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.

Signs and symptoms of Sheehan's syndrome typically appear slowly, after a period of months or even years. But sometimes — such as in a breast-feeding mother — problems may appear right away.
Signs and symptoms of Sheehan's syndrome occur because of the deficiencies of the various hormones the pituitary gland controls: thyroid, adrenal, breast milk production and menstrual function. Signs and symptoms include:
For many women, Sheehan's syndrome symptoms are nonspecific and often attributed to other things. Fatigue, for instance, goes hand in hand with being a new mother. You might not realize that you have Sheehan's syndrome until you need treatment for thyroid or adrenal insufficiency.
It's also possible to remain relatively symptom-free with Sheehan's syndrome depending on the extent of damage to the pituitary gland. Some women live for years not knowing that their pituitary isn't working properly. Then an extreme physical stressor, such as severe infection or surgery, triggers an adrenal crisis.

Although many problems can lead to low pituitary function, Sheehan's syndrome is caused by severe blood loss or extremely low blood pressure during or after childbirth. These factors can be particularly damaging to the pituitary gland, destroying hormone-producing tissue so that the gland can't function normally.
Pituitary hormones regulate the rest of your endocrine system, signaling other glands to increase or decrease production of the hormones that control metabolism, fertility, blood pressure, breast milk production and many other vital processes. A lack of any of these hormones can cause problems throughout your body — although signs and symptoms may develop so gradually that they escape notice.

Diagnosing Sheehan's syndrome can be difficult. Many of the symptoms overlap with those of other conditions. To diagnose Sheehan's, your doctor likely will:

Because pituitary hormones control so many aspects of your metabolism, Sheehan's syndrome can cause a number of problems, including:
The most serious complication is adrenal crisis, a sudden, life-threatening state that can lead to extremely low blood pressure, shock, coma and death.
Adrenal crisis usually occurs when your body is under marked stress — such as during surgery or a serious illness — and your adrenal glands produce too little cortisol, a powerful stress hormone.
Because of the potentially serious consequences of adrenal insufficiency, your doctor is likely to recommend that you wear a medical alert bracelet.

Any condition that increases the chance of severe blood loss (hemorrhage) or low blood pressure during childbirth, such as being pregnant with multiples or having a problem with the placenta, may increase your risk of Sheehan's syndrome.
Hemorrhage is a rare childbirth complication, however, and Sheehan's syndrome is even more uncommon. Both risks are greatly reduced with proper care and monitoring during labor and delivery.
