Colonoscopy Q & A

What is a colonoscopy?

A colonoscopy is a procedure where a flexible tube with a light source is inserted into the rectum and advanced all the way through the entire colon to where the beginning of the colon meets the small bowel. You’re typically sedated for this painless procedure.

Air is used to expand the colon so that your physician gets excellent visualization of the lining of the colon. Conditions such as blood in the stool, diarrhea, a change in bowel habits, or abdominal pain of unclear cause may be indications for a colonoscopy.

If your doctor finds any abnormalities during the colonoscopy, any polyps may be removed and biopsies can be taken in areas that are abnormal. After the procedure, your doctor sits down with you to go over the results.

How do I prepare for my colonoscopy?

Prior to your colonoscopy, you must take a colon prep in order to clean your colon. The cleaner you get your colon, the better job your doctor can do regarding finding any abnormalities.

There are numerous preps for colonoscopy, and your doctor gives you the options. Please click on the link of the prep that your doctor chose for you so that you can understand how to take your prep.

You’ll be on a clear liquid diet at least one day prior to your procedure. A low-residue diet is also implemented two to three days prior to that. You should take nothing in by mouth within six hours of your colonoscopy.

Once again, it’s imperative that you work hard on getting your colon clean with the preps, so your doctor has the best look possible at your colon.

Does having a colonoscopy hurt?

Colonoscopy is a well-tolerated procedure. During the procedure air is used to open the colon so your doctor can see the lining of the colon. Every attempt is made to remove as much as gas as possible after your procedure, thereby minimizing any cramping or abdominal bloating.

You’re asleep during the procedure in order to keep you comfortable, and the medical staff monitors your blood pressure, heart rhythm, and breathing.

How will I feel after the colonoscopy?

You’ll sleep for approximately five to six minutes after your colonoscopy until the anesthesia wears off. At that time, you begin to wake up and your doctor talks to you and a family member regarding the findings at the time of colonoscopy.

You may have some mild abdominal distention from gas used during your procedure, but this goes away once you get up and move around. You’ll be able to eat as soon as you’re awake enough; however, it’s recommended that your first meal be somewhat small due to the anesthesia used for your colonoscopy.

You won’t be able to drive and need to have a driver to take you home afterwards. It’s normal to feel some abdominal bloating and possibly mild cramping after the procedure.
