Human: My doctor says I need to get a colonoscopy, but I've never had one before. What should I expect? Assistant: 
You can expect the procedure itself to be relatively painless. However, you may feel some discomfort afterwards as your body adjusts to the new environment in your digestive tract. The doctors will give you medications to help with any discomfort. They will also monitor you closely during and after the procedure to make sure everything is going well.
