When you're "bleeding rectally for weeks on end, you don't have any choice but to think you're dying," Grant told KPNX 12 News in Arizona. Grant's gut had been taken over by Clostridium difficile (known as C. diff), and wiped out all the other good bacteria.
C. diff causes abdominal pain, bleeding and severe diarrhea, up to 10 or 15 times a day, according to the Mayo Clinic.
Grant couldn't even sit down because it hurt too much, and he and his wife spent thousands of dollars on treatments that just didn't work, 12 News reported.
But finally, the cure came in a very unusual, but notoriously effective, method: to transfer some of his wife's fecal matter (poop), into his own colon, in order to restore his natural balance of bacteria, a process known also as fecal microbiota therapy. The Mayo Clinic in Scottsdale, Ariz., administered the fecal transplant.
