Binge eating is an eating disorder in which a person regularly eats unusually large amounts of food.
During binge eating, the person also feels a loss of control and is not able to stop eating. Unlike bulimia nervosa, periods of binge-eating are not followed by purging, excessive exercise, or fasting. As a result, people with binge-eating disorder often are overweight or obese. Binge-eating disorder is the most common eating disorder in the U.S.
Eating disorders frequently appear during the teen years or young adulthood but may also develop during childhood or later in life. These disorders affect both genders, although rates among women are 2½ times greater than among men. Like women who have eating disorders, men also have a distorted sense of body image. For example, men may have muscle dysmorphia, a type of disorder marked by an extreme concern with becoming more muscular.
Researchers are finding that eating disorders are caused by a complex interaction of genetic, biological, behavioral, psychological, and social factors. Researchers are using the latest technology and science to better understand eating disorders.
One approach involves the study of human genes. Eating disorders run in families. Researchers are working to identify DNA variations that are linked to the increased risk of developing eating disorders.
Brain imaging studies are also providing a better understanding of eating disorders. For example, researchers have found differences in patterns of brain activity in women with eating disorders in comparison with healthy women. This kind of research can help guide the development of new means of diagnosis and treatment of eating disorders.
The exact cause of binge eating is unknown.
Things that may lead to this disorder include:
- Genes, such as having close relatives who also have an eating disorder
- Changes in brain chemicals
- Depression or other emotions, such as feeling upset or stressed
- Unhealthy dieting, such as not eating enough nutritious food or skipping meals
In the United States, binge eating is the most common eating disorder. More women than men have it. Women are affected as young adults while men are affected in middle age.
- Eating unusually large amounts of food in a specific amount of time
- Eating even when you're full or not hungry
- Eating fast during binge episodes
- Eating until you're uncomfortably full
- Eating alone or in secret to avoid embarrassment
- Feeling distressed, ashamed, or guilty about your eating
- Frequently dieting, possibly without weight loss
Adequate nutrition, reducing excessive exercise, and stopping purging behaviors are the foundations of treatment.
Treatment plans are tailored to individual needs and may include one or more of the following:
- Individual, group, and/or family psychotherapy
- Medical care and monitoring
- Nutritional counseling
Psychotherapies such as a family-based therapy called the Maudsley approach, where parents of adolescents with anorexia nervosa assume responsibility for feeding their child, appear to be very effective in helping people gain weight and improve eating habits and moods.
To reduce or eliminate binge-eating and purging behaviors, people may undergo cognitive behavioral therapy (CBT), which is another type of psychotherapy that helps a person learn how to identify distorted or unhelpful thinking patterns and recognize and change inaccurate beliefs.
