Hashimoto’s Disease

When the immune system attacks the butterfly-shaped gland in the neck (thyroid).


Hashimoto’s thyroiditis or chronic lymphocytic thyroiditis is an autoimmune disease in which the thyroid gland is attacked by a variety of cell – and antibody-mediated immune processes, causing primary hypothyroidism. It was the first disease to be recognized as an autoimmune disease. It was first described by the Japanese specialist Hakaru Hashimoto in a paper published in Germany in 1912.
