Why is colonoscopy painful?

I am going to schedule my first colonoscopy. I am very worried about the pain. How painful will the colonoscopy be? What is the main cause of the pain?

With a safe amount of medications, colonoscopy is only mildly uncomfortable. The air that is put in will cause some mild discomfort but will pass shortly.

Depending on your overall health you may be sedated during a colonoscopy making it painless. Some patients also are not sedated and have no pain. Please talk with your gastroenterology doctor about your concerns. Thanks.
