  • Congenital (birth) defects
  • Radiation treatments to the neck or brain to treat different cancers
  • Surgical removal of a part or all of the thyroid gland
  • Sheehan syndrome, a condition which may occur in women while childbirth causing destruction of the pituitary gland due to heavy bleeding.
