Sheehan's syndrome is a condition that affects women who lose a life-threatening amount of blood or who have severe low blood pressure during or after childbirth. These factors can deprive your body of oxygen and can seriously damage vital tissues and organs. In the case of Sheehan's syndrome, the damage occurs to the pituitary gland — a small gland at the base of your brain.
Sheehan's syndrome causes the permanent underproduction of essential pituitary hormones (hypopituitarism). Also called postpartum hypopituitarism, Sheehan's syndrome is rare in industrialized nations. But it's still a major threat to women in developing countries.
Treatment of Sheehan's syndrome involves hormone replacement therapy.
