Fecal transplantation is usually performed with a colonoscopy
, and the prep for the procedure is the same as it is for a colonoscopy. You must clean out your colon beforehand, which involves eating no solid food the day before the procedure, and only drinking clear liquids. After midnight the night before, you fast completely. You’ll also take a laxative in liquid or pill form the night before and possibly the morning of the exam, or give yourself an enema the night before or the morning of the procedure. This is all to clean out your colon. Your doctor might also recommend that you stop taking certain medications before the procedure.
During the procedure, you’ll be given a sedative via a needle in your arm (IV) to make sure you’re comfortable. Once you’re sedated, your doctor will insert a tube (colonoscope) into your rectum and into your colon. As the tube is withdrawn, the donor stool is inserted through the tube into your colon. You’ll need to recover from the sedation medication before you go home, and you'll need someone to accompany you to the procedure and drive you home as well.
