Hashimoto's disease is a disorder that affects your thyroid, a small gland at the base of your neck, below your Adam's apple. The thyroid gland is part of your endocrine system, which produces hormones that coordinate many of your body's activities.
In Hashimoto's disease, also known as chronic lymphocytic thyroiditis, your immune system attacks your thyroid gland. The resulting inflammation often leads to an underactive thyroid gland (hypothyroidism). Hashimoto's disease is the most common cause of hypothyroidism in the United States. It primarily affects middle-aged women, but also can occur in men and women of any age and in children.
Doctors test your thyroid function to help detect Hashimoto's disease. Treatment of Hashimoto's disease with thyroid hormone replacement usually is simple and effective.
