Having an empty bowel before your
colonoscopy will help ensure an accurate test result. The process of cleansing the bowels, in addition to fasting, before your procedure is known as "
bowel prep."
Using a laxative such as
colyte® (
polyethylene glycol electrolyte solution) the night before your colonoscopy will help prepare the bowels by emptying them out completely. This will allow your healthcare provider to have a better image of your
colon, since any stool remaining in the colon can block important findings.
It normally takes about one hour after you start drinking the solution to have your first bowel movement. Loose bowel movements will continue for one to two hours after your last dose.
