Bulimia

Definition

Bulimia nervosa is an eating disorder. People who have bulimia are overly concerned with weight and body image. They eat large amounts of food (called binge eating) and use inappropriate means to rid their bodies of the food (called purging) or excessive calories. Purging may be done through vomiting, laxatives, or water pills. Excessive exercise or fasting may replace or be used along with purging. This cycle of binge eating and purging is used to prevent weight gain.

Causes

The exact cause of bulimia is unknown. Factors that may contribute to this condition include:

  • Cultural bias toward thinness
  • Psychological problems due to changes in the level of brain chemicals, such as depression
  • Emotional stress
  • Distorted self-image

Bulimia is more young women, especially between 11-20 years old. Other factors that may increase your chance of bulimia include:

  • History of obesity
  • Anxiety
  • Mood disorders
  • Family members who have had an eating disorder or mood disorder
  • Low self-esteem
  • Unhappiness with weight and size
  • Career in which physical appearance is important

Diagnosis

Bulemia may be suspected after a physical exam and medical history. Questions about your dietary and exercise habits may be asked.

Once bulimia is suspected, other tests may be done to determine if the bulimia has caused an imbalance in the blood or heart. Tests may include:

  • Blood tests—to look for chemical imbalances
  • Electrocardiogram (EKG)—to check for abnormal heart rhythms
  • Drug screening—to check for drug use
