Fecal transplants are one of the hottest areas of new medical research, as scientists have come to understand the role the microbiome — the billions of bacteria that live in and on the body — plays in health.
Though researchers are still trying to understand how the microbiome works, evidence has been mounting that the makeup of the microbiome affects the body’s immune system. Hence scientists have been studying whether fecal transplants can help with immune disorders like Crohn’s disease and ulcerative colitis, particularly in children. See my story in WebMD.
