(CNN) - According to a new study in the Journal of the American Medical Association, some people who get weight-loss surgery may end up with a higher tendency to abuse alcohol.
But the risk is only apparent two years after the procedure and only with one type of surgery.
Researchers looked at the drinking habits of more than 2,400 obese adults before and after weight-loss procedures.
They found the number of patients with an alcohol problem jumped more than 50 percent within two years.
The risk was twice as high among patients who underwent Roux-en-Y gastric bypass.
In that procedure, doctors create a pouch out of a small portion of stomach.
Then, they connect the pouch to the small intestine, bypassing most of the stomach and some intestine.
The lead author says that allows alcohol to enter the bloodstream more quickly.
So, some patients may have increased sensitivity to alcohol.
