Colonoscopy may be the most-hated medical screening.
The prep is miserable. You have to fast the day before. Then you have to take a laxative. This means hours of stomach cramps…and multiple trips to the bathroom.
And the procedure itself is no picnic, either.
It requires general anesthesia and a day of downtime. There is risk of bowel perforation. This is rare, but it can be life-threatening.
