A colonoscopy is a medical procedure that involves using a long, flexible tube called a colonoscope to examine the inner lining of the large intestine and rectum. As daunting and uncomfortable as thinking about getting a colonoscopy may be, colonoscopies are a valuable tool for evaluating and monitoring gastrointestinal conditions. They’re also the most effective way to prevent or detect colorectal cancer early when it’s easiest to cure. Preparing for a colonoscopy will require a little extra work on your part because your colon must be completely clear so your doctor can see any abnormal areas on the bowel wall. Performing the procedure on a clean colon improves the likelihood that your doctor can identify existing problems during the examination. Read on to see what you can eat before a colonoscopy.
Your bowel should be as empty as possible for the examination. For this reason, your doctor may recommend a low-fiber diet beginning several days before a colonoscopy to help prepare your colon. Foods like grains, fruits, and vegetables all include fiber, which the body does not digest. Fiber may cover areas your doctor needs to see if it stays in the digestive tract, leading to an incomplete examination or missed precancerous polyps.
Low-fiber foods ease bowel preparation by lessening the amount of undigested food that must pass through your digestive tract. Less debris and undigested food moving through your large intestine will ensure your doctor can thoroughly examine your bowel. Low-fiber food options to enjoy two or three days before your procedure include:
It is necessary to avoid foods during this time that can interfere with the procedure or make it more difficult to clean the colon. Foods to avoid two or three days before a colonoscopy include:
A clear liquid diet is recommended one day before a colonoscopy. Clear liquids are transparent fluids you can see through when held up to the light. They are easy to digest and leave minimal residue in the colon. They also help to prevent dehydration and electrolyte imbalances in the days before and after your procedure. Liquid options to enjoy one day before a colonoscopy include:
The following liquids can interfere with the test and should be avoided:
Your doctor’s office will provide you with detailed information on how to prepare for your colonoscopy.

Following your doctor’s diet and preparation instructions is critical for a successful colonoscopy. It can ensure that your colon is clean and ready for the procedure, improving test accuracy and lowering the chance of complications.
