Sheehan's syndrome (SS) is postpartum hypopituitarism caused by necrosis of the pituitary gland. The onset in most cases is several months or even years after the inciting delivery, so it is often unrecognized and not adequately treated. Because SS often evolves slowly, it is usually diagnosed late. We report a 47-year old woman with loss of consciousness. Fourteen years ago, she had postpartum hemorrhage with subsequent amenorrhea and failure to lactate. Laboratory investigation showed low blood sugar and serum sodium levels, amid normal cortisol and thyroid function tests. Magnetic resonance imaging (MRI) of the pituitary revealed an empty sella consistent with SS. The presentation of hypoglycemia and hyponatremia are less known complications of Sheehan's syndrome with only a few documented in case reports.
