I was diagnosed with IBS more than ten years ago after having a colonoscopy. Then, in 2009, my gastroenterologist diagnosed collagenous colitis after another colonoscopy. In late September 2014, after having several stool samples tested, I was diagnosed with Pancreatic Insufficiency Elastace. I am now taking prescription Creon digestive enzymes every time I eat anything. I'm interested in learning if anyone else on this Forum has been diagnosed with PIE? I'm also following the IBS Diet which has helped my condition significantly. I welcome anyone's thoughts.
