I always appreciate your perspective Jorge. I'm coming to the same conclusion that changing the flora isn't the answer too, but rather an immune issue.
I don't think changing the colonic flora will get whatever microbe is in my small intestine out. There may be some mechanims it would help but I'm not aware of it.
I do think these fecal implants will help me over time in other ways - detoxification, avoidance of bowel cancer, things like that but not my small intestine overgrowth.
