Bulimia Nervosa

Bulimia nervosa is an eating disorder. People who have bulimia eat very large amounts of food (called binging) and many also use inappropriate means (vomiting, laxatives, water pills) to rid their bodies of the food (called purging). Affected individuals eat compulsively, then purge to prevent gaining weight. They are overly concerned with weight and body image. In some individuals excessive exercise or fasting may replace or supplement purging.

The cause of bulimia nervosa is unknown. Several factors may contribute to this condition:

  • Cultural bias toward thinness
  • Dieting or restricted eating
  • Changes in the level of brain chemicals
  • Emotional stress
  • Physical changes in the digestive system, including:
    • An enlarged stomach
    • A stomach that empties slowly
    • Decreased production of a digestive hormone
Risk Factors:
A risk factor is something that increases your chance of getting a disease or condition.

  • Stained or chipped teeth, due to contact with stomach acid
  • Cuts or scars on back of hands, from scraping skin on teeth during forced vomiting

Bulimia may lead to other problems, including:

  • Dental and throat problems from stomach acid that rises during vomiting

Symptoms of these complications include:

  • Dizziness
  • Feeling faint
  • Thirst

People with bulimia have a high incidence of personality disorder and of treatable psychiatric conditions, including:

  • Anxiety and panic disorder
  • Drug and alcohol abuse or dependence
The doctor will ask about:
  • Your medical and psychological history
  • The amount of food you eat
  • The ways you to try to rid your body of food

The doctor will also perform a physical exam and check your teeth for signs of erosion.

Tests may include:

Blood Tests – to look for chemical imbalances

Electrocardiogram (ECG or EKG) – to look for heart problems due to purging

Drug Screening - to check for drug use

A mental-health professional may also perform a psychiatric exam and/or psychological tests.

The goals of treatment are:

  • To stop binging and purging
  • To focus self-esteem away from body weight and shape

Treatments include:

A type of therapy known as Cognitive Behavioral Therapy can be very effective in eliminating or reducing binging and purging. Cognitive behavioral therapy may be particularly effective when combined with drug treatment.

Other therapies may be less effective, but can help patients:

  • Gain insight into the problem
  • Recognize what triggers binging and purging
  • Develop new coping skills
  • Learn and practice stress-management techniques
  • Talk about feelings
  • Develop a more appropriate idea of thinness
  • Develop healthier attitudes about eating
  • Learn to eat regularly to reduce the urge to binge

Antidepressant drugs, particularly “selective serotonin reuptake inhibitors – SSRIs” have proven effectiveness in helping reduce binging and purging behaviors.

Please Note: On March 22, 2004, the Food and Drug Administration (FDA) issued a Public Health Advisory that cautions physicians, patients, families and caregivers of patients with depression to closely monitor both adults and children receiving certain antidepressant medications. The FDA is concerned about the possibility of worsening depression and/or the emergence of suicidal thoughts, especially among children and adolescents at the beginning of treatment, or when there is an increase or decrease in the dose. The medications of concern ­- mostly SSRIs (Selective Serotonin Re-uptake Inhibitors) - are: Prozac (fluoxetine), Zoloft (sertraline), Paxil (paroxetine), Luvox (fluvoxamine), Celexa (citalopram); Lexapro (escitalopram), Wellbutrin (bupropion), Effexor (venlafaxine), Serzone (nefazodone), and Remeron (mirtazapine). Of these, only Prozac (fluoxetine) is approved for use in children and adolescents for the treatment of major depressive disorder. Prozac (fluoxetine), Zoloft (sertraline), and Luvox (fluvoxamine) are approved for use in children and adolescents for the treatment of obsessive compulsive disorder.
