<human>: I'm going to the doctor next week to have a colonoscopy performed. What should I expect during this procedure?
<bot>: During a colonoscopy, the doctor will insert a scope into your rectum and slowly move it through your entire colon. The scope is equipped with a light and camera that allows the doctor to view the inside of your colon. The doctor will also take biopsies from any suspicious areas they see on the video monitor. You may feel some mild discomfort or cramping while the scope is inserted and removed. Once the procedure is complete, you can expect to be given instructions for follow-up care and advice about diet and lifestyle changes if needed.
