• Anorexia nervosa is characterized by body image distortion and fear of gaining weight despite an abnormally low BMI.

• Clinical eating disorders and disordered eating can disrupt almost all major organ systems. Medical complications due to malnutrition include bradycardia, hypotension, amenorrhea, edema, and osteoporosis (low bone mineral density).
