Our kidneys filter excess water and waste out of our blood and that urine needs somewhere to go our bladder normally it will hold one to two cups comfortably but if you make a habit out of holding your pee for long periods of time you can actually stretch your bladder to easily hold even more one study found that nurses who often held it in all day due to job constraints had nearly double the normal bladder capacity and turns out they were totally fine but that doesn't mean that you should hold it in if you can help it because your bladder might not be the only thing to stretch you may also stretch your external sphincter muscles those are important muscles connected to the outside of your bladder that are the gatekeepers of just golden liquid clench them and you hold in the gold relax them and you release it.

If you over stretch them you can actually lose control this is rare and it usually takes decades of holding it in too long to reach that point but once you do it can lead to some awkward and even dangerous situations for example with less overall control you risk leaking urine when your bladder is full and not emptying it all the way when you finally do go not only can this increase your need to urinate more often since your bladder fills up quicker it can also lead to a serious disorder called urinary retention where you end up with too much urine in your bladder for too long and since your bladder is basically a warm wet bag of body waste it's the perfect breeding ground for harmful bacteria that will cause all sorts of damage even worse if you're really unlucky and retained too much urine it may back up into your kidneys this can cause kidney failure and ultimately death the good news is you're more likely to just lose control of your muscles and pee way before your bladder hits this point why not reduce the risk altogether and just go to the bathroom .Luckily you'll be fine if you only hold it in for a short time every once in a while so go ahead hang in there just don't make a habit.
