Hashimoto's thyroiditis

Hashimoto's thyroiditis is an autoimmune organ-specific disease in which the immune system attacks its own thyroid gland, characteristically damaging its structure and function. The course of a chronic inflammatory process in the gland damages its cells with the loss of functioning thyroid tissue and the development of permanent hypothyroidism in the long term.

The disease can occur both with increased gland function and with normal or decreased function.

Because due to the autoimmune process, many lymphocytes settle in it, over the years the glandular tissue is lost and this leads to an inactive thyroid gland (hypothyroidism)
