When drinking lots of water, does the blood osmolarity go up? Does blood volume go up as well?

on drinking lot of water the osmotic pressure of blood falls and excess water is then absorbed by the nephron of the kidney and excreated out to maintain the osmocity of blood

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

raises blood pressure\n\n Since sodium is the main ion that determines the amount of fluid in the blood vessels by osmosis, aldosterone will increase fluid retention, and indirectly, blood pressure.\n\nMimimize anything with Salt. Look at the nutrition labels and see the sodium levels. Try for <100mg

No.  \n\nDrinking a reasonable amount of water to excess amounts of water will no impact on muscle growth.\n\nSevere dehydration is a different story...and could have a negative impact.\n\nBut to answer your question, NO...drinking water does not make your muscles bigger.

drink a LOT of water, it really helps!

In a word, yes. Drinking too much water can lead to a condition known as water intoxication and to a related problem resulting from the dilution of sodium in the body, hyponatremia. Water intoxication is most commonly seen in infants under six months of age and sometimes in athletes. A baby can get water intoxication as a result of drinking several bottles of water a day or from drinking infant formula that has been diluted too much. Athletes can also suffer from water intoxication. Athletes sweat heavily, losing both water and electrolytes.\n\nWhen too much water enters the body's cells, the tissues swell with the excess fluid. Your cells maintain a specific concentration gradient, so excess water outside the cells (the serum) draws sodium from within the cells out into the serum in an attempt to re-establish the necessary concentration. As more water accumulates, the serum sodium concentration drops -- a condition known as hyponatremia. The other way cells try to regain the electrolyte balance is for water outside the cells to rush into the cells via osmosis. The movement of water across a semipermeable membrane from higher to lower concentration is called osmosis. Although electrolytes are more concentrated inside the cells than outside, the water outside the cells is 'more concentrated' or 'less dilute' since it contains fewer electrolytes. Both electrolytes and water move across the cell membrane in an effort to balance concentration. Theoretically, cells could swell to the point of bursting. \n\nFrom the cell's point of view, water intoxication produces the same effects as would result from drowning in fresh water. Electrolyte imbalance and tissue swelling can cause an irregular heartbeat, allow fluid to enter the lungs, and may cause fluttering eyelids. Swelling puts pressure on the brain and nerves, which can cause behaviors resembling alcohol intoxication. Swelling of brain tissues can cause seizures, coma and ultimately death unless water intake is restricted and a hypertonic saline (salt) solution is administered. If treatment is given before tissue swelling causes too much cellular damage, then a complete recovery can be expected within a few days.\n\nThe kidneys of a healthy adult can process fifteen liters of water a day! You are unlikely to suffer from water intoxication, even if you drink a lot of water, as long as you drink over time as opposed to intaking an enormous volume at one time. As a general guideline, most adults need about three quarts of fluid each day. Much of that water comes from food, so 8-12 eight ounce glasses a day is a common recommended intake. You may need more water if the weather is very warm or very dry, if you are exercising, or if you are taking certain medications. The bottom line is this: it's possible to drink too much water, but unless you are running a marathon or an infant, water intoxication is a very uncommon condition.

If your urine is clear every time, it will take about three days to fully hydrate all the tissues in your body. During this time you should expect to put on some weight (3-5 %). Don't look at this in a bad way. It's just weight you should have had all along. All the chemistry in your body happens in water. If the water gets saturated with waste products, the reactions slow down.\n\nAfter the three day period, you can slow up a bit on the water consumption; so long as your urine remains clear - you are hydrated. After your tissue is hydrated, the only ways balance your water is to cut back on water intake, or do something to increase the output (ie sweat from increased exercise or urinate more).\n\nWhile it is possible to drink too much water - it is rare. I have seen it under forced situations. What happens is the stomach lining is damaged (similar to how water logged hands ache). Usually, it only causes stomach ache and will make you throw up if you drink more.

Yes - the food you eat also contains water.

there is such a thing as water poisoning.  but for that you have to drink abnormal amounts of water(Gross amounts).\n\nas long as you are active and healthy, and eat a balanced diet, you can drink as much water as you want.  Most people don't drink enough water so look how lucky you are.\n\nI imagine that you will only have to worry about your water intake if your kidneys fail.

