Autoimmune thyroiditis (AIT) refers to a group of disorders characterized by the presence of autoantibodies against the thyroid in the serum, lymphocytic infiltration within the thyroid gland, and varying degrees of thyroid tissue destruction. Conditions under this category include Hashimoto thyroiditis, painless thyroiditis, and postpartum thyroiditis. Thyroid function in these conditions may be normal, or patients may exhibit thyrotoxicosis or hypothyroidism. This section focuses on Hashimoto thyroiditis and painless thyroiditis.
