Substance use disorders often appear alongside other medical or mental health disorders, also known as co-occurring disorders. The National Eating Disorder Association reports that about 50% of those struggling with an eating disorder also struggle with a substance use disorder, while 35% of those with substance use disorders also struggle with an eating disorder.

Both, eating disorders and substance use disorders, stem from many of the same common risk factors, including social influence, family history, genetics, and mental health conditions such as anxiety and depression. People with either eating disorders or substance use disorders also often display signs of compulsiveness, social isolation or suicidal ideation.

When seeking treatment for one disorder it is imperative that co-occurring disorders be properly and carefully addressed.
