Eating disorders, in particular
bulimia nervosa and
binge eating disorder are associated with co-morbid alcohol and
drug abuse. School-based studies have shown significant associations between bulimic behaviors and various measures of alcohol, cigarette and other
drug use and abuse. Amongst bulimic adolescents,
substance use is related to an increased likeliness of high risk behaviors such as attempted suicide, stealing and sexual intercourse. In contrast with bulimics and binge eaters, restricting anorexics have low rates of co-morbid
substance abuse. It appears that restricting anorexics, binge eaters and bulimics represent distinct subgroups within the eating disordered population and binge eaters and bulimics are more prone to alcohol use. It is possible that individuals with
eating disorders turn to alcohol use/abuse as a way of coping with the problems caused by their
eating disorder. Researchers have proposed that an addictive personality is an underlying trait, which predisposes individuals to both
eating disorders and
alcohol abuse.
Eating disorders are often conceptualized as an addictive disorder.
Opioid antagonists, such as
naltrexone, may be useful in treating both eating and
alcohol use disorders. There is also evidence that
serotonin reuptake inhibitors, which are traditionally used to treat major depression, may be an effective treatment. Cognitive-behavioral therapy has been effective in treating alcohol use and
eating disorders individually and may be an effective combined treatment for co-morbid
eating disorders and alcohol use. Teaching healthy ways to cope with the stressful situations may also help decrease alcohol use and disordered eating behaviors.
