Alcohol and the Bariatric Patient: When One Drink Becomes Two Drinks Moderate consumption of alcohol is a risk factor for weight gain and obesity. Alcohol affects all components of the energy balance. Alcohol consumption is - as in the general population - also a widespread phenomenon in obese and bariatric patients. As a function of the bariatric surgery technique, alcohol metabolism is altered: gastric bypass surgery and sleeve gastrectomy lead to a faster absorption of alcohol, higher peak alcohol concentration and a longer alcohol persistence in the circulation. Further reward mechanisms for alcohol are changed, so that alcohol consumption is enhanced and promoted, with an increased risk to develop alcohol dependency. It is time to address these issues in the daily practice and to fill the existing research gaps.
