A comprehensive substance abuse treatment facility began observing increased admissions who reported histories of bariatric surgeries. The present study examined what unique variables may pose risk for substance abuse among bariatric surgery candidates and what issues may affect prognosis or treatment outcome for those currently in substance abuse treatment. Participants completed a questionnaire and participated in a semi-structured interview. Results indicate that post-bariatric patients developed problematic substance use significantly later in life, during a time that is not normative of new development of substances; were significantly more likely to be diagnosed with alcohol use disorders; and reported a significantly poorer psychological quality of life; yet they did not report a greater total number of drinks per drinking day or total substances used, and did not endorse greater behavioral excess. Post-bariatric patients may be overrepresented in substance abuse treatment programs, and they may need tailored treatment to address their unique characteristics.
