Because researchers only recently began studying
binge-eating disorder, they're still trying to learn
more about potential causes.
As with other mental
disorders, there's likely no single cause. Rather, binge-eating
disorder probably arises from an interplay of biological,
psychological and sociocultural factors, including family,
relationships and life experiences.
Here's a closer look:
Biological
Some people may be
biologically vulnerable to developing binge-eating disorder.
Both genes and brain chemicals may be involved in the disorder.
In addition, researchers are studying appetite regulation of the
central nervous system for clues, along with gastrointestinal
changes that might shed light on causes.
Psychological
People with
binge-eating disorder may have psychological and emotional
characteristics that contribute to the disease. They may have
low self-worth, for instance. They may have trouble controlling
impulsive behaviours, managing their moods or expressing anger.
Socio-Cultural
Modern Western
culture often cultivates and reinforces a desire for thinness.
Although most people who have binge-eating disorder are
overweight, they're acutely aware of their body shape and
appearance and berate themselves after eating binges. Some
people with binge-eating disorder have a history of being
sexually abused.
