For many people, preparing for a colonoscopy is sometimes more daunting than the procedure itself.
You typically stop eating solid food for at least a day, and then drink what seems like gallons of liquid to clean out your bowel. You need to stay close to a bathroom, because you will be going and going and going.
Dread of the prep might be one reason why, according to government estimates, about 4 out of 10 Americans ages 50-75 don't meet recommendations for colorectal cancer screening. One common screening option is a colonoscopy every 10 years for those at average risk for colorectal cancer.
