What is bulimia nervosa?
Bulimia (say "boo-LEE-mee-uh") is a type of Reference eating disorder Opens New Window. People with bulimia will eat a large amount of food in a short time (binge). Then they will do something to get rid of the food (purge). They may vomit, exercise too much, or use medicines like laxatives.

What causes bulimia?
All eating disorders are complex problems, and experts do not really know what causes them. But they may be caused by a mix of family history, social factors, and personality traits. You may be more likely to have bulimia if:
- Other people in your family are obese or have an eating disorder.
- You have a job or do a sport that stresses body size, such as ballet, modeling, or gymnastics.
- You are the type of person who tries to be perfect all the time, never feels good enough, or worries a lot.
- You are dealing with stressful life events, such as divorce, moving to a new town or school, or losing a loved one.
Bulimia is most common in:
- Teens. Like other eating disorders, bulimia usually starts in the teen years. But it can start even earlier or in adulthood.
- Women. But boys and men have it too.
While bulimia often starts in the teen years, it usually lasts into adulthood and is a long-term disorder.
What are the symptoms?
People with bulimia:
- Binge on a regular basis. They eat large amounts of food in a short period of time, often over a couple of hours or less. During a binge, they feel out of control and feel unable to stop eating.
- Purge to get rid of the food and avoid weight gain. They may make themselves vomit, exercise very hard or for a long time, or misuse laxatives, Reference enemas Opens New Window, water pills (Reference diuretics Opens New Window), or other medicines.
- Base how they feel about themselves on how much they weigh and how they look.

How can you know if someone has bulimia?

- Often talks about dieting, weight, and body shape.
- Uses laxatives or diuretics often.
- Has teeth marks or calluses on the back of her hands or swollen cheeks or jaws. These are caused by making herself vomit.
How is it treated?
Bulimia can be treated with psychological counseling and sometimes medicines, such as antidepressants. The sooner treatment is started, the better. Getting treatment early can make recovery easier and prevent serious health problems.
By working with a counselor, a person with bulimia can learn to feel better about herself. She can learn to eat normally again and stop purging.
