why do i pee when i throw up?

Well since these other two people didnt really give any thoughts on this I figured I might try. I think its just because when you puke and its violent, that force on you stomach, throat, etc. makes you lose control of things like your bladder. I would compare it to when people do yoga and it makes them pass gas or when you laugh so hard you almost pee yourself. It's like all your force is put into doing one thing so you cant so easily control other things! Im not a doctor nor is this a professional opinion but this is my opinion.

Peeing While Vomiting

Looks like your pee pucker string is hooked up to your puke engagement responder. This is called dual lockup syndrome, which is caused by a bilateral nerve connector which allows for electrical responses for one thing to short out to another thing, and visa versa. It's kinda like when you want to pee when your turn on a faucet, or you want to pee when you're around an outdoor campfire. As odd as it sounds, it's common, so don't worry about it, just try to quit puking for a while and the shorting- out nerve interconnection will develope a natural insulation to eliminate your problem.

Urinating after you have been excessively vomiting is unfortunately pretty common. It can even happen if you are trying to blow up a lot of balloons. It also can happen after you have been laughing a lot. Do not know if it is just one part of your body relaxing while the another part is involved. Best way to control the problem is to drink more moderately. Excessive vomiting can seriously damage your throat and cause stomach ulcers.

Maybe you just have a weak bladder, and the force and jolting of throwing up just forces it out. I had a friend would would pee herself if she laughed, sneezed or coughed too hard :]

forces the pee from out of the bladder normal

Go see a doctor. Hopefully nothing is wrong but just to be on the safe side.

weak bladder...

When you heave to push out your sick, sometimes if you have a full bladder you can push its threshold letting off your reflex in your bladder to willingly but unkowningly let yourself urinate.

dont worry about it

I know how you feel. I asked my doctor once and she told me its just simply due to how forcefully you vomit. I dont think there is anything wrong with you.

probably from being so forceful when youre throwing up, it just happens.
