president obama's decision to let young illegal immigrants stay in america. good evening, i'm terry moran. every year, more than 200,000 americans undergo weight loss surgery. for most, the procedure is life-saving, literally. but this kind of surgery works dramatic changes to the body and it can cause many unexpected effects. today, a new study suggests a startling link between gastric bypass and increased odds of alcohol addiction. so are patients getting thin only to become alcoholic? here's abc's deborah roberts. >> reporter: youtube is full of confessions of people who dropped weight from gastric bypass surgery and then found themselves drinking heavily. >> i'd start and pour myself a glass of wine, finish it, and

then more. >> when i woke up, i was still pretty drunk. >> you have to have an addictive personality to really become a morbidly obese person. >> reporter: singer wilson was drinking up to ten martinis a day. >> i was getting drunk very fast and i was getting sober very fast. and it was frightening. it was frightening. >> reporter: andrew kahn knows that feeling, after his bypass, he, too, found himself losing control to alcohol. >> i started drinking, and it was the first time in my life i was drinking heavily that i thought i didn't have control over myself. >> reporter: now, a new study out today that may offer explanation. according to the journal of the american medical association more than 1 in 10 gastric bypass patients have become alcoholics after two years after the surgery. >> essentially what a gastric

bypass does to alcohol is similar to what people who snort drugs would get into their bloodstream. >> reporter: that's because the stomach is shrunk to roughly the size of an egg, limiting the body's ability to absorb calorie eyes. that also includes alcohol. so patients both feel the effects of alcohol and also sober up quickly. >> one drink which may not have had any effect on you, may have a very, very big effect on you following a gastric bypass. >> reporter: for many, life after weight loss surgery can be a troubling reality. >> my weight loss surgery was entirely done in vanity. >> reporter: in 2006, beth had her stomach reduced and went from 320 pounds to 160, half her weight. her husband had it, too, and lost 200 pounds but after the high of losing weight quickly, she began feeling let down, frustrated and regretful. >> every day you get up again

and think i'm going to get on the scale again and it just -- you ride it. >> reporter: what happens when the honeymoon ends? >> well, you're married. you're married to the surgery. and not all marriages work. >> reporter: beth began blogging and soon realized her feelings post surgery were common. what else do you hear from people that surprises you about this weight loss surgery? >> addiction. >> reporter: addiction other than food? >> when it's over and you can no longer use it as your crutch, you've almost got to find something to fill that missing space where food was. alcohol is rampant in our community. >> reporter: so alcohol becomes the addiction because it's easier to digest than food. >> if you can't swallow chicken, you can swallow wine. >> reporter: now, they're attributing it to something called addiction transference. that's always been a controversial theory. today, study adds new fuel to

the debate. >> i think it has to do with the fact that alcohol which is already an addictive drug becomes more addictive when we alter your anatomy. >> reporter: more complicated that weight loss is emerging as the most effective way of combatting obesity. it can be life-saving. >> there is no more effective procedure in medicine, they go into complete reverse of diabetes before they've lost any weight. >> reporter: bariatric surgeons say follow up with patients monitoring is key but hasn't always been a priority. >> in the early days, we probably didn't have the connection that we have now. >> is that the biggest feeling in weight-loss surgery, the lack of emotional support? >> any surgeon can take care of us here, but nobody touches this. >> reporter: still beth like so many others she talks with online says even knowing the

risks, she'd do it all over again. do you regret or are you mostly happy with this decision? >> i'm a success. it worked. the surgery did what it was supposed to do. >> reporter: for "nightline," i'll deborah roberts in new york. >> a fascinating and important link, thanks to deborah roberts for that. up next, you seldom know what to expect when you're expecting. now, we meet some real life trophy husbands.
