BREW ME Model: How bariatric surgery changes alcohol use biology

Official title: Biobehavioral Mechanistic Model of Alcohol Use Following Bariatric Surgery: The BREW ME Model

Funded at Sanford Research North · NIH-11408840 · Data updated 2026-11-12

Who could benefit from this research

Could help

People who have undergone or will undergo bariatric surgery and are at risk for problematic alcohol use.

Less likely to help

Patients not at risk for alcohol problems after bariatric surgery or those not pursuing bariatric options may have limited direct benefit.

What this research studies

After bariatric surgery, weight loss is often excellent, but some patients unexpectedly develop risky drinking patterns. This project looks at how the gut microbiome and brain reward systems interact to influence alcohol use after surgery. It combines behavioral data with biological measures to map the pathways linking bariatric procedures to alcohol-related behaviors. The goal is to identify targets that could help prevent hazardous drinking while preserving the benefits of surgery.

Why it matters

Potential benefit: If successful, this work could lead to better screening and interventions to reduce post-surgery alcohol problems.

How similar studies have gone: Previous work shows links between microbiome changes and reward processing, but the BREW ME Model seeks a comprehensive mechanistic map specific to post-surgical alcohol use.
