Hashimoto's thyroiditis, also known as chronic lymphocytic thyroiditis, is an autoimmune disorder and the most frequent cause of primary hypothyroidism in regions where dietary iodine is sufficient. In this condition, the body's own immune system mistakenly attacks the thyroid gland. The attack involves cell-mediated immunity (T-cells) and the production of autoantibodies, most commonly against thyroid peroxidase (TPO antibodies) and thyroglobulin (Tg antibodies). This leads to progressive inflammation, infiltration of lymphocytes, and destruction of thyroid follicular cells. Over time, the damaged gland becomes less able to produce thyroid hormones, leading to a gradual onset of hypothyroid symptoms. It is more common in women and often has a genetic predisposition. Environmental factors, including potential triggers like viral infections or certain chemicals, are also areas of investigation.
