Chronic Sheehan's Syndrome - A Differential to be Considered in Clinical Practice in Women with a History of Postpartum Hemorrhage.

Sheehan's syndrome is hypopituitarism due to pituitary gland necrosis resulting from hemorrhagic shock during pregnancy. It is a rare complication with varied manifestations and a considerable delay in diagnosis. We describe the case of a 36-year-old female with eight years of non-specific symptoms of generalized myalgias and intense fatigue managed symptomatically all these years. Further clinical assessment revealed amenorrhea and agalactia ongoing for several years without a clinical diagnosis. A good history and physical led to the diagnosis during a routine outpatient visit. She had significant improvement noted following the commencement of treatment. Previous case reports describe cases being diagnosed after one or other complications from long-term panhypopituitarism. Through this case, we want to illustrate that undiagnosed Sheehan's syndrome is associated with long-term morbidity, and there should be a high index of suspicion for it to be diagnosed during a routine clinical visit and thus prevent complications before a diagnosis can be made. It is essential to create awareness, especially in developed countries like the United States, where it has received less attention over the last few years.
