Physiological Characteristics and Medical Complications Anorexic and Bulimic clients are at risk of serious medical consequences. Consequences range from gastrointestinal distress to death. The mortality rate for anorexia is roughly 10 percent. Although most individuals with eating disorders endeavor to present a facade of good health, the severity and variety of their physical ailments tell an alarmingly different story. Bulimic sufferers with extreme purging by laxatives or vomiting may show obvious electrolyte imbalance in lab work. Those with anorexia may yield somewhat normal blood lab values, only to later have sudden failure of the heart or another organ of the body.
