They do: Colonoscopy preparations are supposed to cause you to have significant diarrhea. Ideally you will be passing clear liquid in the end. So if you're passing yellow liquid I would encourage you to continue this until you are passing clear liquid. This will optimize the preparation and allow for the best visualization of the colon during the colonoscopy. Best of luck.

Colonoscopy prep: Ideal end result of colonoscopy prep is yellow to greenish clear fluid. So UR probably there & prep has been successful. Good luck with your colonoscopy.
