Binge eating is a pattern of disordered eating which consists of episodes of uncontrollable eating. It is a common symptom of eating disorders such as binge eating disorder and bulimia nervosa. During such binges, a person rapidly consumes an excessive quantity of food. A diagnosis of binge eating is associated with feelings of loss of control. Binge eating disorder is also linked with being overweight and obesity.
The DSM-5 includes a disorder diagnosis criterion for Binge Eating Disorder (BED). It is as follows:
Recurrent and persistent episodes of binge eating
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 physically hungry
Eating alone because of being embarrassed by how much one is eating
Feeling disgusted with oneself, depressed, or very guilty after overeating
Marked distress regarding binge eating
Absence of regular compensatory behaviors (such as purging)
Typical warning signs of binge eating disorder include the disappearance of a large quantity of food in a relatively short period of time. A person who may be experiencing binge eating disorder may appear to be uncomfortable when eating around others or in public. A person may develop new and extreme eating patterns that they have never done before. These might include diets that cut out certain food groups completely such as a no dairy or no carb diet. Binge eating can begin before a first attempt at dieting. They might also steal or hoard food in unusual places. A person may be experiencing fluctuations in their weight. In addition, they may have feelings of disgust, depression, or guilt about overeating. Another possible warning sign of binge eating is that a person may be obsessed with their body image or weight.
Furthermore, patients who binge eat may also engage in other self-destructing behaviours like suicide attempts, drug use, shop-lifting, and drinking too much alcohol.

Anorexia nervosa (AN), often referred to simply as anorexia, is an eating disorder characterized by low weight, food restriction, , fear of gaining weight, and an overpowering desire to be thin. Individuals with anorexia nervosa have a fear of being overweight or being seen as such, although they are in fact underweight. The DSM-5 describes this perceptual symptom as "disturbance in the way in which one's body weight or shape is experienced". In research and clinical settings, this symptom is called "body image disturbance".
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.
Night eating syndrome (NES) is an eating disorder, characterized by a delayed circadian pattern of food intake. Although there is some degree of comorbidity with binge eating disorder, it differs from binge eating in that the amount of food consumed in the night is not necessarily objectively large nor is a loss of control over food intake required. It was originally described by Albert Stunkard in 1955 and is currently included in the other specified feeding or eating disorder category of the DSM-5.
