High-Risk Alcohol Use and Disordered Eating Behavior Before and 1 Year After Sleeve Gastrectomy

Abstract

Background: Evidence suggests a rise in alcohol misuse after some bariatric procedures. Whether undergoing sleeve gastrectomy raises the risk of high-risk alcohol use is unclear. Objective: To characterize the risk of high-risk alcohol use 1 year after sleeve gastrectomy and collect preliminary data on potential associations between disordered eating and high-risk drinking post-surgery. Methods: We interviewed 97 patients before and 1 year after sleeve gastrectomy and assessed for high-risk alcohol use via a modified version of the Alcohol Use Disorders Identification Test-Consumption (AUDIT-C). Eating behavior was assessed using the Three Factor Eating Questionnaire Revised-18 (TFEQ-R18). Results: The prevalence of high-risk drinking increased from 13.4% prior to surgery to 22.7% 1 year after sleeve gastrectomy; 16.5% of our sample reported new high-risk drinking equivalent to an incidence of 19.0%. New high-risk drinkers appeared more likely to report lower cognitive restraint scores and higher scores for emotional and uncontrolled eating at baseline and had larger improvements in disordered eating scores post-surgery although these differences approached, but did not reach, statistical significance. Conclusion: One in five non-high-risk drinkers developed new high-risk alcohol intake 1 year after sleeve gastrectomy. New high-risk drinkers appear to have greater disordered eating at baseline and reported greater improvement in eating behavior than those who did not develop new high-risk drinking. These results are consistent with the addiction transfer hypothesis postulating that some patients may replace disordered eating with alcohol misuse after sleeve gastrectomy.
