Binge eating disorder is an eating disorder characterized by the need to excessively consume food in a period of food consumption (binge eating/binging) without the desire to purge.


In binge eating disorder, a patient will have recurrent episodes of binge eating without purges.

This is defined as, within 2 hour period, eating an amount of food that is definitely larger than what most people would eat in a similar period of time.

It must occur at least once a week for 3 months.

There are varying degrees of binge eating:

  • Mild (1-3 per week), moderate (4-7), severe (8-13), extreme (14+ per week)
  • Symptom: gaining weight (of course)
  • Prevalent in both males and females, 1.6%
