IMO, you really need to question the route this doctor is going in. An infection in your stomach is not IBS. If an infection in your stomach is what he is thinking then yes an upper endoscope is appropriate since your stomach is viewed with this type of test. I think that maybe he is taking these symptoms seperately and saying that the symptoms you listed (minus the swelling) are the cause of IBS and the swelling is caused by an infection. If you don't have any other symptoms that would suggest an inflammatory bowel disease (Crohn's, UC) then maybe he is thinking that a colonoscopy is not necessary (note: some docs dx on symptoms only). The main thing though is to ask him about
everything. I know its kind of hard to question doctors but its a total necessity. If they don't like it then you need to find another one, a good doc will always be
open to many questions and take the time to explain.
