Problematic Alcohol Use and Associated Characteristics Following Bariatric Surgery

Area of Science:

• Bariatric surgery outcomes
• Addiction medicine
• Psychiatric comorbidity

Background:

• Roux-en-Y gastric bypass (RYGB) surgery is associated with problematic alcohol and substance use in a minority of patients.
• Limited research exists on the characteristics, drinking patterns, and risk factors within this specific patient group.

Purpose of the Study:

• To describe alcohol and substance use symptoms in adults with self-identified alcohol use problems post-bariatric surgery.
• To examine psychiatric comorbidity, changes in alcohol sensitivity, and alcohol use patterns before and after surgery.

Main Methods:

• 26 adult participants completed telephone interviews and self-report assessments (AUDIT, MAST, DAST) 1-4 years post-RYGB or sleeve gastrectomy.
• Standardized diagnostic interviews and validated screening tools were used to assess alcohol and substance use.

Main Results:

• All participants met criteria for problematic alcohol use, reporting increased alcohol sensitivity post-surgery.
• Significant psychiatric comorbidities were noted, particularly a history of major depression (45.5%).
• Approximately one-third developed new-onset alcohol use disorder (DSM-IV) post-surgery; drinking patterns were similar to pre-surgery heaviest use.

Conclusions:

• Findings underscore the need for enhanced pre- and postoperative prevention and intervention strategies for alcohol use after bariatric surgery.
• Further research is essential to identify specific risk factors for problematic alcohol use following RYGB and other bariatric procedures.
