Which are the symptoms of Sheehan Syndrome?

Sheehan syndrome is a form of hypopituitarism caused by ischemic necrosis of the pituitary gland following severe postpartum hemorrhage. The most common symptoms include the failure to lactate, secondary amenorrhea, and signs of progressive hormonal deficiencies, such as extreme fatigue, low blood pressure, and cold intolerance.

What are the primary symptoms of Sheehan syndrome?

Symptoms of Sheehan syndrome typically manifest when more than 75% of the pituitary gland has been destroyed. Because the pituitary controls multiple endocrine functions, the clinical presentation is often multisystemic. The earliest and most characteristic sign is the inability to produce breast milk (agalactia) or the cessation of lactation following a complicated delivery. Other common symptoms include:

• Secondary amenorrhea (absence of menstrual periods)


• Significant, unexplained fatigue and lethargy


• Hypotension (low blood pressure) and dizziness


• Loss of axillary and pubic hair


• Cold intolerance and inability to maintain body temperature

How do symptoms of Sheehan syndrome progress?

The progression of Sheehan syndrome is often insidious, meaning it can take months or even years after the initial obstetric event for a full diagnosis to be reached. Patients frequently report that they feel "off" or chronically exhausted long before a blood test reveals the underlying hormonal deficiencies. Severity varies significantly depending on the extent of the pituitary tissue damage; some women may experience partial hypopituitarism, while others face total pituitary failure.

What symptoms most impact quality of life?

For the 21 members of the DiseaseMaps community living with Sheehan syndrome, the most debilitating symptoms are often the profound mental fog, persistent fatigue, and the emotional toll of hormonal instability. These symptoms can severely limit daily functioning, making it difficult to care for children or maintain professional responsibilities.

When should you seek immediate medical attention?

You must seek emergency care if you experience symptoms of an adrenal crisis, which is a life-threatening complication of Sheehan syndrome. Warning signs include severe abdominal pain, vomiting, diarrhea, confusion, or a sudden, dangerous drop in blood pressure. If you suspect you have Sheehan syndrome, consult an endocrinologist to undergo a comprehensive hormonal panel.

Next steps

• Consult an endocrinologist to perform a full pituitary hormone stimulation test.


• Maintain a detailed symptom diary to help your doctor track hormonal fluctuations.


• Join the Sheehan syndrome community at DiseaseMaps.org to connect with others who understand your experience.


• Wear a medical alert bracelet indicating you have adrenal insufficiency.
