Hypothyroidism is an Endocrine System condition in which the thyroid gland doesn't produce enough thyroid hormone. It is also called underactive thyroid disease.

The thyroid gland is located in the front lower part of your neck. Hormones released by the gland travel through your bloodstream and affect nearly every part of your body, from your heart and brain, to your muscles and skin.

The most common cause of hypothyroidism is Hashimoto's thyroiditis. "Thyroiditis" is an inflammation of the thyroid gland. Hashimoto's thyroiditis is an autoimmune disorder. With Hashimoto’s, your body produces antibodies that attack and destroy the thyroid gland. Thyroiditis may also be caused by a viral infection.

What causes hypothyroidism is pregnancy, problems with the thyroid at birth, pituitary gland disorder, and disorder of the hypothalamus,

Women, particularly older women, are more likely to develop hypothyroidism than men. You are also more likely to develop hypothyroidism if you have a close family member with an autoimmune disease. Other risk factors include:

  • Race (being white or Asian)
  • Age (growing older)
  • Prematurely graying hair
  • Autoimmune disorders such as type 1 diabetes, multiple sclerosis,rheumatoid arthritis, celiac disease, Addison's disease, perniciousanemia, or vitiligo
  • Bipolar disorder
  • Down syndrome
  • Turner syndrome
