It's a subject even some doctors find off-putting, but for patients with gastrointestinal ailments, like severe irritable bowel syndrome and bacterial infections, a lifesaving surgery is all they have. We're talking about fecal transplant surgery. It's exactly what it sounds like. Surgeons take the feces from a donor, typically a spouse or relative though it could be anyone, and put it in another. Jerry Grant, a 33-year-old man suffering from Clostridium difficile, which disabling and even life-threatening diarrhea, nausea, vomiting and abdominal pain, was more than happy to bend over and have his wife's poop put up his butt. Sheesh, he's was in so much pain that he would eat the feces if it would bring relief.
