This woman was being treated for recurrent Clostridium difficile, not obesity. The weight gain was a side affect of the treatment, not the reason for it. Yes, people recently have started experimenting with fecal transplants to help with weight loss, but that's not what was happening here. The woman also picked her daughter because who wants a stranger's poop injected into their colon? No one... is pretty much the correct answer there. No one. Lastly, this was done in 2011, so... up the butt it went.
