While people often dread the prep involved for a colonoscopy, the screening saves lives. Read more to learn how to best prepare for this procedure, how much time it will take and other important information you should know about colonoscopies.

             Key Takeaways

• A colonoscopy is considered the gold standard for screening of colon polyps and colorectal cancer. It is a direct visualization of the entire colon and even allows the removal of any polyps that may be found.
• Colonoscopies are performed in an outpatient setting at hospitals or ambulatory surgery centers. During a colonoscopy, patients are put under sedation, and a flexible tube with a camera at the tip is inserted through the anus and into the rectum and colon.
• The procedure itself is painless, but the prep is often considered challenging. The goal is to empty your bowels so your gastroenterologist can properly examine the inside of your colon. If there's still stool in your colon, your doctor may not be able to see polyps or other problems and you may need to have the procedure again.
• Follow your medical provider's advice on bowel preparation for your colonoscopy, including adjusting your diet, drinking only clear fluids the day before the procedure and taking prescribed bowel cleansing liquids and/or pills.
