Always dangerous: Depends on frequency/severity of bulimia. It causes electrolyte imbalances that may lead to heart failure, as well as esophageal and gastric ruptures, all of which may be fatal. Other medical complications for bulimia include bone loss, osteoporosis, dehydration, kidney disease, anemia and low white cell counts, which lowers the immune system and creates vulnerability to disease and infection.
