Alcohol consumption patterns up to 10 years after bariatric surgery: using the highly specific biomarker phosphatidylethanol

Alcohol consumption, as measured by PEth, increased significantly after bariatric surgery, particularly in men. These findings support routine postoperative alcohol screening and suggest incorporating PEth testing into long-term follow-up protocols.
