Hashimotoâs disease is an autoimmune disease that affects the thyroid. It also is called Hashimotoâs thyroiditis (theye-royd-EYET-uhss). The thyroid is a small gland in the front of the neck. The thyroid makes hormones called T3 and T4 that regulate how the body uses energy. Thyroid hormone levels are controlled by the pituitary, which is a pea-sized gland in the brain.
