Bulimia Nervosa

Bulimia nervosa is a serious, potentially life-threatening eating disorder characterized by a cycle of bingeing and compensatory behaviors such as self-induced vomiting designed to undo or compensate for the effects of binge eating.

Bulimia Nervosa has three primary symptoms:  

  • Regular intake of large amounts of food accompanied by a sense of loss of controlover eating behavior.
  • Regular use of inappropriate compensatory behaviors such as self-induced vomiting, laxative or diuretic abuse, fasting, and/or obsessive or compulsive exercise.
  • Extreme concern with body weight and shape.

Eating disorder specialists believe that the chance for recovery increases the earlier bulimia nervosa is detected. Therefore, it is important to be aware of some of the warning signs of bulimia nervosa.

Warning Signs of Bulimia Nervosa:

  • Evidence of binge eating, including disappearance of large amounts of food in short periods of time or the existence of wrappers and containers indicating the consumption of large amounts of food.
  • Evidence of purging behaviors, including frequent trips to the bathroom after meals, signs and/or smells of vomiting, presence of wrappers or packages of laxatives or diuretics.
  • Excessive, rigid exercise regimen--despite weather, fatigue, illness, or injury, the need to “burn off” calories taken in.
  • Unusual swelling of the cheeks or jaw area.
  • Calluses on the back of the hands and knuckles from self-induced vomiting.
  • Discoloration or staining of the teeth.
  • Creation of lifestyle schedules or rituals to make time for binge-and-purge sessions.
  • Withdrawal from usual friends and activities.
  • In general, behaviors and attitudes indicating that weight loss, dieting, and control of food are becoming primary concerns.

Health Consequences of Bulimia Nervosa:

Bulimia nervosa can be extremely harmful to the body. The recurrent binge-and-purge cycles can damage the entire digestive system and purge behaviors can lead to electrolyte and chemical imbalances in the body that affect the heart and other major organ functions. Some of the health consequences of bulimia nervosa include:

  • Electrolyte imbalances that can lead to irregular heartbeats and possibly heart failure and death. Electrolyte imbalance is caused by dehydration and loss of potassium and sodium from the body as a result of purging behaviors.
  • Inflammation and possible rupture of the esophagus from frequent vomiting.
  • Tooth decay and staining from stomach acids released during frequent vomiting.
  • Chronic irregular bowel movements and constipation as a result of laxative abuse.
  • Gastric rupture is an uncommon but possible side effect of binge eating.

About Bulimia Nervosa:

  • Bulimia nervosa affects 1-2% of adolescent and young adult women.
  • Approximately 80% of bulimia nervosa patients are female (Gidwani, 1997).
  • People struggling with bulimia nervosa usually appear to be of average body weight.
  • Many people struggling with bulimia nervosa recognize that their behaviors are unusual and perhaps dangerous to their health.
  • Bulimia nervosa is frequently associated with symptoms of depression and changes in social adjustment.
