Colonoscopy Q & A

What is a colonoscopy?

A colonoscopy is an evaluation Dr. Kodali uses to diagnose and/or treat abnormalities in your large intestine (colon) and rectum. To complete the exam, he inserts a long, flexible tube into your rectum. A tiny camera attached to the tube allows him to view the inside of your colon and detect or rule out problems.

Why would I need a colonoscopy?

Dr. Kodali uses a colonoscopy to:

  • Screen for colon cancer
  • Investigate symptoms of intestinal problems
  • Look for colon polyps
  • Detect or rule out gastrointestinal disorders


Symptoms of a problem that could require a colonoscopy include rectal bleeding, abdominal pain, ongoing diarrhea or constipation, or other unusual symptoms.

If you’re at risk of colon cancer or other colon diseases, it’s suggested that you have a colonoscopy every five years starting at 45 or 50. If your risk of colon diseases is low, a colonoscopy is recommended every 10 years, beginning at the same age.

How should I prepare for a colonoscopy?

Follow Dr. Kodali’s instructions before undergoing a colonoscopy at Park Gastroenterology. You must empty your colon by following a special diet the day before the procedure and using a bowel prep kit. Dr. Kodali might ask you to adjust your medications on the day before and the day of your colonoscopy.

What happens during the procedure?

You’ll change into a hospital gown before your colonoscopy. Dr. Kodali and his team will give you a sedative to help you relax and feel comfortable.

While you lie down on your side on an exam table, he gently inserts a thin, lighted tube (colonoscope) into your rectum. He pumps air into your colon to get a better view of its lining, moving the tube through the entire colon. You might feel some cramping or the urge to expel gas.

During the procedure, Dr. Kodali can take tissue samples (biopsies) and remove growths, called polyps. Most colonoscopies take 30-60 minutes.

What should I expect after my colonoscopy?

After a colonoscopy, you can go home, but you must have someone drive you there as it takes up to a day for your sedative to fully wear off. Take the rest of the day off from work and follow a special diet if Dr. Kodali asks you to.

You might feel a little bit bloated or have gas for several hours after a colonoscopy. You could also notice a small amount of blood in your first bowel movement, especially if you had polyps or other growths removed.

Dr. Kodali discusses the results of your colonoscopy and lets you know if further diagnostic testing or treatment is needed.
