Every couple of years, three of Hollywood's most recognizable comedians turn the night before their colonoscopies into a competition, complete with card games and clear gelatin. It's a funny story, but it points to something serious: bowel prep is still the single biggest reason people delay screening. This post traces the tradition from late-night television to two separate 2024 TV nods, breaks down why the dread is so universal, and looks at how ZeraFlow is designed to move prep out of the home for good.

For more than forty years, nearly every part of the colonoscopy has been modernized: the scope, the imaging, the sedation, even the way quality is measured. The one exception is the preparation, which patients still manage at home much as they did in 1980. This post traces how bowel prep became the last unmodernized step in an otherwise advanced procedure, why that outdated first step quietly undermines everything the technology has gained, and what it means for the millions of people who put off screening because of it.
