Hello I am seeing a very good Gastroenterologist in Australia for my severe intractable constipation. He has told me my best chance at recovery is Rifaxamin + Vancomycin followed with 10 days of FMT, with the first one via colonoscopy and the subsequent ones via rectal catheter. The first one via colonoscopy is very important because it gets to the very start of the colon which is important from their clinical experience. However i have severe sensitivities and i am very very worried of this procedure and i am not sure if i should do it. I can only imagine how i will react to the sedatives, as things like panadol give me vertigo, anxiety etc. What do you guys think?
