General Discussion

Autoimmune thyroiditis (AT), also known as Hashimoto's disease, is a chronic inflammatory disorder of the thyroid gland that is caused by abnormal blood antibodies and white blood cells that mistakenly attack and damage healthy thyroid cells. It is a progressive disease that may destroy the thyroid gland, causing thyroid hormone deficiency (hypothyroidism). Autoimmune thyroiditis presents with various combinations of symptoms, making diagnosis difficult. This disease can occur at any age, but is most often seen in middle-aged women. In rare cases, it may be associated with other autoimmune endocrine disorders.
