My doctor told me I need to get a colonoscopy, what should I expect?

The procedure involves the insertion of a flexible tube into your rectum and then passing it through your anus and into your large intestine. During this time, you will be sedated and monitored closely by your medical team. The scope is inserted up to the cecum, which is the last section of the large intestine. It takes about 30 minutes for the doctors to complete the exam, after which they can remove the scope and examine the results.
