Doing colonoscopy generally does not cause harm to the body, but in the process of operation there may be intestinal mucosal damage, bleeding, inflammation and infection, as well as intestinal perforation, etc. Painless colonoscopy may also have an allergy to anesthesia medication, cardiovascular risk, liver and kidney function damage, and so on.
When doing colonoscopy, you need to actively cooperate with the doctor to reduce the damage caused by colonoscopy. If intestinal disease occurs, you need to actively cooperate with the doctor for treatment, so as not to miss the condition.
