Well, your GI is wrong or you misinterpreted what he said about
Infliximab not stopping the inflammation. It doesn't stop the
root cause of inflammation, but it certainly interrupts the inflammatory process at some stage. At the moment, researchers don't even know what the root cause of Crohn's is, let alone how to stop it. The root cause is probably determined by a combination of genetic, immunological and environmental factors in most people. There isn't a med or diet in the world which can currently stop Crohn's at the root cause, or, to put it another way, 'cure' Crohn's.
All the business about
gut flora, it's just a theory so far. What
are the 'bad' bacteria in Crohn's, for example? Nobody knows, apart from MAP, and even that's controversial and far from commonly accepted.
But if you wanna follow that line of reasoning, then there are GIs who treat Crohn's as a bacterial infection and treat it accordingly. I recommend looking up Thomas Borody, an Australian gastroenterologist who has developed a protocol for eliminating MAP, a bacterium long suspected of causing Crohn's disease in humans (it causes a similar disease in cows).
If you don't mind reading, here's a paper by Borody:
www.scirp.org/Journal/PaperInformation.aspx?paperid=19619From what I've heard and seen on his website, he still treats most Crohn's patients the 'conventional' way, but uses his anti-MAP protocol for severe or non-responsive cases.
