Hashimoto's thyroiditis is the most common cause of hypothyroidism (having too low levels of thyroid hormones) in the United States. The condition was named after Dr. Hakaru Hashimoto, the doctor who described it in 1912.
What causes Hashimoto's thyroiditis?
Hashimoto's thyroiditis is a condition caused by inflammation of the thyroid gland. It is an autoimmune disease, which means that the body inappropriately attacks the thyroid gland - as if it was foreign tissue. The underlying cause of the autoimmune process remains unknown. Hashimoto's thyroiditis tends to occur in families. It can be associated with other autoimmune conditions such as type 1 diabetes or celiac disease. Hashimoto's thyroiditis is 5 to 10 times more common in women than in men and most often starts in adulthood. Blood drawn from people with Hashimoto's thyroiditis typically reveals an increased number of antibodies against thyroid-specific proteins, including thyroperoxidase and thyroglobulin. T lymphocytes, a type of cell involved in the inflammation process, invade the thyroid gland cause silent, painless inflammation that destroys it; ultimately, the individual produces little or no thyroid hormone and becomes hypothyroid.
Thyroid peroxidase (TPO) is an enzyme made in the thyroid gland that is important in the production of thyroid hormone. TPO is found in thyroid follicle cells where it converts the thyroid hormone T4 to T3./"...
