Alcohol Consumption in Obese Patients Before and After Gastric Bypass as Assessed with the Alcohol Marker Phosphatidylethanol (PEth)

ConclusionsSeveral physiological changes postoperatively have to be considered when interpreting PEth results in obese patients with dramatic weight reductions. According to results for PEth, obese patients treated with bariatric surgery would seem to have lower alcohol consumption compared with the reference group. Although slightly increasing their PEth values postoperatively, the RYGB patients did not reach the PEth values of the reference group.
