Is colonoscopy painful?

Compared with gastroscope, enteroscopy is less painful. Usually you take medicine the day before and drink a big bottle in water the next morning. Be sure to clean up your stool. Otherwise, there is feces in the large intestine, so you can't see clearly when you check. If you want to feel comfortable, there is capsule endoscopy. Just swallow a capsule mirror. The capsule mirror is illuminated by a light bulb and photographed every few seconds. Doctors can also see the patient without any pain directly from the TV screen. But this is a self-funded project, and it costs at least 5,000 yuan.

When doing colonoscopy, due to the need of examination, a small amount of gas will be injected, which will cause abdominal distension. At this time, the anus will relax and the gas will be discharged.

In addition, due to the curvature of the intestinal cavity, the mirror will touch the intestinal wall when rotating, or go deep into the mirror, and then feel short-term abdominal pain.
