What is Bulimia?

Bulimia Nervosa is an eating disorder characterized by bingeing and purging. People diagnosed with bulimia frequently binge on food, eating thousands of calories in a single episode. Feelings of shame and disgust often accompany these binge eating episodes, leading to purging behaviors such as vomiting, laxative abuse, over-exercising and/or fasting. This compensatory behavior is a tell-tale sign that an individual is suffering from bulimia. Despite attempts to lose weight by purging, those with bulimia generally maintain a body weight that is normal or slightly above average.

According to the DSM-5, the following criteria must be met for an individual to be diagnosed with bulimia (please note that if all of the following are not met, an individual may still have a serious eating disorder that requires treatment):

  1. Recurrent episodes of binge eating. An episode of binge eating is characterized by both of the following:
    1. Eating, within a two- hour window, an amount of food that is definitely larger than what most people would eat during a similar period of time and under similar circumstances.
    2. Lack of control over eating during the episode (e.g., a feeling that you cannot stop eating or control how much you are eating).
  1. Recurrent inappropriate compensatory behavior to prevent weight gain, such as self-induced vomiting, misuse of laxatives, diuretics, or other medications, fasting, or excessive exercise.
  2. The binge eating and inappropriate compensatory behaviors both occur, on average, at least once a week for three months.
  3. Self-evaluation is unduly influenced by body shape and weight.
  4. Binging or purging does not occur exclusively during episodes of behavior that would be common in those with anorexia nervosa.
