Key points

  • Bulimia nervosa is an eating disorder where a person has a distorted body image and a fear of gaining weight.
  • The disorder involves both binge eating (eating much more than most people would in a short period of time and feeling guilty or ashamed) and purging (self-induced vomiting, taking laxatives, diuretics, weight loss pills, fasting, or exercising) to try to prevent weight gain.
  • It is important to see a health-care provider if you experience episodes of binge eating or purging, or you think you might have bulimia nervosa or another eating disorder.
