Healthy Kidneys and the Role of Water

Drink plenty of clean water.

The human body is made to be self-healing. Some say it also "ages," but to me that means we let it wear down by not giving our bodies what they need to thrive. Good health not only makes us feel stronger longer, but it also helps our pocketbooks - saving us money on doctor visits, medications, and health insurance.

Although it doesn't make sense to withhold good health from our bodies, we do it all the time. Indeed, some of us take better care of our vehicles than we do our bodies. Knowing something about how vehicle engines work helps us to pick a good mechanic and also encourages good maintenance practices. Just so, knowing something about how our bodies work can help us choose a good doctor or health practitioner and can certainly help us treat it better. Starting with the role of water in general, this hub will move to the specific way in which water helps clean the blood - our body's transportation system.

Role of Water in the Human Body

The role of water in the human body mimics its role in nature, with its primary contributions being cleaning, transportation, and conduction:

  • Water washing in and out of cell walls pulls out wastes and puts in nutrients, keeping cells healthy and clean.

  • Water moves all kinds of nutrients, carriers, warriors, and wastes throughout the body. Water plus its carriers is called blood.

  • Electrical messages, by which our body communicates with itself, are conducted through the medium of water, which enhances the capacity of the nerves that send them. This is why the brain contains so much water (77%).

  • Water also keeps our bodies plump and well lubricated. People with too much water bloat up (edema). People with too little grow thin and wrinkled (dehydration). Both conditions either affect or are caused by unhealthy kidneys.

Kidneys are located behind the other abdominal organs.

Role of Kidneys in Human Body

The kidneys are the organs responsible for cleaning the body's blood. They have three main functions:

  1. To clean waste products from the blood and get rid of them.

  2. To balance the salts in the body, keeping the makeup of the blood liquid - similar to that of the ocean (from whence we originated) - and equalizing the blood pressure.

  3. To adjust the pH of the blood, keeping the body slightly alkaline, rather than acidic. This helps its beneficial bacteria to function properly, and keeps the mucous walls of organs properly plush (rather than eaten away, like acid does). It also prevents most of the harmful microorganisms from reproducing, since most of them need an acidic environment to do so.

Healthy Kidney Team/s

The kidneys work as a team with other organs, like:

  • The large intestines that reabsorb water from indigestible foods, which keeps the body hydrated and helps the kidneys keep a good salt/water balance.

  • The pancreas that creates enzymes to break down old and malfunctioning body cells, which are washed into the bloodstream and sent to the kidneys to be eliminated.

  • The spleen and bone marrow, which produce lymphocytes and leukocytes (white blood cells) to attack and kill invading bacteria and viruses, and to remove dead cells and foreign bodies. The residues flow through the bloodstream to the kidneys to be eliminated.

  • The lungs and digestive system to keep the blood alkaline (oxygen helps alkalize too) and the bones, to which the kidneys turn for calcium when the blood is too acid.

How a Healthy Kidney Functions

There are more detailed descriptions of how the kidneys work in the links below. Here is a brief description that you can match with the diagram on the right.

Blood enters a kidney through the renal artery (3) where it spreads out into a network of capillaries (2), each network with its own medulla (1) - a collection of tubules - capped by its own "working space" called a nephron (13). The capillaries filter out the larger, healthy blood components that will go back into the blood, and they send the finer blood to the nephrons, where it is checked for stasis.

If there is not enough liquid, more is added. If there is too much, some is taken away. If there's too much acid, it's made more alkaline and vice versa (to keep the pH balanced). Then the discarded liquid and wastes are sent through the medulla tubes to a larger capsule, the renal pelvis (6), where urine (as it has become) collects to be forwarded through the ureter (7) to the bladder. The bladder collects urine from both kidneys and, when full, expels it from the body.

The newly cleaned and refreshed blood, meanwhile, flows back into the bloodstream via the renal veins (4). In this way the kidneys continually clean approximately 20% of the blood pumped through the heart.

Why Two Kidneys?

The main reason we have two is to keep the workload balanced. Our lives switch between being extremely active, when both kidneys need to function fully, and being more relaxed, where the kidneys can relax a little too. On an average day the kidneys reclaim about 1300 grams of sodium, 400 grams of sodium bicarbonate, and 180 grams of glucose.

There is a slight benefit to the relative positions of the kidneys as well. The right one is located slightly lower than the left, near where the large intestine starts. The job of the large intestine is to reabsorb water from indigestible food we eat, so it can be eliminated as a semi-solid. This extra water mostly goes into the bloodstream, but some also migrates out into the cells around the large intestine, where it is picked up by the right kidney. Both kidneys are located in the abdominal cavity, where most of the body's digestive processes take place, where the water/salt and pH balance are most strongly affected.

The large intestine touches nearly every organ.

