YOu seem to misunderstand basic physical processes. YOu can't
just keep losing fluids without taking in more to replenish
what you lost. This is as basic as 2+2=4. It goes without saying
that no matter how you lose water i.e. via kidneys, sweating
or tears it has to be replenished. And if you excrete salt with
the fluids you are obviously excreting salt.
My feeling is that you want to say something else (and I can
guess what) but don't know how to say it :-)..
