Patients who undergo weight loss surgery complain of gastrointestinal problems, study finds

Laparoscopic gastric bypass is an effective treatment for obesity, but a new study finds that patients who undergo the surgery often complain of gastrointestinal problems.

The study included 249 obese patients who underwent the surgery and 295 obese controls, all of whom completed a questionnaire. Surgical patients completed the questionnaire two years after surgery.

Surgical patients often experienced indigestion. Also, food intolerance, especially for food with a high fat or sugar content and for red meat, was a common side-effect of the surgery: food intolerance for specific products was reported by 70.7 per cent of postoperative patients compared with 16.9 percent of controls.

"Most studies in weight loss surgery focus on the short-term effects of surgery, and there was limited knowledge about the effect of a gastric bypass on gastrointestinal complaints in the long term," said Dr. Thomas Boerlage, lead author of the British Journal of Surgery study. "With this study, physicians can better counsel their patients, both before and after surgery. It also helps patients considering a gastric bypass to make a more well-thought decision.

    New study?  Give me a break.  I had gastric bypass surgery in 2003 and knew full well  back then that I would have food intolerance for the rest of my life for sugary food (it's called dumping syndrome, look it up), high fat foods and tough red meat.  I have found that I can only eat a perfectly cooked (meaning rare) filet mignon when it comes to steak (oh the horror!) and I avoid the sugary and high fat foods that got me in the position where I needed bypass surgery in the first place.  Isn't that one of the biggest reasons to having this type of surgery?  It was for me!  I was also warned about possibly developing GERD and having to have my gall bladder out (which I did), so this should is also not anything new.  These are all no brainers and if anyone complains, they either had very poor preparation for the surgery or didn't listen.  However, one thing I learned after the fact is that I can NEVER take NSAIDS like ibuprofen for the rest of my life for any length of time.  This study came out in 2007/2008 so I was not informed when I had my surgery.  Upon getting a tooth ache, I took ibuprofen for a weekend and ended up in the hospital with an ulcer which I am still healing from 2 months later.  Now THAT is news worth writing about, not this bs about food intolerance.