Typical Kidney Problems

  • Too thick blood and the formation of kidney stones - Comes from not drinking enough water. In order to make the blood liquid enough again, the kidneys take out salts and minerals, which sometimes harden into "stones" prior to excreting them through the ureters to the bladder.

  • Blood too acidic - When we eat too many animal products or drink too much coffee and other acidic liquids, the kidney changes the pH back to its stasis point by sending a chemical message to pull balancing salts from tissues. Blood that is too acidic will eat at the lining of organs, including the kidneys.

  • Overabundance of toxins - Bacterial wastes flowing through the bloodstream to the kidneys for filtration often carry live bacteria and viruses with it. If the blood is slightly acidic as well, these bacteria can proliferate in the kidneys and create disease there.

  • Pressure by constipated colon - A colon that's constipated increases in size, pressing against neighboring organs and preventing them from functioning properly. The ureters - the tubes that transport urine from each kidney to the bladder - are located close to the colon and can be blocked by an expanded colon. Urine then backs up in that kidney, which is very painful.

Maintaining Good Kidney Health

Tuning into the needs of your body is a great way to become healthy. Hatha yoga taught me what a relaxed, tuned-in body feels like, and how to notice it the minute something was off. From there I learned to question, research, experiment to see what my body liked best in terms of food, stress levels, attitude, and exercise. Now I'm 60+ years old and nearly as healthy as I was as a young adult.

In order to trust your body, it's important to experiment and even document its functions and reactions to the things you try as you are learning. Don't try to "make it work." It already knows how to work. Because each person's body is different, the following suggestions are for you to check to see if they fit you:

  • Start noticing how your body feels day to day. If it wants water, give it water. If it's restless or sluggish, give it exercise. If you're falling asleep at the computer, take a nap or go for a walk.
  • Drop any old obligations you're carrying that don't feel joyful anymore. Let the past go. Clean it out. This is the attitude most commonly associated with kidney problems.
  • Drink less alcohol and coffee, no soft drinks, more water - good clean, i.e. filtered water. Add a sprinkle of sea salt to your water to keep the salt/water balance and to take away some of the acidity most drinking water has these days.
  • Clean out any blockage you have in your colon. If you are easily constipated, then change what you eat.
  • Avoid GMO foods or meat that was fed with GMO grain mixes. More and more studies are emerging that show severe negative effects from GMO's.

Remember that your body knows how to function and take care of itself beautifully. Your job is to do what feels good to it, instead of resisting the changes that let it be healthy: Eat well, stay joyful, exercise in a fun way, drink lots of water, keep yourself clean inside, and appreciate the body you have.

I absolutely love that you say, "don't try to make it work" and "let the past go". Fantastic suggestions. What a glorious tribute to meloncauli. I didn't realize that kidneys helped regulate the ph of our bodies. I'm notoriously trying to ignore when something is wrong - I hate going to the doctor! Very interesting - Voted up -K

This was a very well done compendium on the kidneys and their functions in the body.

I agree that when the kidneys are working they do a great job. Unfortunately as we age the kidneys are one of the first organs that start to fail, or don't work efficiently. This is especially true in the elderly.

A lot of the kidney problems start when the heart doesn't has problems and it doesn't pump the blood the way the body needs it. The kidneys then are at the mercy of the heart, and can not do the one hundred percent of their job.

Additionally with the thousands of drugs out there many of the organs and messengers are doing more work than they do in a drug free body. Diuretics are like the mainstay of the doctor's prescription kit, and they are especially useful for edemas.

Unfortunately, diuretics are hard on the kidneys, and many times the kidneys will fails while trying to reduce the edema with heavy diuretics. My lay opinion is that this happens because the doctors don't really know what caused the edema, so they just shotgun the malady with diuretics. Any stay in the hospital increase the chances of getting a bug, and then you are filled with antibiotics, sometime they give a string of them. This is all hard on the body, and the organs.

The other thing that I have seen doctors have problems with is changing the acid to alkaline ph. They don't seem to know how to do it.

I believe that many of the drugs are worthwhile, but very few of them do more than try to treat the symptoms. To really return a body to its healthy condition, you can't shotgun, and just treat the symptoms. You need to get to the root cause of the problem.

In many cases, I believe that the body is prevented from fixing itself because it was interfered with by drugs.

The body and the brain are amazing but far from being a perfect design.

I totally agree with you ib. And I'm with you, too krsharp05. I don't go to doctors, specifically because of the drug issue. I read a book once by a medical doctor who had a serious case of arthritis - so bad that she couldn't get up out of bed. She eventually healed herself, but with macrobiotics, not anything she'd learned in medical school or through her practice.

In her book she talked about how influencial the drug companies are in medical schools. They finance research and poo-poo or suppress independent research that doesn't agree with theirs. They give massive grants to medical schools, such that now the majority of a doctor's training is on how to prescribe drugs - what they are and what they do and when to give what. I watched how doctors handled the aging of both of my parents, and it was all with drugs.

