if you try to drink a large amount of water all at once, why does your kidneys flush the excess fluid out?

Your Body can only consume up to 8 ounces of water per hr. Since your body can only consume this amount there is no othere place for the liquid to go other than to have your body dispose of it. That is why when people drink a lot, the go to the bathroom more often.

Excessive water intake is called psychogenic diabetes insipidis.  The only real problem is you will have to pee a whole lot, and you could make your blood hypotonic or even cause dumping syndrome in your intestines.

This sounds silly but, water drink lots and lots of water.

Your body will accumulate water in order to dilute the excess salts you have taken.  This added volume of liquid in the blood stream is what increase blood pressure.  High blood pressure will then bring on all sorts of health problems from headaches to heart failure including brain damage, anuerisms, kidney failure as well as damage to other organs.\n\nCheck this out..\n\nhttp://www.medterms.com/script/main/art.asp?articlekey=3846

You probably have a kidney infection.  You should see a doctor.  Also try drinking more water and cranberry juice (not cranberry juice cocktail, but real 100% cranberry juice) to flush out your system.

Not too much longer because the liquid that you intake does not have a way to dispose of itself therefore the fluid just builds up all over your body.  Slowly our body starts to shut down.  Its a very painful death.

This usually is a sign of dehydration.  Drink lots of water.

Basically add the water lost through diarrhoea to the water lost through normal peeing and that's more water lost than usual therefore it needs to be replaced. When you pee it's perfectly normal therefore your body can handle the amount of water lost but diarrhoea isn't part of your body's normal digestion process therefore it's excess water that's lost.\n\nWhat happens when you get diarrhoea is your body has some sort of virus or bug or just something that it does't like therefore the digestive system (which is the system that gets rids of wastes and your body's toxins) will work faster than normal to get rid of that substance. Usually when digested food gets to the large intestine (the part right before your anus which is where the poo comes out) it absorbs any excess water and produces "normal consistency" poo. However because your entire digestive system is working faster than usual the digested food just kinda "zooms" through the large intestine without time for it to absorb the water therefore it comes out more "watery" than usual. Because this water was not absorbed into your body when it should have been, you will be lacking water which is why you need to drink plenty of water to replace it. \n\nHmm... does that make sense? Lol.

This is a diuretic which means it helps the body excrete more fluids. Last time I checked the process of eliminating excess fluids through the kidneys were the same for males as for females so obviously a male can take this drug. Meantime if you had any sense you would lay off the protein drinks, you are headed for long term damage.

water retention or edema...is a condition where your body holds onto the water reserves in your body, for various reasons.  You may be dehydrated, have liver or kidney functioning problems (your waste system may have something wrong with it), it comes from many things.  Women tend to retain more water than men, because water rentention is also due to fluctuating hormone levels, which happens during your period.

Before you seek any advice on how to balance your electrolytes, you should get your electrolytes checked. Have your doctor run a chemistry profile first. Sometimes, drinking a lot of fluids is your body's way of telling you that you need more fluids. Sometimes, it's a sign of a serious problem, though this is rare so don't get freaked out. Get more informed, and see your physician.

drinking a lot of fluid??  Diabetes??

Get background here: http://en.wikipedia.org/wiki/Polyuria\n\nNow water polyuria is caused by excess water in the body.  If your body is holding too much water, your kidneys will kick into gear and get rid of it.\n\nOsmotic polyuria is caused when your blood has a very high osmotic pressure, perhaps due to excess salts or ions in your blood.  When the osmotic change is detected, your kidneys kick into gear and start releasing lots of water to try to balance the osmotic pressure between both barriers.\n\nIn essence, what happens in both situations is the same: it relates to pressure.  Too much water or excess ions will create pressure on the kidney membranes, which activates renal activity and ergo, urine.

Water retention can be caused by a malfunctioning of the kidneys. However, in most cases it is not a signal that you have kidney problems. Water retention can be a sign of renal hypertension, high blood pressure or heart problems so a check up with your doctor could help eliminate some worries. Diuretics are used to treat virtually any disorder in which there is an excessive build-up of fluid in the body. They may also be used to decrease high blood pressure (hypertension) and to treat overdosage of certain drugs.

If the kidneys shut down, the body has no way to filter and then pass it on to the bladder. The "dirty" fluid can not be removed from the blood which is very dangerous (deadly). The kidney could stop working for several reasons. Some of the common ones is because of heart, artery or blood pressure trouble. A lot of heart patients end up on dialysis to filter their blood of the toxic fluids that the kidneys can't get rid of. Kidney disease, Lupus and other systemic conditions can also cause renal failure. Hopefully there has been some testing to determine the exact nature of the problem so treatment can begin.

Unquenchable thirst, also called polydipsia, occurs when the patient is dehydrated, or when the thirst mechanism is deranged, ie "psychogenic polydipsia" which is a psychiatric illness.\n\nDehydration can occur from water deprivation, or from excessive water loss.\n\nWater loss is mainly urinary.\n\nThere are two main reasons why the body would produce huge amounts of urine:\n\n1. Diabetes insipidus - this is NOT what people mean when they say "Diabetes". That disease is diabetes mellitus. Diabetes insipidus is when the body is unable to form concentrated urine (either through lack of secretion of anti-diuretic hormone, or lack of efficacy of it as may occur when taking lithium), leading to large volumes of water loss.\n\n2. Excessive amount of a solute which the body is getting rid of, eg, glucose in the case of uncontrolled diabetes mellitus. In this case the kidneys just flush lots of fluid through.\n\nBut water loss can also occur from the gastro-intestinal tract, ie vomiting and diarrhoea.\n\nExcessive sweating will also cause thirst.

Normally, if you drink something that is not 100% water you wouldnt count it because the ingredients will affect your metabolic system by altering your hydration/dehydration levels.  On top of that you are presurring your kidneys into more work when water just helps them.  Unless its water, dont count it.
