A colonoscopy is a procedure where the colon, large intestine, and rectum are checked for polyps or tumours. It begins with an injection of sedative into the blood to minimise discomfort during the colonoscopy.
The colonoscope enters through the anus. The colonoscope is about one inch wide and has a light on it to allow the doctor to see inside. A colonoscope has a long tube fitted with lenses, a light, and a tiny video camera on the end of it.
The colonoscope is able to detect both benign tumours and malignant ones. The colonoscopy is usually performed when there are no symptoms present but in some cases, you may have symptoms that suggest you might have cancer of the colon or rectum. If polyps are found, they will be removed during the colonoscopy.
The colonoscopy is a safe procedure and any complications are rare. Most people feel fine after the colonoscopy. Some people may experience a bit of discomfort when they go to the toilet afterwards. This is because the colonoscope can push some faeces out of the colon when it is removed.
If you are having a colonoscopy, you will need to stop eating and drinking for at least six hours before the colonoscopy. You will also need to take a laxative to clean out your colon. This will help the doctor see the colon more clearly.
The colonoscopy is a painless procedure that only takes a few minutes to perform. You will be able to go home after the colonoscopy. Most people feel fine after a colonoscopy but if you have any problems, please contact your doctor.
If you are having a colonoscopy, make sure to tell your doctor if you are pregnant or have any allergies. Also, let your doctor know if you are taking any medication.
If you have any other questions about colonoscopies, please ask your doctor.