Thanks for the reply, and I believe we are looking at this with the same viewpoint.

The medical school aspect that you mentioned about learning how to prescribe, can almost be done by the lay person using the Internet. The protocols, and the drugs for most maladies are there for the reading.

There's so much information on the Internet we can use these days. The same is true of good health maintenance info. And the same caveat goes: Check with your body as you read. It will tell you what makes sense for you.

Oddly, I was just walking back from Starbucks and thinking I should stop trashing the medical profession. They do so much for so many people, including helping those who trust them more than they trust themselves.

I suffered from a painful kidney infection years ago, but didn't realize what it was until I went to a doctor for treatment. Now I understand the signals my body sends and make the necessary adjustments to deal with a variety of symptoms. That's saved a lot of $$$ over the years. Voted up, useful and interesting.

I sure am glad you survived it, Linda. Sounds like it provided some great learning for you, in addition to saving you money.

If you or anyone else gets a chance to read it, the front page of the New York Times today has an interesting article on doctors charging 3 times more for drugs that patients pick up in their offices, rather than at the pharmacy. They're charging the insurance companies these extra costs, so the patient never knows, and the insurance companies are getting ticked off.

Good luck Meloncauli. I'm glad you found it helpful. Might I suggest purchasing a water filter to clean up your tap water? Long term it will be healthier and cheaper than buying bottled water forever.

This is important information you have shared. We often takes for granted our two little kidney 'beans'. My best friend had serious kidney issues and finally had to have one of hers removed. It was a scary time as she was very ill and we almost lost her. Thankfully she was airlifted from Okinawa to Fitzsimmons and was well cared for. She is living today with one healthy kidney. Because of her struggle to survive, our family has been more vigilant about taking steps to keep our kidneys functioning well.

Well done, informative hub. Voted up. Congrats on hub of the day.

Very useful hub! After going through a major illness I agree that you really have to listen to your body and constantly give it what it needs. You are right that it is a bad idea to just deal with things. I never thought about the fact that something as simple as constipation can have a negative effect on the kidneys.

You bet your life, healthylife! Here are the organs that constipation can impair, depending on its location: Kidneys, liver, stomach, pancreas, spleen, adrenals, appendix, prostate. The large intestines come into contact with each one of them. And that's not to mention the major nerves and arteries/veins in the lower back that can be and are often blocked! Constipation plays a HUGE role in disrupting one's health.

Thanks CCahill - Yes, I believe the body was made to keep itself healthy in perpetuity. We, ourselves, get in the way of it by not listening to its messages, believing others instead of our own intuition, eating badly, enduring too much stress, and even by mocking ourselves.

I will be 62 years old next month. I don't get headaches, don't have digestive problems, barely get colds anymore, have good blood pressure and clear arteries, and have a flexible body. I haven't been in a hospital for about 30 years, except for my parents (both gone now) and carry no health insurance. I don't need it. I also keep a good, healthy attitude about my life and prospects, which translates into a healthy body.

An excellent treatment of the subject. You did a very nice job explaining what the kidneys are and what they do without making it too complicated for an average reader to understand. I was not aware of the issues you pointed out with acidic blood. It is a good thing for me that I am cutting back on my coffee....

I absoluotely love how you work in information about lisening to your body and letting it work. I am doing that more and more now that I have so many health issues and I am on tons of medications. I am hoping to cut the number of prescriptions in half in a year's time. Hubs like this are just what I need to help me along.

Great hub! I was just reading about distilled water before I logged onto HubPages. I never knew that distilled water is actually good to drink. I was always told not to drink it because it lacks minerals. After reading about it, I think people's kidneys would benefit from drinking it. Of course people would have to eat veggies and fruits to keep necessary minerals in the body. I'm going to give it a try and see how it treats my kidneys and body. Voted up.

Relationshipc 4 years ago from Alberta, Canada

Excellent hub! First off, I always try to tell my dad how important water is, and even though he feels better when he drinks it, he quickly stops and replace it with Pepsi. I should point him to this hub.

Second, I've been reading a lot about acid producing foods lately, and I've come to realize that many people live on acid producing foods. It's actually quite crazy. But I hadn't heard that "Blood that is too acidic will eat at the lining of organs, including the kidneys" and now that is stuck in my head and - I swear, my kidneys hurt.

Lastly, very interesting point about the constipation. I'm going to head down and get a glass of water right now.

Again, great hub.

Yes, FullOfLove. Think about how a kidney stone forms. It starts with an irritant, then builds up around it, becoming harder and ultimately more painful as it grows. Now translate that into a softer, more emotional form. There will have been an experience, then subsequent thoughts about the experience (brooding), then discussions about it and defensive reactions that build up and harden one's attitude about it (or the people involved) over time. What shows up in your body is a literal translation of the ongoing emotional attitude that triggered it.
