  • Symptoms of Hashimoto's thyroiditis are those of hypothyroidism and include
  • Hashimoto's thyroiditis is diagnosed by blood tests that measure thyroid gland function and blood tests that look for antibodies against proteins found in the thyroid gland.

What is Hashimoto's thyroditis?

Hashimoto's thryoiditis is an autoimmune condition that is a common cause of hypothyroidism. In Hashimoto's thyroiditis, the body mounts an immune reaction against its own thyroid gland tissue, leading to inflammation of the gland (thyroiditis).

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.
