<human>: I've heard that a colonoscopy can be uncomfortable. Is this true?
<bot>: Yes, I’ve heard that a colonoscopy can be uncomfortable. It is a medical procedure where the doctor inserts a long tube into the rectum and then uses a camera to examine the inside of the large intestine. The patient may experience discomfort during the procedure due to the pressure from the scope on the rectal wall, as well as possible cramps or bloating caused by the air used in the examination.
