Prepare yourself for this upcoming GI procedure by finding out what it will entail.

A colonoscopy is a fairly common procedure that your Roswell gastroenterologist Dr. Melvin Bullock may recommend if you are colonoscopyexperiencing rectal bleeding or other suspicious GI symptoms. Any new procedure can feel a bit scary, especially if you don’t know what to expect. Find out what will happen during your colonoscopy so you can breathe a little easier.


In order for your procedure to be successful, your bowels must be empty. This will allow your Roswell GI specialist to be able to clearly see your colon. We will prescribe either a liquid or pills that will help to empty out your bowels. We will also give you special instructions that you will need to follow before your colonoscopy to make sure everything goes as smoothly as possible.

Your Procedure

Once you put on your hospital gown an IV will be started. Sedatives and pain relievers will be administered through the IV to help you feel relaxed and drowsy. Before your procedure, we will discuss what kind of anesthesia we will use, whether general or conscious sedation.

Once the medication has taken effect, you will lay down on your left side with your knees up to your chest. A colonoscope—a small, flexible tube—will be inserted into the rectum and slowly directed into the large intestines. Some air will be used to expand the colon so we can check the health of the colon walls.

If there are any suspicious growths we can also take a biopsy of this tissue during your colonoscopy. Colonoscopies are so beneficial because it often allows us the opportunity to diagnose and treat colorectal conditions without needing a major operation to do it.

Once we have checked the health of your colon we will slowly remove the colonoscope from your bowels. The procedure can take anywhere from 30 minutes to one hour.
