Diagnostic Criteria for Bulimia Nervosa


Updated July 11, 2013

Written or reviewed by a board-certified physician. See About.com's Medical Review Board.

The Diagnostic & Statistical Manual of Mental Disorders, fifth edition, (DSM-V) is published by the American Psychiatric Association. It provides physicians and mental-health professionals with the criteria for diagnosing specific mental disorders, including bulimia nervosa.

A person must meet all of the DSM criteria to be diagnosed with bulimia nervosa:

  • Repeated episodes of binge eating. An episode of binge eating is defined as eating "an amount of food that is definitely larger than most people would eat" during the same amount of time. The person also must feel as though they have lost control over eating and are unable to stop themselves or control how much they are eating.

  • Using inappropriate behaviors to avoid weight gain or to compensate for the binge eating. Professionals often refer to these behaviors as "compensatory behaviors." They include self-induced vomiting, the misuse of laxatives, diuretics and/or enemas, and excessive exercise.

  • Both the binge eating and compensatory behaviors occur at least once a week for three months.

  • The person's weight and/or body shape has a significant impact on the way the person views himself or herself.

The DSM-V also allows professionals to specify whether or not someone is in partial or full remission (recovery) and how severe their disorder is. The levels of severity are based on how frequently someone experiences episodes of binge eating and compensatory behaviors as well as how much the disorder affects their day-to-day life.

If you or someone you know is suffering from some or all of the above criteria it is important that he or she see a physician, dietician or mental-health professional for an assessment.
