eli5: Why does the serious urge to pee not correlate with the amount that comes out

1.20K views

So sometimes when the urge to pee is really bad it’s bordering on painful, like after a long sleep or car drive, not that much comes out. But then other times when I’m just chilling at home and go for a pee with no urgency I pee like Seabiscuit. What gives? What causes you to need to pee so badly it hurts cuz it doesn’t seem like it’s a volume thing?

Speak for yourself, when my bladder becomes serious I’m peeing for a literal minute straight. No joke.

And then I have to pee just as much in the next 30 mins.

Those are the times when I drink a lot of water. Sometimes I can even wait there a minute and pee again just a little bit.
