What is Hashimoto's thyroiditis?

Hashimoto's thyroiditis, also known as chronic lymphocytic thyroiditis, is a non-infectious autoimmune disease. Its exact cause is not fully understood, but it is generally believed to result from the interaction of genetic and autoimmune factors. The typical feature of Hashimoto's thyroiditis is painless diffuse enlargement of the thyroid gland. As the disease progresses, symptoms of hypothyroidism, such as fatigue, weight gain, and emotional instability, may gradually develop. Laboratory tests often show abnormalities in thyroid function indicators, such as decreased levels of triiodothyronine and thyroxine, and elevated thyroid-stimulating hormone. Treatment depends on the severity of the disease and may include regular monitoring, medication, or surgical intervention. Because Hashimoto's thyroiditis has a subtle onset and progresses slowly, early detection and early treatment are recommended.
