Binge eating disorder (BED) is characterized by episodes of uncontrollable consumption of large amounts of food in a discrete amount of time associated with a subjective sense of lack of control overeating. Unlike bulimia nervosa, BED is not associated with concurrent weight loss behaviors such as self-induced vomiting, excessive exercise, or the use of laxatives or diuretics.


The incidence of BED among women between 10 and 24 years of age was 35 per 100,000 person-years.

  • Lifetime prevalence of BED in the United States and Western Europe of 1–3%
  • Occurs in about 2–5% of the adult population
  • More common in females than males
  • 17–30% of individuals with BED have normal body weights.
  • An estimated 1–2% of adolescents have BED.
  • Mean age of onset for BED is 23.3 years.
  • BED is seen in between 5% and 50% of patients seeking treatment for obesity. The severity of the psychopathy is not related to BMI.

Etiology and Pathophysiology

  • Patients with BED likely have dysregulation of motivation of impulse control similar to that seen in other impulsive and compulsive disorders.
  • Changes in dopaminergic and opioidergic neurotransmitter networks are associated with binge eating behaviors.
  • Neuroimaging studies show corticostriatal circuitry changes in BED similar to those seen in substance abuse.

  • BED has a familial heritability from 41% to 57%.
  • BED has been shown to aggregate in families independent of obesity status.
  • Specific dopamine receptor genetic polymorphisms have been associated with individuals with BED.

Risk Factors

  • BED is associated with obesity and with risk factors for psychiatric disorders.
  • BED is associated with obesity and may confer the risk of components of metabolic syndrome.

General Prevention

Well-established risk factors for eating disorders, including BED, include an elevated perceived pressure to be thin, internalization of the thin-ideal standard of female beauty, body mass, body dissatisfaction, and negative affectivity.

Commonly Associated Conditions

  • 30–80% of individuals with BED have lifetime comorbid mood or anxiety disorders.
  • BED even below the threshold of BED is associated with suicidality. The relationship between BED and suicidality is much stronger in women relative to men.
  • Other psychiatric comorbidities and personality disorders reported in individuals with BED or eating disorders include gambling problems, bipolar disorder, substance abuse, and avoidant, obsessive-compulsive disorder, and borderline personality disorders.
