Colonoscopy Q & A

What is a colonoscopy?

A colonoscopy is a procedure that allows Dr. Dicker to see the tissues inside your rectum and colon — large intestine — using a specialized instrument called a colonoscope.

The colonoscope is a tube that has a miniature camera and a light on one end. It’s slim and flexible enough to pass through your rectum and into your colon, where it sends back images of the colorectal tissues to a monitor.

Dr. Dicker can see clearly if there are any abnormalities in the tissues without having to make any surgical incisions.

When might I need a colonoscopy?

You might need a colonoscopy to identify inflammation or ulcers in your colon or to help Dr. Dicker diagnose the causes of symptoms like:

  • Lower abdominal pain
  • Rectal bleeding
  • Irregular bowel movements
  • Chronic diarrhea

Dr. Dicker also uses a colonoscopy to treat conditions that cause bleeding in the lower gastrointestinal tract and to screen for colorectal cancer.

How does colonoscopy help me avoid colorectal cancer?

Using the colonoscope, Dr. Dicker can see if any polyps are growing in your colon or rectum. These polyps are growths that, while not cancerous, can become malignant and spread cancer to other parts of your body if they aren’t removed. If Dr. Dicker spots any polyps, he passes surgical instruments down the colonoscope to remove them.

A colorectal cancer screening can save your life, so if you’re over 50, or you’re younger and have any risk factors for colorectal cancer, visit Dr. Dicker even if you feel well and don’t have any symptoms.

What happens on the day of my colonoscopy?

Before you arrive for your colonoscopy, you need to make sure your bowels are clear. Dr. Dicker gives you laxatives to take the day before your colonoscopy, and you should fast to ensure your colon and rectum are empty.

At the clinic, you’ll be given a sedative to help you relax and ensure you’re as comfortable as possible through the procedure. When you’re nicely relaxed, Dr. Dicker will put the colonoscope into your rectum and carefully pass it into the colon. This shouldn’t be painful, but you could be aware of a pressure in your bowels and experience some bloating or cramping.

Your colonoscopy will take 15 minutes to an hour, depending on the reason why you’re having the procedure. Afterward, you rest in the recovery area so the sedative can wear off, and then you can talk to Dr. Dicker about the results of your colonoscopy.
