How does water digest?

When I was doing Brazilian Jiu Jitsu, I could not eat 2 hours before class it had to be more like 3 hours. However if I drunk water in class, it didn't effect my performance like food does. DOesn't water have to go through the entire digestive track like food? How come after say a few hours you have to pee after drinking a lot of booze or tea?

I thought only protein was digested there due to the acid. Unless pepsin digests sugars?

No. Stomach and small intestine.

I never tried sugar water for exercise. That might be fun. Glucose is mainly digested in the mouth correct?

I assume that water is stored in muscle tissue, fat tissue and blood vessels? I have never been a big water drinker since I assumed it never would help with digestion. I drink at least 2 glasses a day.

Part of the function of the colon is to extract water from feces. If you are well hydrated, it won't extract as much, making it easier to, well you know... poo.

So it never reaches the colon. Also Not sure how drinking water would make it easier to poo.

I don't know the underlying science but, regardless of what time of day it is, when I drink water kefir or coffee it's more like an hour or two later that I have to pee. I think water is absorbed along the way otherwise you'd be pooping liquid.

About 80% of the water passes into the bloodstream at the small intestine, and from there to the kidneys for removal.

It doesn't go through the entire digestive tract. Some in the stomach, most in the the small intestine. Don't know the distribution though.

There's not a lot of energy required to 'digest' water. Have you had the same difficulty with taking glucose in liquid form within 2 hours of exercise? And if there's a lot of water in the system, the body will release more through the kidneys - it doesn't have to be the same water, there's quite a lot hanging around.
