Experts don't know for sure what causes someone to have an eating disorder such as anorexia, bulimia, or binge eating. But certain things put a person at greater risk for getting an eating disorder. Some of these things include:

• Having a family history of an eating disorder.
• Struggling with depression, anxiety, low self-esteem, or obsessive behaviors.
• Feeling a need to be perfect.
• Feeling social or cultural pressure about thinness or weight.
• Having a negative body image.
• Taking part in sports or activities that encourage thinness. Modeling and dance are examples.
• Having a history of physical or sexual abuse.

Having risk factors for it doesn't mean a person will get an eating disorder. But knowing some of the things that can add to the risk may help to see signs of an eating disorder early when it is easier to treat.
