sometimes if someone gets a digestive tract bacterial infection called c-diff the person needs to have a poop transplant in order to get rid of the c-diff and restore normal flora/bacteria into the digestive tract. you'd think that a poop transplant would involve taking poop from one person's butt and putting it up the butt of the other, but you'd be wrong. they liquify the donor's poop and then feed it to you through a nasal tube to the stomach. then you have to digest that poop. and you know how if you take omega 3/fish oil pills and you burp up the fish taste after you take them? if you get this poop transplant, you burp up poop taste for like two days or something. this is all true medicine.
