Human body water percentage

What would happen if the water in the human body dropped to less than 60%-70% and is there any possible ways that this will happen?

Prolonged diarrhea can be deadly, especially in babies and children. An adult could probably have diarrhea for a few week, but could then die from it because you lose sooooo much water. It can also happen by injecting someone with intravenous salt water - which would dry out all their cells by the laws of osmosis. Also, if you are bleeding, you can lose huge amount of body fluid. There are also medical disorder which cause you to urinate too much, as Diabetes Insipidus (this is not the same of diabetes most people have, which is diabetes mellitus) and we are talking like urinating several liters per day.

Oh also, generally if you lose more than 50% of your blood fluid volume you would pretty much die for sure. It is also important to differentiate intravascular fluid from intracellular fluid to answer what would happen.

yes the human may die or become immensely week due to dehydration.this phenomenon takes place either in loose motions or diarrhea or even due to less consumption of water even causing jaundice.

Yes it is possible if the person does not drink anything which is very bad for them. They will become dehydrated and if they don't get fluids short after they will die.

you would likely to die of hydration. if you dont drink water, then you would probably drop waters in human body.
