How To Prepare For A Colonoscopy

Colonoscopies performed by your gastroenterologists at Summit Digestive and Liver Disease Specialists in Oakbrook Terrace and Chicago, IL, offer important information about the health of your large intestine (colon) and rectum. Before you report for your colonoscopy, you'll need to do a few things to clear your colon.

Why preparation is so crucial

A colonoscopy gives your gastroenterologist a close-up view of the lining of your large intestine and rectum via a tiny camera passed through your anus. If feces remain in your colon, your doctor won't have a clear view of the lining and may not be able to see if you have a polyp, bleeding, or another health problem.

What's involved in colonoscopy preparation

The preparation process starts the day before your appointment when you'll begin making a few changes to your diet. You'll need to follow a liquid diet that includes clear liquids like apple juice, clear broth, coffee, tea, ice pops, gelatin, and sports drinks. Stay away from liquids that are red or purple. When you visit the Oakbrook Terrace or Chicago office to discuss your upcoming colonoscopy, the staff will share information with you about acceptable liquids.

You'll also need to take laxatives to clear out your colon. The process involves drinking laxatives or taking pills that make you poop. In fact, you can expect to make many trips to the bathroom during this part of the preparation process.

If you're using liquid laxatives, you'll probably need to drink some of the liquid laxatives the afternoon or evening before your colonoscopy and the rest the morning of the procedure. Be sure to follow your gastroenterologist's preparation instructions exactly.

You must avoid eating or drinking anything, even clear liquids, two to three hours before your colonoscopy. In most cases, you'll be able to take your usual medications that morning, but it's best to check with your doctor before taking any over-the-counter or prescription medications.
