Module 1 - Types of Eating Disorders 5

Diagnostic Criteria: OTHER SPECIFIED FEEDING AND EATING DISORDER

• This category applies when symptoms of eating disorders that cause clinically significant distress or impairment in social, occupational, or other important areas of functioning predominate but DO NOT MEET FULL CRITERIA for any of the other eating disorder categories. Examples of presentations in this category may included:
• 1. Atypical anorexia nervosa: All of the criteria for anorexia nervosa are met, except that despite significant weight loss, the individual's weight is within or above the normal range (eg. if someone started out overweight and lost a significant amount of weight, and met other criteria for AN).
• 2. Bulimia nervosa (of low frequency and/ or limited duration): All of the criteria for BN are met, except that binge eating and inappropriate compensatory behaviours occur, on average, less than once per week and/ or for less than 3 months duration.
• 3. Binge eating disorder (of low frequency and/ or limited duration): All of the criteria for BED are met, except that binge eating occurs, on average, less than once per week and/ or for less than 3 months duration.
• 4. Purging Disorder: Recurrent purging behavior to influence weight or shape (e.g. self induced vomiting; misuse of laxatives, diuretics, or other medications) in the absence of binge eating.