It depends on how much water you drank during the course of the day. The healthiest numbers as doctors say is 4-6 for well hydrated people but of course everyones water needs are different. Like If you do sports like football or baseball you need a lot of water but if you do swimming you don't because the water is all around you (even though you don't drink it because of chlorine and other chemicals).

drinking a lot of fluid??  Diabetes??

Your experience is interesting!  My first thought is as follows:  Vitamin D inhibits the renin-angiotensin system which plays a role in fluid balance (and therefore blood pressure) in the body.  You may have a genetic polymorphism (variation) creating a 'hypersensitivity' to vitamin D in this system.  However, if Vitamin D is really the cause of your thirst response, does exposure to sunlight also produce this effect in 5 or 10 minutes?  Lastly, I would expect it to take longer than 5 or 10 minutes for any vitamin D consumed to actually get into your blood stream.\n\nSo....if I haven't confused you by now, I guess the best answer I can offer is.... "that's a good question!"\n\nBest wishes and good luck!

Besides an absolutely normal pathology, you would expect all body fluids to be more concentrated.  This is because the osmotic difference between the surrounding water, and that in the body would cause wate to LEAVE the body.  This CAN happen via the skin, even thought the skin is fairly (but not entirely) waterproof.\n\nRemember that the process of osmosis causes fluids to follow the solute concentration, so a hypertonic solution such as very salty (sea) water would attract fluid, whereas hypotonic solutions (those devoid of solute) would effectively repel water.\n\nBottom line is water would be attracted out of the body tissues and blood into the surrounding sea water.\n\nNOTE THAT SURFGIRLTOGO's ANSWER ABOVE IS NOT CORRECT.  If the salt was INSIDE the red blood cells, the osmotic pressure differential would cause them to lyse and burst.  But as the salt water is OUTSIDE THE BODY, the water would be attracted OUT of the RBC's (and all other 9 types of cells in the blood) causing them to shrivel instead.

I think you mean BLOATED, and NO it's not good to drink too much water or gatorade. Try to stick with about 8-10 glasses of water a day, that's plenty.

Hello Porcelain,\n\nI checked a resource written by pharmacists and other medical professionals...\n\nhttp://www.nlm.nih.gov/medlineplus/druginfo/uspdi/202084.html#SXX19\n\nThere was no mention of water retention as a side effect.\nThis doesn't mean there is no relation between the two, it could\nbe very rare. Please check with your doctor or primary health care provider!\n\nWater retention, or endema, is generally not bad (unless it is in the lungs).  http://patients.uptodate.com/topic.asp?file=kidn_dis/4639\nHowever, whatever is causing the water retention should be addressed.  The cause of water retention can lead to problems in the kidney, heart, or liver.\n\nA doctor or health care provider can, by observation and ordering tests,  determine the cause of the water retention.  For example,\nblood or urine tests may be ordered  to check on the condition of the liver and kidney.\n\nAgain, I do not know if there is a relation between the two, or how serious it is.  Please consider this to be an aid in any discussion with your health care provider.\n\nHoping this helps some,\nJanice\n\nPS Feel free to email me if this answer doesn't make sense\nor if there are other questions.

Increase in body water is called fluid volume excess. the two types of fluid volume excess are \n\n1.      extracellular fluid excess (isotonic fluid excess) \n\n2.      intracellular water excess (hypotonic fluid excess) \n\n      a fluid volume excess may result from renal or cardiac failure with retention of fluid \n\n      increased production of antidiuretic hormone or aldosterone over load with isotonic  \n\n      intravenous fluids . the body attempts to compensate for fluid volume excess by \n\n      increasing the filtration and excretion of sodium and water by the kidneys and \n\n      decreasing the production of antidiuretic hormone \n\n                        \n\n1.      fluid volume excess® related to fluid retention, excess or hypotonic \n\n      intravenous fluid administration \n\n2.      acute confusion, altered through thought processes= related to \n\n                                    cerebral edema \n\n3.      activity intolerance, impaired gas exchange=related to pulmonary \n\nedema \n\n4.      risk for injury® related to decreased level of consciousness \n\n5.       risk for impaired skin integrity® related to edema \n\n6.      altered (cardiopulmonary) tissue perfusion related to reduced cardiac output with heart failure

Yes it does, that is why when you eat alot of sodium you hold alot of water and why more. The salt holds the water because it absorbs it and stays in your system. Also if you eat alot of salt you can get high blood pressure. Just think of a mummy when they put salt on them they don't stink are shriverl up so that is exactly what salt does in your body.
