Ryan Reynolds announced this week that doctors discovered a polyp during a colonoscopy he had after losing a bet.

After Reynolds’ colonoscopy, his doctor, Jonathan LaPook, shared that he found a polyp, a discovery that was “potentially lifesaving.” 

McElhenney also had three polyps that were discovered and removed. And had no symptoms. There is nothing to worry.

A colonoscopy (koe-lun-OS-kuh-pee) is an exam used to look for changes — such as swollen, irritated tissues, polyps or cancer  in the large intestine (colon) and rectum.
