What is Thyroiditis?
Thyroiditis meaning An inflammation of the thyroid gland. Chronic lymphocytic thyroiditis (Hashimoto's thyroiditis) is the most common form of thyroid inflammation. Classified as an autoimmune disorder, Hashimoto's thyroiditis occurs when one's own body makes antibodies to attack the thyroid cells. This results in the destruction of functioning thyroid cells and reduces the thyroid's ability to make thyroid hormone. Hashimoto's thyroiditis is the most common reason people develop hypothyroidism (an underactive thyroid gland). A person with hypothyroidism has to take thyroid hormone pills to keep the level of the hormone normal. The cause of the thyroiditis is not known, but it is most likely a combination of the person's immune system and some environmental factors.
