So I've spent hours today looking into all this stuff. (This may be TMI for you, but I leave it here in case it helps someone else.) I actually had a biopsy, but they took all their samples from above the duodenum, not in/below it. For gastroenteritis (stomach inflammation)/vomiting, it makes sense to take them above the duodenum. To make a ruling for coeliac (where it seems that food does not come back up, but apparently is more likely to go out the other end?), you have to take them in the duodenum. The results of my biopsy were positive for gastroenteritis, which just means you have stomach inflammation, but doesn't tell you anything about what's causing it. They thought it was from coffee/soda, but I now know that's not right, from personal experience with glutinous foods.
