Preparing for Colonoscopy

What is Colonoscopy?

This is a special test using a flexible tube to look at the internal lining of the colon and rectum, It also allows biopsies to be taken.

Your doctor may recommend a colonoscopy examination if you have symptoms suggesting possible problem in the colon or rectum. Some symptoms include bleeding, change in your bowel habits, unexplained abdominal symptoms. Colonoscopy is also used to monitor patients with inflammatory bowel disease, and for follow-up of patients with history of colon cancer or polyp.



The bowel must first be thoroughly cleaned before a colonoscopy. This is done either the day before or the same morning as your colonoscopy. You will be asked to drink medication that would make you have diarrhea to pass out all the stools inside.
