TORONTO Adults who have a common type of bariatric surgery to lose weight have a significantly higher risk of developing alcohol abuse problems in the second year following their operations, a large study suggests.

Researchers found that patients who had the Roux-en-Y procedure -- in which a small stomach pouch is created and connected to the middle of the small intestine -- had a higher prevalence of problems with alcohol consumption compared to the year before surgery and the year immediately after.

"We found that seven per cent of Roux-en-Y gastric bypass patients reported symptoms of alcohol use disorder (AUD) in the year prior to surgery," said lead author Wendy King, an epidemiologist at the University of Pittsburgh.

That percentage didn't change much in the first year following surgery. But by Year 2, almost 11 per cent of patients were reporting potentially problematic changes in their alcohol consumption, King said from San Diego, where she was presenting the findings at a meeting of the American Society for Metabolic and Bariatric Surgery.

"Among patients who had laparoscopic adjustable gastric banding, we did not find a significant difference," said King, referring to the procedure in which a band is placed around the upper stomach to reduce the amount of food that can be ingested.

To conduct the study, researchers assessed alcohol consumption patterns in 1,945 bariatric surgery patients at 10 hospitals across the United States. Within 30 days before surgery, and again one and two years after their operations, patients completed an audit to identify symptoms of alcohol use disorders, a condition that includes alcohol abuse and dependence.

Participants were categorized as having AUD if they had at least one symptom of alcohol dependence, including not being able to stop drinking once started, or alcohol-related harm, such as not being able to remember a certain event.

About 70 per cent of participants had Roux-en-Y surgery; another 25 per cent had lap banding, while the other five per cent had less common weight-loss surgical procedures.

Overall, one in eight participants reported having at least three drinks on a typical drinking day the second year after surgery. Another one in eight said they had at least six drinks on one occasion.
