[Sheehan's syndrome: a recurrent obstetrical complication].

Case report of a 25-year-old primigravida who sustained a necrosis of the anterior pituitary gland after a haemorrhagic Caesarean section. The diagnosis was delayed, as the early symptoms (apathy, anorexia, nausea, orthostatic hypotension and hypoglycaemia) were imputed to more usual causes.
