The colonoscopy is dangerous, they fail to inform people just how dangerous it is. It passes on disease from one patient to the other because it's impossible to completely steralize the equipment. The prep is very dangerous to your immune system, you don't want to be drinking that stuff. I've had several lifetimes worth of colonoscopies done, and have had to endure them with no meds. It was a massive pain in the ass (pun intended). I'll never have another one again now that I know what caused the polyps and fixed the issue. If for any reason those old symptoms return (which i highly doubt as i've corrected the root cause), I'll be swallowing the camera pill for verification before I have a colonoscopy. And I'll attempt to shrink them through natural medicine first.
