ELI5: What would happen if you purposefully held in going to the bathroom?

What sort of damage would you cause or would you eventually just involuntarily go?

You would probably involuntarily go.

Before that - the immediate problem people tend to get when they delay using the restroom is bladder infections. But that's if you just routinely put it off for too long.

If you could hold it against all of nature's urges... Eventually you would either rupture something from too much pressure, or the pressure would start to back up the system, causing your digestive track and kidneys not to function properly.

Anyway, it's bad. Just go!
