Human: I'm a little nervous about my first colonoscopy. What can I expect? Assistant: 
You may feel some discomfort during the procedure, but it should be minimal and easily managed with medication. The doctor will insert a small tube into your rectum to help them get a better view of your colon. During the procedure, you may also be asked to drink a liquid called polyethylene glycol (PEG) which helps cleanse your colon and makes it easier for the doctor to see any polyps or other abnormalities. After the procedure, you will likely experience cramping and bloating as your body absorbs the PEG solution. These symptoms should subside within a few hours.
