Purging disorder

People with purging disorder have recurrent purging behaviours that are similar to those in bulimia nervosa (eg self-induced vomiting, laxative or diuretic abuse); however, this is not accompanied by regular binge eating. Subjective binge eating (perceived overeating of small or normal food portions) may be present.

Purging disorder is managed similarly to bulimia nervosa. Monitor patients for medical complications, notably dehydration and metabolic disturbances of purging behaviours. Use the same psychological treatment as for bulimia nervosa. For patients who have not responded to psychological treatment alone or if there is difficulty in accessing the treatment, specialists may use pharmacological treatment as recommended for binge eating disorder.
