Bulimia Nervosa

Overview

Definition

Bulimia is an eating disorder. People with bulimia are overly worried about their weight and body image. They binge and purge their food. Bingeing is eating large amounts of food. Purging is using vomiting, laxatives, or diuretics to get it out of the body. Exercise may be used to replace purging, or it may be used with it. The cycle is done to stop weight gain.

Causes

The cause is not known. It may be due to a mix of genes and the environment.

Risk Factors

Bulimia is more common in young women. Other things that may raise the risk are:

  • Low self-esteem
  • Feelings of helplessness
  • Wanting to be perfect
  • Fear of gaining weight
  • Not being happy with weight and size
  • Pressure to be thin
  • Having other family members with the same problems
  • Emotional stress
  • Prior obesity or anorexia
  • Having other mental health problems, such as depression or anxiety
  • Substance use disorder
  • A way of life that highlights being thin as ideal
