Colonoscopy Q & A

What is a colonoscopy?

A colonoscopy is a procedure that allows a doctor to look inside your large bowel, or colon, using a small camera called a colonoscope. The colon, which is about 5 feet long, is the last portion of your digestive tract and stores unabsorbed food waste until it eliminates it as stool.

As you age, there can be complications in the colon, such as inflamed tissue, abnormal growths, ulcers and colon cancer that Dr. Pullano can find with a colonoscopy. This quick and painless procedure can detect causes for symptoms that include:

  • Changes in bowel habits
  • Abdominal pain
  • Rectal bleeding
  • Weight loss


If you are experiencing any of these symptoms, reach out to Dr. Pullano. He can check you out to make sure you’re not at risk for colon cancer.

How do I prepare for a colonoscopy?

You’ll have some preparations before you have your colonoscopy. For Dr. Pullano to get the best possible look inside your colon, it must be empty. This helps to ensure the procedure is thorough and safe.

To empty the colon, Dr. Pullano will suggest a liquid diet for a day or two before treatment. This diet should consist of:

  • Fat-free bouillon or broth
  • Strained fruit juice
  • Water
  • Plain coffee
  • Plain tea
  • Diet soda
  • Gelatin


The night before your colonoscopy, Dr. Pullano will ask you to take a prescribed laxative to cleanse the bowel completely. In some cases, you may be asked to receive an enema or perform one on yourself.

Do I need to get a colonoscopy?

Yes. One of the leading causes of cancer deaths in the United States is colon cancer for both men and women. In most cases, a polyp can take as long as 10-15 years to develop into colon cancer. With regular colonoscopy screenings, Dr. Pullano can detect early cancer and precancer signs and provide you with safe and effective treatment before cancer spreads into the body.
