What is anorexia?

Anorexia is a type of eating disorder. People who have anorexia usually have a very low body weight because of an intense fear of gaining weight. They may not eat enough food because of this fear. Some people with anorexia make themselves vomit to avoid weight gain. Sometimes they exercise too much. They may have a false belief about how they look (distorted body image). And they may not realize how serious their low body weight is. If not treated, it can lead to serious health problems, starvation, and even death.

Anyone can have anorexia. It usually starts in the teen years. The earlier the problem is treated, the better the chances are that someone with anorexia can recover.

What causes it?

Experts don't really know what causes anorexia. But it may be due to a mix of genetics, family behaviors, social factors, and personality traits. For example, you may be more likely to have anorexia if someone in your family has it or if you do a sport that stresses body size, like gymnastics.

What are the symptoms?

People who have anorexia usually have a very low body weight for their age and height. Because they're very afraid of gaining weight, they may not eat enough food. They may have a false belief about how they look. They may not realize how serious their low body weight is.

How is it diagnosed?

Your doctor will ask questions about your eating habits. This is to see if you have the main symptoms of anorexia. If your doctor thinks you may have anorexia, they'll compare your weight with the expected weight for someone of your height and age. They will also check for signs of malnutrition or starvation.

How is anorexia treated?

You may work with a doctor, a dietitian, Opens dialog, and a counselor. Treatment can help you get back to a healthy weight, learn healthier eating habits, and learn to feel better about yourself. If your weight has dropped too low, you'll need treatment in a hospital.

What should you do if you think someone has an eating disorder?

If you think your child has an eating disorder:

  • Talk to them. Tell your child why you're worried. Let them know you care.
  • Make an appointment for you and your child to meet with a doctor or a counselor.

If you're worried about someone you know:

  • Tell someone who can make a difference, like a parent, a teacher, a counselor, or a doctor. A person with an eating disorder may say that they are okay and don't need help. You can help by encouraging them to talk to someone they trust.
