<human>: I'm going to the doctor next week to have a colonoscopy performed. What should I expect during this procedure?
<bot>: You can expect to be sedated for the procedure and will likely be monitored throughout it by your doctor or nurse. During the procedure, the doctor will insert a scope into your rectum to examine the inside of your colon. The doctor may also take biopsies (tissue samples) from any suspicious areas they see. Afterward, you'll probably need to stay in recovery for a while before being allowed to go home.
