Overview

Causes

The most common cause of hypothyroidism is thyroiditis. Swelling and inflammation damage the thyroid gland's cells.

Causes of this problem include:

  • The immune system attacking the thyroid gland
  • Viral infections (common cold) or other respiratory infections
  • Pregnancy (often called postpartum thyroiditis)

Other causes of hypothyroidism include:

  • Certain medicines, such as lithium and amiodarone
  • Congenital (birth) defects
  • Radiation treatments to the neck or brain to treat different cancers
  • Radioactive iodine used to treat an overactive thyroid gland
  • Surgical removal of part or all of the thyroid gland
  • Sheehan syndrome, a condition that may occur in a woman who bleeds severely during pregnancy or childbirth and causes the destruction of the pituitary gland
  • Pituitary tumor or pituitary surgery
