Binge eating disorder (BED) is an eating disorder characterized by recurrent episodes of eating large quantities of food (often very quickly and to the point of discomfort); a feeling of a loss of control during the binge; experiencing shame, distress or guilt afterwards; and not regularly using unhealthy compensatory measures (e.g., purging) to counter the binge eating. Binge eating disorder is a severe, life-threatening and treatable eating disorder. Common aspects of BED include functional impairment, suicide risk and a high frequency of co-occurring psychiatric disorders.

BED Symptoms and Diagnostic Criteria

The DSM-5, published in 2013, lists the diagnostic criteria for binge eating disorder:

1. Recurrent episodes of binge eating. An episode of binge eating is characterized by both of the following:
   • Eating, in a discrete period of time (e.g., within any 2-hour period), an amount of food that is definitely larger than what most people would eat in a similar period of time under similar circumstances.
   • A sense of lack of control over eating during the episode (e.g., a feeling that one cannot stop eating or control what or how much one is eating).
2. The binge eating episodes are associated with three (or more) of the following:
   • Eating much more rapidly than normal.
   • Eating until feeling uncomfortably full.
   • Eating large amounts of food when not feeling physically hungry.
   • Eating alone because of feeling embarrassed by how much one is eating.
   • Feeling disgusted with oneself, depressed, or very guilty afterward.
3. Marked distress regarding binge eating is present.
4. The binge eating occurs, on average, at least once a week for 3 months.
5. The binge eating is not associated with the recurrent use of inappropriate compensatory behaviors (e.g., purging) as in bulimia nervosa and does not occur exclusively during the course of bulimia nervosa or anorexia nervosa.
