How large are most colonoscopes?

This question was asked in Santa Barbara, California on 03/02/2012.
My general physician keeps telling me that I need to get a colonoscopy but I am afraid because of how uncomfortable it is. I am just most scared about the colonoscope and how uncomfortable that might be. How big in diameter are colonoscopes that are used for colonoscopy? I forgot to ask my doctor and keep finding different information.

The standard colonoscope is 13mm in diameter and 200cm in length. It will cause no trauma and you will be sedated for the procedure.
