One thing that has struck me over the last 10 years or so (this is a good 8 years before I had any overt GI pain) is how many MORE foods cause me gas. I was actually a vegetarian for 5 years about a decade ago, but gradually I couldn't eat broccoli and other cruciferous vegetables, then I couldn't eat any stone fruits, like nectarines, then it was apples, and even fresh BASIL! And don't even bring a bowl of hummus, one of my old favorites, into the room with me! Seems like this has got to indicate either a change in digestive enzymes, a change in gut flora, or both. But WHY, and is it related to my current pain condition, that only began 14 some months ago? Another thing I've noted (and talk about embarrassing) is that I REALLY have to "bear down" these days to pass gas. Makes it MUCH more troublesome. I wonder if anyone else has noted any of these things?
