I don't know if I agree with some of the posts on this subject. If you eat excessive sodium in your diet and drink water, your body will retain some of that water until your kidneys have created an equalibrium in your body. If you weigh yourself after you eat a lot of sodium in any given day and don't drink enough water, your weight will "seem" higher to you because of the excess water you are holding to flush the excess sodium out of your body. Drinking excessive water will not necessarily cause a sodium deficiency but may cause water intoxication if you drink too much in a short period of time, which is fatal. I have had 3 kidney stones in the past and learned that drinking the recommended amount of water daily will keep the kidneys flushed and reduce the crystalization of minerals and other materials. The kidneys are powerful organs in our bodies that we must take care of.

Ty for all the responses. Becky really made good sense to me.

That's a very good answer indeed. Thank you.

Water soluble vitamins can have a marked impact on urine color. These vitamins are not stored in significant quantities. Rather, the body uses what it needs and excretes the rest. Riboflavin is notorious for causing this effect in urine. Another factor is the rate of absorption. Some vitamins such as vitamin C have a limit to how much the body can absorb at one time. If you are taking mega-doses of water-soluble vitamins, you might not be receiving the complete health benefits they offer.

It is not related to the amount of water you are consuming. Water does not "flush" out more. It has to do with the body's need. If the body needs the nutrient or if the body's stores are already filled. Then the extra is exreted. While the same amount of nutrient is excreted, the color of your urine will be lighter when more water is consumed because of the dilution factor.

The glass and pool are not continuous processes. Actually you are mentioning a dilution process between two stationary cases.
There is a material balance in the continuous process.

If you drink more water, your urine will be lighter in color, regardless of whether you take a vitamin or not. If you've eaten something that colors your liquid waste, drinking more will dilute it so there's less color, but that doesn't mean it's "flushing" anything. The same amount of color in a larger amount of water looks lighter. If you want to see it at work, take two large pitchers. Put 8 cups of water in one and 12 cups in the other, and dissolve one vitamin tablet in each. The fuller pitcher will look lighter in color, but there's the same amount of vitamin in each.

So I guess the answer to your last question is yes. Drinking less water means the materials are in higher concentration in that sample.

The water isn't flushing out the vitamin. The body is already excreting what it can't absorb, if I remember my vitamin lore correctly. You're possibly diluting that color by drinking more, but I don't think you're flushing anything extra out of your body by drinking more water... it would be excreted regardless, you're just seeing less color because you're producing more urine and therefore more fluid is excreted.

You can demonstrate this by adding food coloring to a small glass of water. The more water there is, the less color shows in the water. Add a drop of food coloring to a shot glass, it's intensely blue... add it to a pool, and it doesn't show. No difference in the amount of food coloring.

What it amounts to is this: Our bodies are really terrible at absorbing the vitamins from a premade vitamin supplement. You're pissing away those expensive vitamins.

Explain one thing then.
If I take multivitamin that day
If I drink 8 glasses of water - urine is yellow
If I drink 12 glasses of water - no colour.

Where did the colouring Vitamin B go?
What is the cellular mechanism that retains salt in there?
Do materials transfer from high concentration to low concentration?

There is a great deal of nutrition misinformation on this thread. So first let's address the original question and then all the errors.

Original Post: You are not asking about extreme situations, just about some basic functioning of the body. Let's assume with the water in food + 8 cups of additional fluid daily puts "person X" meeting hydration needs for the day. Then "person X" increases fluid intake to 16 cups. This amount of extra water would not "flush" sodium out of the body or put person X in risk of sodium deficiency.

Errors in this thread...
Drinking more water does "not" flush sodium or extra vitamins out of the body.
Drinking extra water does not decrease water retention.
Caffeine in beverages, cabbage, cranberry juice, cucumbers, celery does not stop water retention nor do they flush sodium from the body.

Hope this helps clarify...

It does purge extra vitamins. Every morning I take multivitamin. My urine colour is usually yellow all day. But if I drink "lots" of water, I reach colourless, clear urine before night.

Salt is in equibrium between cells and body fluids (blood). As you put more pure water in the equation, the sodium equilibrium shifts to your blood stream and then filtered and thrown away in your kidneys. I think human body physical chemistry is more complicated than that but there is a truth in what the original poster claiming.

I never have heard that before...eating cucumbers, celery, etc.
I love those as a mid-day snack.

The quick remedy for stopping water retention is by water. This is because a water retention problem normally surfaces when our body gets dehydrated. Increasing intake of caffeine ( A known diuretic) can stop water retention. Also, eating cabbage as salad or soup & drinking cranberry juice will also stop water retention. (Ocean Spray Diet Cranverry with only 2 sugars)
Exercise on a regular basis. It will help flush out the excess water and salt from your body from the body, as a part of sweating and increased urine flow. It will also help in reducing swelling in the body parts, which might result from water retention, as it helps excrete extra salts from the body.
There is such a thing as water intoxication so 8 glasses of water a day is sufficient, If you exercise, the weather is very warm or you take meds that can cause increased thirst you may need a couple of glass more. eat high water foods on warm days like cucumbers, celery, etc.

NO. It's a common myth, but your body does NOT work like a toilet. You cannot "flush" anything by drinking extra water. As long as you are not clinically dehydrated, your kidneys can/will remove excess sodium in due course.

drinking increased water doesn't really flush sodium from the body, it just helps keep the percentage of sodium where it should be.

if you have low body levels in general, ask your doc. it could be a medicine or a symptom of something else.

Does drinking an increased average daily water intake carry sodium out of the body and potentially increase ones need for sodium?. For example if someone drank a gallon or so a day and fallowed a low less than 1500mg of sodium diet would the excess water carry sodium out of the body and thus put the person at risk for sodium deficiency or does increased water not flush sodium from the body?

I know acute over consumption of water can dilute blood sodium and cause hyponatremia but I'm talking long term and not dilute blood levels just low body levels in general.
