How alcohol affects people after weight-loss (bariatric) surgery
Pharmacokinetics and Responses to Alcohol After Bariatric Surgery
This project looks at how people's bodies process alcohol and how alcohol makes them feel after sleeve gastrectomy or gastric bypass surgery.

What this research studies
You would join a team that enrolls adults who have had sleeve gastrectomy (SG) or Roux-en-Y gastric bypass (RYGB) and gives controlled amounts of alcohol while taking repeated blood samples. The researchers will measure peak blood alcohol levels, how quickly alcohol is cleared, and ask how intoxicated you feel. They will also compare drinking with and without a meal to see if food still reduces alcohol absorption after surgery. The approach is meant to explain why these surgeries raise the risk of alcohol problems and to guide safer drinking advice.
Who could benefit from this research
Good fit: Ideal candidates are adults who have had sleeve gastrectomy or Roux-en-Y gastric bypass and who drink alcohol or are willing to drink small, supervised amounts for testing.
Not a fit: People who have never had bariatric surgery, minors, or those who do not drink alcohol are unlikely to benefit directly from this project.
Why it matters
Potential benefit: If successful, this work could give people who had bariatric surgery clearer, evidence-based guidance to lower their risk of alcohol-related harm and addiction.
How similar studies have performed: Prior studies, including the team's earlier NIH-funded work, have already shown SG and RYGB can double peak blood alcohol levels and increase alcohol sensitivity, so this builds on established findings.
