As you age, staying active and healthy becomes more and more important. Preventative care also gains importance, ensuring that your colonoscopydoctor finds and treats any potential health concerns early before they become more complex issues requiring more invasive treatments. Colonoscopy is a super-effective preventative tool, helping patients stay healthy for years to come. Should you have a colonoscopy? Learn more about this important procedure with your gastroenterologist, Dr. Melvin Bullock with locations in Roswell, Suwanee, and Atlanta, GA.

What is a colonoscopy?
A colonoscopy is a procedure performed by your gastroenterologist to investigate gastrointestinal symptoms or as a screening for colorectal cancer. The procedure itself uses a long, thin tube called a colonoscope inserted rectally to scan the lining of the colon and large intestine for abnormalities. These abnormalities, called polyps, may be cancerous or pre-cancerous and doctors will often take a biopsy to test for the presence of cancerous or pre-cancerous cells. The procedure normally takes anywhere from 30-60 minutes and occurs in your doctor’s office. Your doctor will administer sedation medication prior to beginning your procedure to help you feel relaxed.

Do I need a colonoscopy?
The American Cancer Society recommends that all women and men over the age of 50 should have a colonoscopy every 10 years. However, those with a high risk for colorectal cancer may need a colonoscopy more often. Those at a higher risk of colorectal cancer include individuals who have a family history of cancer, especially colorectal cancer or polyps, a personal history of colorectal cancer or polyps, or someone with an inflammatory bowel disease.

After your procedure, your doctor will probably ask you to stay in a recovery room for about a half hour to ensure that there are no adverse effects due to the procedure or medications used. Prior to your procedure, you will fast and take laxatives to cleanse the colon and ensure that it is clean and free from debris during your procedure.

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.

Have any questions about your upcoming colonoscopy? Dealing with gastrointestinal issues that aren’t going away? Then turn to your Roswell, GA GI doctor for the care you deserve.
