Highlights:

Eating Disorders Overview

• Eating disorders typically occur among young women.
• Bulimia nervosa involves a pattern of bingeing and purging. Many people with bulimia nervosa also suffer from depression.
• Anorexia nervosa involves a pattern of self-starvation. Patients often have an accompanying anxiety disorder (such as obsessive compulsive disorder) or depression. Patients who have anorexia and depression have a high risk for suicide.

Complications of Bulimia Nervosa

Many medical problems are directly associated with bulimic behavior, including:

• Tooth erosion, cavities, and gum problems
• Water retention, swelling, and abdominal bloating
• Acute stomach distress
• Low potassium levels
• Irregular menstrual periods
• Swallowing problems and esophagus damage

Complications of Anorexia Nervosa

Anorexia nervosa can increase the risk for serious health problems such as:

• Hormonal changes, including reproductive, thyroid, stress, and growth hormones
• Heart problems such as abnormal heart rhythm
• Electrolyte imbalance
• Fertility problems
• Bone density loss
• Anemia
• Neurological problems

Treatment of Bulimia Nervosa

• Bulimia nervosa is treated with a combination of psychotherapy and medication.
• Cognitive behavioral therapy, which is given along with nutritional counseling, is the preferred psychotherapeutic approach.
• Selective serotonin reuptake inhibitors (SSRIs), such as fluoxetine (Prozac), are the first choice for drug therapy.

Treatment of Anorexia Nervosa

• Unlike bulimia nervosa, anorexia nervosa does not respond as well to drug treatment, although SSRIs are sometimes used as an adjunct to psychotherapy.
• Therapy that includes the entire family -- not just the patient -- is an important part of the treatment process, as is nutritional education.
• Patients who are severely underweight and who have other physical risks may need to be hospitalized while weight is restored. Recovery is a long process that can take 5 - 6 years to achieve.
