I went to a new G.I today and he wants to do an Upper Endoscopy despite my *not* having any heartburn, burping, bleeding, nausea, etc. or otherwise issues. I suffer from IBS and have had a colonoscopy in my past which showed nothing negative.I'm wondering what an Upper Endoscopy would show, since I don't have the usual symptoms that it would be done for. I'm also wondering if my doctor is suggesting this merely because he wants to make a buck. I'd like not to come to the later conclusion.My insurance doesn't cover procedures, so I want to be sure that this is necessary and a good idea before I shell out $3000 for it.Thanks.
