Eating disorders are serious medical problems.
Anorexia nervosa, bulimia nervosa, and binge-eating disorder are all types of eating disorders.
Eating disorders frequently develop during adolescence or early adulthood, but can occur during childhood or later in adulthood. Females are more likely than males to develop an eating disorder.
A person with an eating disorder may start out just eating smaller or larger amounts of food, but at some point, their urge to eat less or more spirals out of control. Severe distress or concern about body weight or shape, or extreme efforts to manage weight or food intake, also may characterize an eating disorder.
Eating disorders are more than just a problem with food. Food is used to feel in control of other feelings that may seem overwhelming. For example, starving is a way for people with anorexia to feel more in control of their lives and to ease tension, anger, and anxiety. Purging and other behaviors to prevent weight gain are ways for people with bulimia to feel more in control of their lives and to ease stress and anxiety.
Cause of Eating Disorders
Although there is no single known cause of eating disorders, several things may contribute to the development of these disorders:
- Culture. In the United States extreme thinness is a social and cultural ideal, and women partially define themselves by how physically attractive they are.
- Personal characteristics. Feelings of helplessness, worthlessness, and poor self-image often accompany eating disorders.
- Other emotional disorders. Other mental health problems, like depression or anxiety, occur along with eating disorders.
- Stressful events or life changes. Things like starting a new school or job or being teased and traumatic events like rape can lead to the onset of eating disorders.
- Biology. Studies are being done to look at genes, hormones, and chemicals in the brain that may have an effect on the development of, and recovery from eating disorders.
- Families. Parents' attitudes about appearance and diet can affect their kids' attitudes. Also, if your mother or sister has bulimia, you are more likely to have it.
Other Conditions Associated with Eating Disorders
Eating disorders frequently coexist with other illnesses such as depression, substance abuse, or anxiety disorders. Other symptoms can become life-threatening if a person does not receive treatment, which is reflected by anorexia being associated with the highest mortality rate of any psychiatric disorder.
Treatment of Eating Disorders
Typical treatment goals include restoring adequate nutrition, bringing weight to a healthy level, reducing excessive exercise, and stopping binging and purging behaviors. Specific forms of psychotherapy, or talk therapy—including a family-based therapy called the Maudsley approach and cognitive behavioral approaches—have been shown to be useful for treating specific eating disorders. Evidence also suggests that antidepressant medications approved by the U.S. Food and Drug Administration may help for bulimia nervosa and also may be effective for treating co-occurring anxiety or depression for other eating disorders.
Treatment plans often are tailored to individual needs and may include one or more of the following:
- Individual, group, or family psychotherapy
- Medical care and monitoring
- Nutritional counseling
- Medications (for example, antidepressants).
Some patients also may need to be hospitalized to treat problems caused by malnutrition or to ensure they eat enough if they are very underweight. Complete recovery is possible.
