Understanding Binge-Eating Disorder

Learn about binge-eating disorder

While overeating every now and then may not be harmful, people with binge-eating disorder have extreme difficulty stopping themselves from eating large quantities of food on a regular basis. Their difficulties with stopping themselves from eating are not a matter of willpower, but are instead more akin to an obsessive-compulsive disorder. Unlike with bulimia, people with binge-eating disorder do not feel compelled to vomit or use laxatives to rid their bodies of the extra calories they have consumed. Although binge-eating disorder can have profound and dangerous negative effects in a person’s life, when treatment for the symptoms of the disorder is sought, the potential for further consequences can often be managed.


Binge-eating disorder statistics

In a given year, slightly over 1 percent of people are diagnosed with binge-eating disorder in the United States. Over the course of their lives, slightly less than 3 percent of people will struggle with a binge-eating disorder, with 3.5 percent of females and 2 percent of males being diagnosed. Unfortunately, only about 44 percent of individuals diagnosed with binge-eating disorder receive treatment over the course of their lives.

Causes and Risk Factors

Causes and risk factors for binge-eating disorder

Although the causes of binge-eating disorder are not fully understood, research suggests that a number of genetic and environmental factors come into play, including the following:

Genetic: As with most mental health conditions, family history has an influence on who is more likely to develop binge-eating disorder. People with family members who have eating disorders are more likely themselves to develop eating disorders.

Environmental: Research on epigenetics suggests that environmental factors can “switch on” certain genes. While the precise interaction of environment and genetics is still a topic of research, experts have found that certain environmental factors do correlate with an increased chance of developing an eating disorder. People who grew up in families with parents who encouraged extreme dieting or unhealthy eating habits are more likely to develop binge-eating disorder, as are those who were teased about their weight.

Risk Factors:

  • Having poor self-esteem
  • Being dissatisfied with one’s own skills and/or accomplishments
  • Personal history of extreme dieting
  • Age, specifically being in one’s late teens or early 20s
  • Family history of mental illness
  • Personal history mental illness
