Food intolerances two years after gastric bypass (PS - No, really?)

Apparently this concern with gastric bypass patients hasn't been "well-studied."

Hey researchers - PLEASE SEEK OUT PATIENTS WHOM COMPLAIN OF EXACTLY THESE ISSUES FROM DAY ONE.  

Because, uh, *putting on my Dr. Google Hat* they're totally normal and expected, or so we thought?  Or am I living under a rock where it's that we're not supposed to live with digestive distress most of the time?I suppose this is my bias because I live as a distressed patient, with a distressed patient, and know mostly only distressed patients?  And WHAT IS GOING ON WITH THE FOODS LISTED IN THIS STUDY!?

I am using a lot of question marks lately.  I need to stop that.

Discuss.

Study blurb via Reuters -

(Reuters Health) - A common weight loss surgery is associated with long-term gastrointestinal problems and food intolerance, a recent study suggests.

Researchers examined data on 249 extremely obese patients who had what’s known as laparoscopic Roux-en-Y gastric bypass, which reduces the stomach to a small pouch about the size of an egg.

Two years after surgery, these patients had lost about 31 percent of their total body weight on average. But compared to the control group of 295 obese people who didn’t have operations, the gastric bypass patients were far more likely to experience indigestion and an inability to tolerate multiple foods.

“It was already known from previous studies that the Roux-en-Y gastric bypass might aggravate gastrointestinal symptoms after surgery,” said lead study author Dr. Thomas Boerlage of MC Slotervaart in Amsterdam.
