Does electronic colonoscopy hurt?

If electronic colonoscopy is done in a conscious state, there is a certain feeling of abdominal pain. If painless colonoscopy is done under general anesthesia, there is no pain. If there are colonic polyps or it is necessary to take materials for treatment, it is better to do painless colonoscopy, because the pain is obvious when removing some tissues, and some people cannot bear it. On the first day after colonoscopy, it is generally recommended to eat liquid food that is relatively small and easy to digest.
