Definition
Disorders that fulfil some of the features of bulimia nervosa, but in which the overall clinical picture does not justify that diagnosis. For instance, there may be recurrent bouts of overeating and overuse of purgatives without significant weight change, or the typical overconcern about body shape and weight may be absent.
F50.3 in national editions
Countries report with their own edition of ICD-10. Most keep the WHO code and add more specific codes beneath it.
