Colonoscopy FAQ: What to Expect Before, During & After

March is Colorectal Cancer Awareness Month, bringing attention to the second leading cause of cancer death in the United States, behind only lung cancer.

Colorectal cancer is also one of the most preventable forms of cancer and a colonoscopy is the primary method of detection. It allows for not only early detection but also treatment as your doctor can remove polyps during the procedure that can otherwise turn into cancer.

The Endoscopy team at SVMC receives a lot of similar questions about the when, the how and ‘the what’ of colonoscopies As screenings can be up to 10 years apart, even patients familiar with the procedure can be understandably confused about how to prep and what to expect. Below are the most frequently asked questions in regards to prepping for your colonoscopy and what to expect during and immediately after the procedure.

Q. My colonoscopy is scheduled. How do I prepare?

A. There are several different preps that can be used prior to a colonoscopy that involve taking a laxative and following a clear liquid diet for a period of time. Your provider/nurse navigator will select a specific one based on your individual needs. Please follow the prep that you have been instructed to use prior to your colonoscopy. REMEMBER: Not following the directions can lead to your procedure being cancelled. If you have questions, I encourage you to call your provider’s office to get clarification and guidance. Also instructions can be found on the SVMC webpage as well. 

Q. Are there any foods I need to avoid beforehand?

A. You will receive detailed instructions from the GI Navigator of foods to avoid. Usually these include high fibrous foods. 

Q. Will I be put under?

A. Most colonoscopies do not require general anesthesia but you will be given a sedative and pain medication to ease discomfort. In some cases, anesthesia may be required.

Q. If I’m awake, what do I do during the procedure?

A. You’ll be wearing a gown and begin by lying on your side on a stretcher. Usually, your knees will be up, like you’re sitting on a chair. In total the procedure will take 20 minutes to an hour.

Q. How are polyps removed during the procedure?

A. Polyps are removed painlessly using special tools that can be passed through the camera on the colonoscope. 

Q. What should I expect afterwards?

A. It takes about a half hour OR more to recover from the sedative. You may feel bloated or tired temporarily. There are no dietary restrictions following your procedure.

Q. How long will it take to get my results?

A. Typically results are received within 7-10 days.
