I had the FMT after being very ill for 4 months. I failed Flagyl, vancomycin & Dificid. It’s been 2 weeks. I had mine through an endoscopy that my dr went past the stomach into the small intestine so that it would be past the stomach acid. I’m still not far enough out to know if it has worked. I sure hope it does. I’m down to 85 pounds & need to get well. I had to try it. I was out of options.
