Eating disorders — physical risks
Anorexia nervosa: bradycardia, hypotension, hypothermia, orthostatic changes, lanugo, amenorrhea, osteoporosis. Cardiac complications are the leading cause of death. Bulimia and purging: hypokalemia, metabolic alkalosis, dental erosion, parotid swelling, esophageal tears. Refeeding syndrome: phosphate, potassium and magnesium fall sharply when nutrition restarts too fast. Risk of arrhythmia, heart failure and seizures. Advance calories slowly and check electrolytes daily during the first week.
