How does our microbiome affect our health? Is it possible that a "poop transplant" could reverse autoimmune disease? While that sounds a little crazy, if you listen to this podcast, it might start to make sense. Right now, FMTs are being used in the United States to cure life-threatening C. difficile infections, where medication has failed. Internationally, clinics are doing research into FMTs in the treatment of autoimmune disease. Today, I'm interviewing Glenn Taylor, director of the Taymount Clinic in the UK. He describes the science behind the transplants. Then, we hear from two patients who have received the procedure: one for C. difficile and one for multiple sclerosis.
