Eating disorders can be treated and a healthy weight can be restored. The sooner these disorders are diagnosed and treated, the better the outcomes are likely to be. Because of their complexity, eating disorders require a comprehensive treatment plan involving medical care and monitoring, professional interventions, nutritional counseling and, when appropriate, medication management.
Treatment of anorexia calls for a specific program that involves three main phases: restoring the person to a healthy weight lost to severe dieting and purging; treating psychological disturbances such as distortion of body image, low self-esteem, and interpersonal conflicts; and reducing or eliminating behaviors or thoughts that lead to disordered eating, and preventing relapse.
Some research suggests that the use of medications, such as antidepressants, antipsychotics or mood stabilizers, may be modestly effective in treating patients with anorexia by helping to resolve mood and anxiety symptoms that often co-exist with anorexia. Recent studies, however, have suggested that antidepressants may not be effective in preventing some patients with anorexia from relapsing. In addition, no medication has shown to be effective during the critical first phase of restoring a patient to healthy weight. Overall, it is unclear if and how medications can help patients conquer anorexia, but research is ongoing.
Different forms of psychotherapy, including individual, group and family-based, can help address the psychological reasons for anorexia nervosa. Some studies suggest that family-based therapies in which parents assume responsibility for feeding their afflicted adolescent are the most effective in helping a person with anorexia gain weight and improve eating habits and moods. Others have noted that a combined approach of medical attention and supportive psychotherapy designed specifically for anorexia patients is more effective than just psychotherapy. But the effectiveness of a treatment depends on the person involved and her situation.
Hospital based care (including inpatient, partial hospitalization, intensive outpatient and/or residential care in an eating disorders specialty unit or facility) is necessary when an eating disorder has led to physical problems that may be life-threatening, or when it is associated with severe psychological or behavioral problems.
The course and outcome of anorexia nervosa vary across individuals: some fully recover after a single episode; some fluctuate between weight gain and relapse; and others chronically deteriorate over many years. The mortality rate among people with anorexia has been estimated at .56 percent per year which is about 12 times higher than the annual death rate due to all causes of death among females ages 15-24 in the general population. The most common causes of death are complications of the disorder, such as cardiac arrest or electrolyte imbalance, and suicide.
The primary goal of treatment for bulimia is to reduce or eliminate binge-eating and purging behavior. Nutritional rehabilitation, professional intervention and medication management are often employed. As with anorexia, treatment for bulimia often involves a combination of options and depends on the needs of the individual.
To reduce or eliminate binge and purge behavior, a patient may undergo nutritional counseling and psychotherapy, especially cognitive behavioral therapy (CBT), or be prescribed medication. Some antidepressants, such as fluoxetine (Prozac), which is the only medication approved by the FDA for treating bulimia, may help patients who also have depression and/or anxiety. It also appears to help reduce binge-eating and purging behavior, reduces the chance of relapse, and improves eating attitudes. CBT that has been tailored to treat bulimia also has shown to be effective in changing binging and purging behavior, and eating attitudes. Therapy may be individually oriented or group-based.
The treatment goals and strategies for binge-eating disorder are similar to those for bulimia. Fluoxetine and other antidepressants may reduce binge-eating episodes and help alleviate depression in some patients. Patients with binge-eating disorder also may be prescribed appetite suppressants. Psychotherapy, especially CBT, is also used to treat the underlying psychological issues associated with binge-eating, in an individual or group environment.
People with eating disorders often do not recognize or admit that they are ill. As a result, they may strongly resist getting and staying in treatment. Family members or other trusted individuals can be helpful in ensuring that the person with an eating disorder receives needed care and rehabilitation.
