Bulimia nervosa is defined by repeated episodes of binge eating followed by compensatory behaviours.
People with bulimia nervosa often place an excessive emphasis on body shape or weight in their self-evaluation. This can lead to the person’s sense of self-esteem and self-worth being defined by the way they look.
Binge eating involves two key features:
- Eating a very large amount of food within a relatively short period of time (e.g. within two hours)
- Feeling a sense of loss of control while eating (e.g. feeling unable to stop yourself from eating)
These behaviors are used as a way of trying to control weight after binge eating episodes. They include:
- Misusing laxatives or diuretics
- Excessive exercise
- Use of any drugs, illicit, prescription and/or ‘over the counter’ inappropriately for weight control (inappropriate use refers to use that is not indicated and for which the drug has not been prescribed)
A person with bulimia nervosa can become lost in a dangerous cycle of out of control eating and attempts to compensate which can lead to feelings of shame, guilt and disgust. These behaviors can become more compulsive and uncontrollable over time, and lead to an obsession with food, thoughts about eating (or not eating), weight loss, dieting and body image.
These behaviors are often concealed and people with bulimia can go to great lengths to keep their eating and exercise habits secret. As a result, bulimia can often go undetected for long periods of time.
Many people with bulimia nervosa experience weight fluctuations and do not lose weight; they can remain in the normal weight range, be slightly underweight, or may even gain weight.
