Criteria for Diagnosing Bulimia Nervosa

  • Repeated episodes of binge eating with an associated sense of loss of control over eating during the episode.
  • Repeated use of inappropriate behaviors to prevent weight gain or to reverse it, such as:
    • Self-induced vomiting
    • Misuse of laxatives, diet pills, or diuretics (water pills)
    • Fasting
    • Excessive exercise
  • Both binge eating and inappropriate behaviors occur at least two times per week for at least three months.
  • Self-esteem is overly influenced by weight or shape.
  • Not meeting the criteria for anorexia nervosa.


Subtypes of Bulimia Nervosa

  • Purging: engaging in self-induced vomiting or misusing diet pills, laxatives, or diuretics to compensate for the effects of binge eating
  • Nonpurging: fasting or excessive exercise to compensate for the effects of binge eating
