Sheehan syndrome

  • Definition
    • Sheehan syndrome is a condition that can occur in a woman who bleeds severely during childbirth. Sheehan syndrome is a type of hypopituitarism.

  • Alternative Names
    • Postpartum hypopituitarism; Postpartum pituitary insufficiency; Hypopituitarism Syndrome

  • Causes
    • Severe bleeding during childbirth can cause tissue in the pituitary gland to die. This gland does not work properly as a result.

      The pituitary gland is at the base of the brain. It makes hormones that stimulate growth, production of breast milk, reproductive functions, the thyroid, and the adrenal glands. A lack of these hormones can lead to a variety of symptoms.

      Conditions that increase the risk of bleeding during childbirth and Sheehan syndrome include multiple pregnancy (twins or triplets) and problems with the placenta. The placenta is the organ that develops during pregnancy to feed the fetus.

      Sheehan syndrome is very rare.

  • Symptoms
    • Symptoms of Sheehan syndrome may include:

      • Inability to breast-feed (breast milk never "comes in")
      • Fatigue
      • Lack of menstrual bleeding
      • Loss of pubic and axillary hair
      • Low blood pressure

      Note: Other than not being able to breast feed, symptoms may not develop for several years after the delivery.

  • Exams and Tests
    • Tests you may have include:

      • Blood tests to measure hormone levels
      • MRI of the head to rule out other pituitary problems, such as a tumor
  • Treatment
    • Treatment involves estrogen and progesterone hormone replacement therapy. These hormones must be taken at least until the normal age of menopause. Thyroid and adrenal hormones must also be taken. These will be needed for the rest of your life.

  • Outlook (Prognosis)
    • The outlook with early diagnosis and treatment is excellent.

  • Possible Complications
    • This condition can be life threatening if not treated.

  • Prevention
    • Extreme bleeding during childbirth can often be prevented by proper medical care. Otherwise, Sheehan syndrome is not preventable.
