You should be able to pass clear and liquid stool before the test. Any stool remaining in your intestine will hamper in the procedure, and the doctor will be unable to clearly see the lining of the intestine.


Doctors advise patients to follow a clear liquid diet for 1 to 3 days before the scheduled procedure—no consumption of red or purple coloured drinks or gelatin. Also, instructions are provided with regards to beginning and stopping the clear liquid diet.

Cleaning of bowels is suggested as follows -

The patient is supposed to take laxatives either in the form of pills or powders is prescribed that have to be swallowed or dissolved in plenty of water This water is consumed in large quantities in a specific period which is usually night time i.e., before the morning of the scheduled procedure. If necessary, enema is also prescribed.

The patient will be unable to drive a vehicle 24 hours after the colonoscopy procedure, so arrangements will have to be made accordingly.  


The colonoscopy procedure

Colonoscopy is a short-term procedure that lasts up to 20 minutes maximum. It is performed in a hospital or as an outpatient department. The patient will receive sedatives, anaesthesia, or pain medication through an IV for a pain-free experience. The nursing staff will monitor the vital signs of the patient. 


The procedure begins with the doctor inserting the colonoscopy through the anus, rectum, and colon. The scope will then inflate the large intestine with air enabling the doctor to get a good view. 


Also, the doctor will be able to view for better examination of the intestine. As required, the doctor will request the patient to move for better viewing. Through this procedure, the doctor can view the small intestine too.  


Polyps are removed if present for further testing. Most colon polyps are harmless, but it is essential to check them since they indicate colon cancer. Abnormal tissue is located, is also removed for biopsy purposes.
