Risk factors

By Mayo Clinic staff

Certain situations and events might increase the risk of developing an eating disorder. These risk factors may include:

  • Being female. Girls and women are more likely to have bulimia than boys and men are.
  • Age. Bulimia often begins in late adolescence or early adulthood. Bulimia is more common in college students than in younger teens.
  • Family history. Eating disorders, such as bulimia, are more likely to occur in people who have parents or siblings who've had an eating disorder.
  • Dieting. People who lose weight are often reinforced by positive comments from others and by their changing appearance. This may cause some people to take dieting too far, leading to bulimia.
  • Family influences. People who feel less secure in their families, whose parents and siblings may be overly critical, or whose families tease them about their appearance are at higher risk of bulimia and other eating disorders.
  • Emotional disorders. People with depression, anxiety disorders and obsessive-compulsive disorder are more likely to have an eating disorder.
  • Sports, work and artistic activities. Athletes, actors and television personalities, dancers, and models are at higher risk of eating disorders, such as bulimia. Eating disorders are particularly common among ballerinas, gymnasts, runners and wrestlers. Coaches and parents may unwittingly contribute to eating disorders by encouraging young athletes to lose weight.
