Criteria for feeding and eating disorders from the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5)

Diagnosis	DSM-5 diagnostic criteria
Anorexia Nervosa (AN)	Restriction of energy intake leading to a significantly low body weight, intense fear of gaining weight, disturbance in the way in which one's body weight is experienced, denial of the seriousness of the current low body weight. Two subtypes: restricting type: (no binge eating or purging in the last 3 mo) and binge eating/purging type (binge eating or purging in the last 3 mo)
Bulimia Nervosa (BN)	Recurrent episodes of binge eating (eating a large amount of food in a discrete period of time with sense of lack of control) with compensatory behavior to prevent weight gain (e.g., vomiting, laxatives, diuretics, fasting, and excessive exercise) at least once a week for 3 mo. Self-evaluation is unduly influenced by body weight
Binge Eating Disorder (BED)	Recurrent episodes of binge eating that are associated with 3 (or more) of: eating rapidly, eating until uncomfortably full, eating large amounts when not hungry, eating alone because of being embarrassed, and guilt/disgust after overeating. Occurs at least once a week for 3 mo with absence of compensatory behaviors
Avoidant/Restrictive Food Intake Disorder (ARFID)	A feeding disturbance (e.g., lack of interest in food; sensory avoidance of food; and concern about consequences of eating) as manifested by failure to meet nutritional needs associated with 1 (or more) of: significant weight loss or faltering growth, nutritional deficiency, dependence on nutritional supplements, and interference with psychosocial functioning. Not better explained by lack of available food or by cultural practice. No evidence of body weight disturbance. Not better explained by another medical condition or if so, is severe enough to warrant additional clinical attention
Rumination disorder	Repeated regurgitation of food for a period of ≥1 mo. Regurgitated food may be rechewed, reswallowed, or spit out. Not better explained by another medical condition or if so, is severe enough to warrant additional clinical attention
Pica	Persistent eating of non-nutritive, nonfood substances for ≥1 mo that is inappropriate to the developmental level of the individual and is not part of a cultural or social practice. If occurring in the context of another condition, it is sufficiently severe to warrant additional clinical attention
Other Specified Feeding or Eating Disorder (OSFED)	Examples of presentations that can be specified using OSFED: •Atypical anorexia nervosa: all AN criteria are met, except despite significant weight loss, the individual’s weight is within or above the normal range •Bulimia nervosa (of low-frequency and/or limited duration): all of the criteria for BN are met, except that episodes occurs at a lower frequency and/or for <3 mo •Binge eating disorder (BED) (of low-frequency and/or limited duration): all of the criteria for BED are met, except at a lower frequency and/or for <3 mo •Purging disorder: recurrent purging behavior to influence weight or shape in the absence of binge eating •Night eating syndrome (NES): recurrent episodes of night eating: eating after awakening from sleep, or excessive eating after the evening meal that causes significant distress/impairment. The behavior is not better explained by environmental influences, social norms, or by another disorder (e.g., BED)
