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

1.34K 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?

If your a guy, you need to get your prostate checked. Ask doc for a PSA blood test, unless you really want a digital exam.

For real, prostate cancer any hypertrophy are real.

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.

One thing that hasn’t been mentioned is the risk of prostate cancer. If you’re a guy and this is happening, you should get checked.

Honestly you probably need to do a few kegals and learn to hold it a bit more. I’ve found that your body can get used to going at the same times every day so if you keep going often throughout the day even though there isn’t much there, it’s likely your body simply accepts that is how often you should go. The other option is prostate cancer…

Your bladder wall contains nerve endings which are sensitive to a number of things, and a few things can go wrong with them as well. Assuming it’s not neurological (like overactive bladder, very unlikely), it’s probably based on what you drink. Some things, when filtered by the kidney and passing into the bladder, are bladder wall irritants. Your brain can’t differentiate between the signals from the bladder stating “I’m full to bursting” from “I’m really irritated by the (ph/caffeine/alcohol/specific gravity/bladder stones/bacteria/whatever)”. Both are perceived as the need to pee.

Try drinking more water. You don’t need to drink that much, but make a conscious effort to drink more than you do and that should help. Water is very easy on the bladder and a good diluent of irritating things.

You may quite possibly have a UTI (Urinary Tract Infection). If it’s not possible to go see a doctor for lab tests you may like to try some AZO. Which is an over the counter relief of sorts. You can find it at most drug stores/pharmacies.

Maybe it’s the amount of salts/minerals/whatever else is in your pee. Like you need to pee and only a little bit of dark pee comes out or a lot of light/clear pee comes out.

I had the same problem as most every male will have at some point. As you age the prostate gland continues to grow which places pressure on the urethra as well as the bladder. In my case the urologist removed a portion of the prostate and now I pee like an 18 yo. No cancer luckily and everything is fully functional. A urologist can do an ultrasound of the bladder and get a pretty good idea what is going on, this is not something to get diagnosed on reddit, go see an MD.

I find that when I need to pee but nothing is really there, it’s usually the gas built up in my intestines pushing against my bladder. If you get stomach pains or lower back pain accompanying it that may be the cause. Obviously go to a doctor if something feels off.

Eating dried cranberries and pepitas (pumpkin seeds) can also help reduce the need to pee as frequently.
