The Risk of Substance Use Among Adolescents and Adults With Eating Disorders.

Eating disorders (EDs) are negative eating habits that have harmful mental and physical effects. EDs primarily affect young women. Most cases are diagnosed in adolescence. The most common EDs are bulimia nervosa (BN), anorexia nervosa (AN), and binge eating disorder (BED). There is a strong association between EDs and substance use disorder (SUD) in adolescence. Bulimia nervosa and alcohol use disorder (AUD) are the most common co-occurrence. There is a high behavioral association between EDs and AUD. Alcohol consumption could be a primary trigger for binge eating in women with BN. Alcohol can be used as an appetite suppressor and as a compensatory behavior to avoid food. The objective of this literature review was to explore the relation between EDs and SUD. The results of the study showed SUD is common with EDs. There are many reasons for this association such as shared neurobiological mechanisms, personality features, environmental and genetic factors.
