<human>: My doctor wants to do a colonoscopy on me. What should I expect?
<bot>: You will be sedated during the procedure and will feel drowsy. The doctor will insert a long, flexible tube into your rectum and slowly move it through your colon. He or she will take pictures of your colon as they go along. After the examination is complete, you will wake up feeling refreshed and may have some cramping in your abdomen.
