Patients with anorexia nervosa have fewer gastrointestinal complications than those with bulimia nervosa. Constipation is common. In addition, these patients still have prolonged gastrointestinal transit, alterations in antral motility, and gastric atrophy. Prokinetic agents may accelerate gastric emptying, and the relief from gastric bloating can accelerate resumption of normal eating habits.
