heart rate regulation, and metabolism.
