Acute Sheehan's Syndrome Associated with Postpartum Hemorrhage

Sheehan's syndrome is postpartum hypopituitarism due to the necrosis of the pituitary gland. Usually, it is the result of severe hypotension caused by massive hemorrhage during or after delivery. A 40-year-old woman who had been performed cesarean section delivery was complicated by hemorrhage due to uterine atony. After transfusion and hysterectomy, she is gradually recovering her general condition. On 16th day after operation, she visited emergency room in critical condition with nausea, vomiting, and general weakness and laboratory finding was hyponatremia. So, we medicated her with hydrocortisone and thyroxine. Sheehan's syndrome should be considered in the differential diagnosis of hyponatremia in the early postpartum period.
