Generally, people aren't aware of the symptoms of gastrointestinal bleeding. I'd assume without a pretty good education outreach, it'd be unlikely to be caught except in the really bad cases. And while you're right, that GI bleeding on it's own might not be a huge issue, I suspect a gastroenterologist would want to do a colonoscopy if it does happen, something that patients probably wont to avoid if they can.
