A member asked:

Is flexible sigmascope painful without sedation?

A doctor has provided 1 answer

Lasts 3-5 minutes: Sigmoidoscopy involves insertion of a flexible tube into your rectum, advanced anywhere from 35 to 70 cm. Air is used to inflate the colon during this process. If awake, you may feel distension from the air & pressure of scope passage. Everyone's threshold for discomfort varies so some don't feel sigmoidoscopy as uncomfortable at all while others register much discomfort from the same stimuli.
