What happens during a colonoscopy?

Another way to do a Colonoscopy

The doctor can ask during the examination if the patient wants to lie down on the back or another side. An assistant can also press his hands on the patientu2019s stomach. The investigation takes about 15 to 30 minutes. If the doctor carries out procedures during the examination, the examination will take longer.

In about ten percent of people, it is not possible to examine the entire colon. It then fails to move the endoscope up to the small intestine. For example, because of sharp bends or narrowing in the intestine or because moving the endoscope is too painful. In that case, the doctor may propose to carry out another examination to examine the patientu2019s colon.

In many hospitals, the patient can choose a colonoscopy if the patient want a whip during the examination. The doctor will discuss this with the patient in advance. If this does not happen, the patient can ask for it himself. It is essential that the patient indicates the intention before the day of the investigation using a robe so that the patient can prepare for it.


A robe is also called sedation. That means that the patient get soothing, sleep-promoting medication. The effect of a robe differs per person. Some people fall asleep, while others are only a bit dazed. The robe makes the patient feel more relaxed, and the patient feel less pain and anxiety.

The patient can follow instructions from the doctor. The medications for the cream are administered via an infusion. If the patient get a whip, the nurse will inject an infusion needle into the patientu2019s hand or arm. Medicine is then injected through the infusion.

The patient gets a peg on his finger. This allows the nurse to monitor the patientu2019s heart rate and breathing during the examination. This is necessary because when using a whopper there is a small chance of complications due to the medication such as breathing problems and problems with the heart. This applies especially to people who are over 70 years old and suffer from heart disease, lung disease or other condition.

Please note that the patient is not allowed to participate in traffic on his own when the patient receive a robe. It is therefore essential that patient arrange transport or that someone comes with the patient. In young children, a colonoscopy is usually performed under anesthesia. In adults, this adjustment rarely happen.
