Question about Dehydration and Urine?

Question

Why does your urine become so dark when you're dehydrated?

Answer 1

Your urine becomes extremely concentrated when you are dehydrated. A large percentage of urine is water, which is why urine is light colored. Therefore, when you're dehydrated, there is less water in your urine and more toxins, etc.

Answer 2

The rubbish your system needs to dispose of travels in two directions. The bulk and easier waste goes through the backside.

The rubbish that is passed through urine needs water not just to carry it but also to dilute it.

The more dehydrated you become the darker the urine becomes. This is a sign of danger.

You are putting both your liver and kidneys into difficulty which could quite quickly lead to organ damage and failure.

Simple dehydration causing urine to colour can usually be remedied by drinking water. The more dehydrated you are the less drinking water is effective. you need electrolites and the best for that is sports drinks.

Allowing yourself to become dehydrated can be dangerous and the less water, the darker the urine the more it will burn to pee.

Answer 3

When a person is dehydrated the hypothalamus in the brain reduces the release of the hormone ADH. This creates a urine with very little water and more dissolved solids. When the urine passes through the nephron, a lot of the water is reabsorped because it is desperately needed for your body. Therefore, the leftovers are darker because the urine is more concentrated with solids of dark colors, rather than clearer because of the dilution by lots of water.

Answer 4

I don't know about color but in Human Phys I learned that your urine isn't supposed to have a strong smell, that smell is a hormone that is released when you are dehydrated so that your body looses less water in urination. That may account for the color too but I can't say for sure.

Answer 5

Because you're body hangs on to water, so you're concentrating your waste products, which can clog up your kidneys. Its always best to drink a lot of water or caffiene free/sugar free drinks, like Crystal Light or diet soda to keep your kidneys flushed out and keep the waste products out of your body. Below is an interesting article I found when I was going to nursing school and I had to do a paper on dehydration.

Answer 6

Sometimes when you're dehydrated the bladder walls rub together and cause bleeding. The blood in the urine causes the darker color. Drink lots of water to avoid this problem or painful kidney stones.

Answer 7

The kidneys filter out certain wastes from the blood along with water. They also remove water from the body. The more water that is available, the more the kidneys will flush into the bladder. If you are dehydrated you are seeing the waste products getting concentrated in the urine. This is not good for your kidneys or bladder. Drink more fluids, especially water.

Answer 8

Because it is dense minerals and waste products from your body. Your body is trying to use a little liquid from your cells as it can to pass the stuff off.
I quick way to see if you're dehydrated: Raise your hand to your face. If the veins in your hand doesn't flatten within 30 seconds, you need to drink more water.
