Planning for Upper Endoscopy Next Week

At Jason's GI appointment last month she scheduled him for an upper endoscopy. I've been talking with the hospital and such getting the final details all smoothed out. What worries me most about this procedure is the need for general anesthesia to get into the esophagus and get pictures and biopsies. Children, anyone for that matter, shouldn't have to do something like this on a regular basis. Jason of course has been a trooper from the day we started poking and proding him looking for answers. He's a tough little guy. The hardest thing for him right now is that I've restricted his diet completely. No cheating with a little corn syrup here and there. Corn is one of his foods he's allergic to. But the allergist says he should be able to eat corn syrup because it shouldn't have that many proteins in it. If you look at the corn syrup industry, they say that yes, there is a little corn protein in it, but it shouldn't bother anyone. Though they don't understand that for some people even the smallest amount could put them in the hospital. We're lucky... Jason doesn't seem to be affected by corn syrup. However, I want to ensure a 100% clear scope next week! If it comes back showing eosinophils in his esophagus, I'll be completely stumped as to why, except for maybe wheat. So you can understand me wanting to make things as simple and understandable as possible. All Jason wants is a lollipop!
