What is Colonoscopy?

In simple terms, Colonoscopy is an exam conducted to have a clear view of the of the large intestine (colon) and rectum. A specialist doctor can ask you to undergo Colonoscopy to check for inflamed or irritated tissues, polyps and cancer in the colon. The doctor can even take biopsies (tissue samples) during a Colonoscopy to be examined later.

Why is Colonoscopy done?

A Colonoscopy can be recommended to you by a specialist doctor under the following circumstances:

Colon Cancer Screening: A Colonoscopy is generally recommended every ten years for patients above 45 years who have minimal to zero risk for Colon Cancer. In case you have risk factors, a Colonoscopy is recommended sooner to check for Colon Cancer.
To Look For Intestinal Problems: A Colonoscopy can be recommended if you have symptoms such as chronic diarrhea or constipation, constant pain in the abdominal region or rectal bleeding etc. The underlying causes for all such symptoms can be determined by Colonoscopy.
For Treatment Purpose: A Colonoscopy specialist can recommend you the examination for certain treatments such as taking out an object or putting a stent in the colon.
To Check For Polyps: If you had polyps previously or have a higher risk of developing them in the future, a Colonoscopy is advised for examination and removal of the same so as to decrease the risk of Colon Cancer later on.

How do you prepare for Colonoscopy?

Your colon needs to be completely clean before the procedure of Colonoscopy. Therefore, you will be asked to follow certain steps by your specialist doctor so that the test can be conducted smoothly.

Consume a laxative: You will be mostly prescribed a laxative which can either be in pill or liquid form. You will be required to take the laxative the night before Colonoscopy as well in the morning when the procedure needs to be done.
Modification in your medicines: In case you are diabetic or a heart patient, it is important to inform your specialist doctor about all your medications and supplements. He will either stop certain medications completely or modify the dosages of some.
Follow the diet instructions: Your specialist doctor will advise you regarding the diet you need to take a day before Colonoscopy. Mostly, solid food is prohibited a day before the test and only plain fluids are allowed. Red liquids are not allowed as they can be mistaken for blood during the procedure.

What is the Colonoscopy procedure?

The patient is given a sedative along with pain-relieving medication to avoid any discomfort during the procedure.
The position for Colonoscopy involves lying on one side and drawing your knees towards the chest.
A colonoscope consisting of a camera, light and tube is then inserted into the rectum. The tube is utilized to pump water or air into the colon so that the doctor can get a clear picture of the colon lining.
Stomach cramping is common while the colonoscope is being moved to get a better view.
Biopsies can be taken by the doctor during Colonoscopy. Polyps or any abnormal tissue can also be removed by inserting the requisite instruments through the tube.

What to expect after Colonoscopy?

The effect of sedative administered before Colonoscopy starts to wade away after almost an hour of the test.
Arrange for someone to take you back home as you will not be able to drive.
Bloating is common for some hours after the procedure and going for a slow walk can help in relieving the gas easily.
The first stools passed after Colonoscopy can contain traces of blood and this is completely fine. However, if there is persistent bleeding, passing out of blood clots or extreme abdominal discomfort, inform your specialist doctor immediately.
Depending on the results of your test, the doctor will recommend re-testing or advise the future course of action.
