Binge eating disorder
Summary
Binge eating disorder (BED) is an eating disorder characterized by frequent and recurrent binge eating episodes with associated negative psychological and social problems, but without the compensatory behaviors common to bulimia nervosa, OSFED, or the binge-purge subtype of anorexia nervosa.
BED is a recently described condition, which was required to distinguish binge eating similar to that seen in bulimia nervosa but without characteristic purging. Individuals who are diagnosed with bulimia nervosa and binge eating disorder exhibit similar patterns of compulsive overeating, neurobiological features of dysfunctional cognitive control and food addiction, and biological and environmental risk factors. Some professionals consider BED to be a milder form of bulimia with the two conditions on the same spectrum.
Binge eating is one of the most prevalent eating disorders among adults, though there tends to be less media coverage and research about the disorder in comparison to anorexia nervosa and bulimia nervosa.
Binge eating is the core symptom of BED; however, not everyone who binge eats has BED. An individual may occasionally binge eat without experiencing many of the negative physical, psychological, or social effects of BED. This may be considered disordered eating rather than a clinical disorder. Precisely defining binge eating can be problematic, however, binge eating episodes in BED are generally described as having the following potential features:
Eating much faster than normal, perhaps in a short space of time
Eating until feeling uncomfortably full
Eating a large amount when not hungry
Subjective loss of control over how much or what is eaten
Planning and allocating specific times for binging
Eating alone or secretly
Not being able to remember what was eaten after the binge
Feelings of guilt, shame or disgust following a food binge
In contrast to bulimia nervosa, binge eating episodes are not regularly followed by activities intended to compensate for the amount of food consumed, such as self-induced vomiting, laxative or enema misuse, or strenuous exercise.
