Hashimoto's thyroiditis is an autoimmune disease that attacks the thyroid gland. The thyroid gland is a small, butterfly-shaped gland in the front of the neck that produces hormones that regulate the body's metabolism.
Hashimoto's thyroiditis is the most common cause of hypothyroidism (an underactive thyroid) in the United States. It usually develops slowly over years and can lead to goiter (an enlarged thyroid gland).
Hashimoto's thyroiditis is more common in women and people with a family history of the condition. The main symptom of Hashimoto's thyroiditis is hypothyroidism, which can cause fatigue, weight gain, and depression.
Hashimoto's Thyroiditis is treated with thyroid hormone replacement therapy, which can help manage the symptoms.
