The time for a colonoscopy usually ranges from 15 to 30 minutes.
If the patient cooperates well and no intestinal disease is found, the examination usually takes about 15 minutes. If the patient is highly nervous or irritable and cannot cooperate, the examination time will be prolonged accordingly.
If intestinal polyps are found during colonoscopy, they need to be removed, and the longer the number of polyps, the longer the examination time will be, which usually takes about 30 minutes.
If a painless colonoscopy is performed, it usually takes about 30 minutes due to general anesthesia.
It is important to cooperate with your doctor during the colonoscopy.
