Water and Kidney Function

Water and Kidney Function

A lack of water for the kidneys can lead to critical regulation issues

The kidneys are located on either side of the spine at the bottom level of the rib cage. The kidneys are one of the most life-sustaining organs in the body where the filtering process of returning 200 quarts of fluid every 24 hours is crucial in making the body function properly. The urine stays in the bladder for 1 to 8 hours before it is released.

The Importance of Water
Water intake is an important element that affects kidney function especially since the body loses water on a daily basis so it must be replenished. The kidneys filter approximately 120-150 quarts of fluid per day and approximately, 1-2 quarts are expelled by urination and some are recovered by the bloodstream. This is why water is necessary for the kidneys to function since it’s necessary to filter out toxins on a daily basis.

If the kidneys do not receive enough water to function, waste products and excess fluid build up inside the body which can lead to critical regulation issues. One of the functions of the kidneys is to regulate the body’s salt, potassium, and acid levels. A key component of the kidneys function is that they produce hormones which stimulate red blood cell production so if it’s inadequate, other problems will ensue. Other hormones the kidneys produce are important as well since they help to regulate blood pressure and calcium metabolic function.

The kidneys are so valuable to the body that without having functioning kidneys, death would occur. Check out what healthy hydrated functioning kidneys are responsible for in this section of the article, Why are the Kidneys So Important?

Signs of Kidney Disease
When kidney disease occurs, it usually affects both kidneys due to the inability for the kidneys to filter blood and as a result, wastes and excess fluid can build up in the body. With certain diseases, water can either irritate or improve kidney function. If you have cardiovascular or other problems, your body might have difficulty balancing the fluid levels in your body. Drinking too much water can lead to diluted sodium blood levels or hyponatremia which could lead to dizziness, confusion, or death if it’s not noticed or treated in a timely manner.

On a daily basis, our bodies seek balance as it responds to changing sodium and electrolytes in the bloodstream by increased or decreased blood volume. If your salt intake is too high, the excess salt is released in the urine. If you suffer from kidney disease or another systemic illness, the body’s inability to deal with the sodium can lead to high blood pressure. Therefore, drinking more water can cause effects like swelling in the body which makes it harder for your heart to push blood throughout the body due to increased volume and pressure in the blood vessels

6 Reasons to Drink Water, It’s no magic bullet, but the benefits of water are many, on WebMD water plays a key role in maintaining optimum health. Drinking the right amount of water for your body while taking your activity or inactivity into account is necessary to get the right balance of fluids in your body. The amount of water each person should drink varies based on age, climate, exercise intensity or inactivity, pregnancy, and illness. Water actually helps the flow of blood to your kidneys to assist proper kidney function whereas severe dehydration can lead to kidney damage. If you drink too little water, you might also be at risk for kidney stones according to the WebMD article.

The main toxin in the body is blood urea nitrogen, a water-soluble waste that can pass through the kidneys so that urine can be excreted. This is why your intake of fluids has to be adequate. Urea nitrogen is a waste product that is created after you eat. As the liver breaks down the protein in your food, it creates blood urea nitrogen or BUN. Healthy kidneys will flush out BUN from your system through the urine. Unhealthy kidneys have difficulty removing BUN from your body so more of it is left in your blood. A blood urea nitrogen test or BUN test will determine how much waste product you have in your bloodstream. If the test comes back abnormal, then your kidneys or liver may not be working properly.

Whether you have healthy kidneys or unhealthy kidneys due to disease, determining how much water to drink is the key to maintaining homeostasis or balance in your body.
