Hashimoto's thyroiditis is an autoimmune disease where the body's own T-cells attack the cells of the thyroid. It is the most common cause of hypothyroidism in North America and Europe. It occurs far more often in women than in men (10:1 to 20:1), and is most prevalent between 45 and 65 years of age.
Weight gain, depression, fatigue, panic attacks, high cholesterol, constipation, migraines, memory loss, infertility and hair loss are a few possible symptoms. If untreated for an extended period, Hashimoto's thyroiditis may lead to muscle failure, including possible heart failure.
