Due to the course of events many of the consultations date back weeks and months and I have not received any written statements. I actually remember walking into the office(s) saying "I think I have a gut flora disorder."
So then I would think it would be a good idea (that can't hurt either way) that you consult a physician (or two, or more= different opinions) as soon as possible, describing all your symptoms to them, and, that you assume it started after the colonoscopy. I would deliberately leave out (your assumption, it seems=) that it "might be a gut flora disorder", in order to not prime them. Make a list of all your symptoms as detailed as possible (leaving out your inferences about "what it means/is") and bring it with you when you go to the docs.
Then report back here what they have said and/or discovered. Could very well be that it is something else or that the docs notice something you didn't take into account.
