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. Signs and symptoms
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.
Up to 70% of individuals with BED may also be obese, and therefore obesity-associated morbidities such as high blood pressure and coronary artery disease type 2 diabetes mellitus gastrointestinal issues (e.g., gallbladder disease), high cholesterol levels, musculoskeletal problems and obstructive sleep apnea may also be present. Epidemiology
General
The prevalence of BED in the general population is approximately 1-3%.BED cases usually occur between the ages of 12.4 and 24.7, but prevalence rates increase until the age of 40.Binge eating disorder is the most common eating disorder in adults.The limited amount of research that has been done on BED shows that rates of binge eating disorder are fairly comparable among men and women. The lifetime prevalence of binge eating disorder has been observed in studies to be 2.0 percent for men and 3.5 percent for women, higher than that of the commonly recognized eating disorders anorexia nervosa and bulimia nervosa. However another systematic literature review found the prevalence average to be about 2.3% in women and about 0.3% in men. Lifetime prevalence rates for BED in women can range anywhere from 1.5 to 6 times higher than in men. One literature review found that point prevalence rates for BED vary from 0.1 percent to 24.1 percent depending on the sample. This same review also found that the 12-month prevalence rates vary between 0.1 percent to 8.8 percent.Recent studies found that eating disorders which included anorexia nervosa, bulimia nervosa and binge-eating disorder are common among sexual and gender minority populations, including gay, lesbian, bisexual and transgender people.
