Sheehan's syndrome is a rare complication of pregnancy with multiple hormone deficiency. The exact pathogenetic mechanism is not well understood, because such endocrine abnormalities are not obvious in most women with severe hemorrhage. Central diabetes insipidus with fluid and sodium disturbances occurred in about 5% of the patients. [1,2] There are very few existing literature discussing concomitant Sheehan's syndrome and acute renal failure. The following case reports a patient showing Sheehan's syndrome, irreversible acute renal failure and central diabetes insipidus concurrently.
