Can you really piss blood?
Plenty of reasons. Twice i woke up with my pijama pants full of blood, like, full. No scar, no wound, nothing, just blood. I never knew where it came from (as all places from where it could have come were with blood) but I assume it was urinated. It was a side effect of an antidepressant I was taking that start happening two years after beginning the treatment. I had to change the antidepressant and it never happened again
Yeah I'm pretty sure that's a key sign of kidney failure. It can happen rarely in cases of some crazy workouts, but if this dude is saying all the time then it's probably something worse.
If anyone's curious about why:
Muscles break down during workouts. They release myoglobin, which is a large protein. The kidneys can usually filter it in small quantities.
If you go too hard and give yourself rhabdomyolysis, your body releases a large quantity of myoglobin and it overloads the kidneys. Large proteins begin passing through the nephrons en masse and damaging them because they're too big.
Now your kidneys are unable to filter properly because the nephrons cannot contract to prevent excess fluids or particles from going into your urine.
Just in case this isn't enough warning, note that this can permanently reduce your kidney function and harm your body in other ways as well.
I know it's very unlikely for anyone here to do this, but if this happens you aren't just having a "crazy workout" you are giving yourself an injury and possibly permanently affecting your future health. So please don't exercise until you piss blood.
Also could be a UTI or STI(s). Or he eats beets all the time and isn't particularly bright. Could be anything, spin the wheel of medical disasters!
Friend of mine had strep throat as a kid and it somehow ended up infecting his kidneys causing him to piss blood, he's fine now.
but i don’t wanna have kidney failure :(
Just have someone remove your kidneys then!
Yeah, bladder cancer.
Piss is blood, in a sense. It's the bits of your blood that get sieved out and rejected by your kidneys.
Normally those are the only bits supposed to be getting out. But if the filter is busted (kidney trouble) or if the walls of the storage tank it sits in after filtering become damaged (bladder trouble), you can end up pissing actual, unfiltered blood.
Alternatively, you ate something recently with a strong red pigment that can survive digestion, enter the bloodstream, get strained out by the kidneys, and collect in your piss in high enough concentration to turn it red. Beets are a pretty famous culprit.
Not only bladder cancer but a whole bunch of things. I used to run home from work and I would always pee right beforehand so I wouldn't risk having to find some sort of place to pee, but then I started peeing blood every couple of weeks when my mileage went up to around the 10 mile mark. Apparently hematuria can happen from basically having a totally empty bladder chafe itself raw if you run long enough lol. I quit peeing before leaving work after my doctor recommended giving that a shot and it cleared up
yes though normally pee is brown/red from myoglobin accumulation (muscle breakdown) which is a sign of many things, some of them normally fine but many are extremely life threatening, and can lead to kidney failure. if your pee is ever brown or red you should most likely see a healthcare professional and have them do a urinalysis.
Yep. Kidney stones can make anything coming out of your urethra bloody. And holy hell does pissing blood that way hurt.
Yes, even for some minor things. I once got a UTI and didn't get it checked out for a week (I was mega dumb back then). What pushed me eventually to get a doctor to see me was when I started pissing blood. Not loads, but even a single drop was enough to spook me. Got some antibiotics and all was back to normal in a couple days.
