Colonoscopy Q&A

When should I have a colonoscopy?

A colonoscopy is one of the most effective diagnostic tools for checking for early warning signs of cancer in your lower intestinal tract. In general, you need to have colon cancer screening at age 45. There are many other indications for a colonoscopy, including but not limited to: blood in your stool, changes in your bowel habits, chronic diarrhea, history of inflammatory bowel disease, or a history of colon polyps. 

What happens during a colonoscopy?

Dr. Harrington is a skilled gastroenterologist so you can feel confident that you’re in capable hands. Dr. Harrington ensures a colonoscopy is the right procedure that fits your unique needs and counsels you about what to expect during your procedure.

On the day of your colonoscopy, it’s important to have a driver to and from your procedure, as you should receive a sedative that will help you relax. This sedative generally wears off in 30 minutes, but you may feel tired for the remainder of the day. Normally, patients can return to their normal activities the next day.

During the procedure, you will lie on your side with your knees bent towards your chest. A thin tube- the colonoscope- is entered into your anus and advanced to where your small intestine meets your large intestine. In general, most polyps can be removed during the procedure, and any abnormal areas can be biopsied.

How do I prepare for a colonoscopy?

To ensure Dr. Harrington can clearly see the lining of your intestines, it’s important to undergo a bowel preparation the day before your colonoscopy. Any lingering residue may block views of your colon and rectum. Dr. Harrington may recommend:

  • Consuming only clear fluids for at least 24 hours beforehand
  • Stopping certain medications and supplements
  • Consuming a bowel preparation to help cleanse your colon

It’s also essential to avoid any beverages, broths, frozen pops, or other types of clear liquids that have red food coloring. The red color is sometimes mistaken for blood during a colonoscopy. You will receive detailed instructions from Dr. Harrington’s office prior to your procedure.
