Binge eating is a pattern of disordered eating which consists of episodes of uncontrollable eating. It is sometimes as a symptom of binge eating disorder. During such binges, a person rapidly consumes an excessive amount of food. Most people who have eating binges try to hide this behaviour from others, and often feel ashamed about being overweight or depressed about their overeating. Eating binges can be followed by so-called compensatory behaviour, acts by which the person tries to compensate for the effects of overeating. Examples of such acts are purging (induced vomiting or laxative abuse), fasting, and heavy exercising.
Although people who do not have any eating disorder may occasionally experience episodes of overeating, frequent binge eating is often a symptom of an eating disorder. Binge eating is a central feature of bulimia nervosa and binge eating disorder. It is also practiced by some people with an eating disorder not otherwise specified or anorexia nervosa.
A 2009 study of female rats concluded that binge eating of sweet-fat food alters opioid receptor in the nucleus of the solitary tract.
