Our daily metabolism requires us to replenish enough water every day. After water is ingested into the body, it is treated by the kidneys. After drinking water into the body, some of it will pass through the throat, esophagus and stomach, some will be absorbed by the stomach, and the other part will enter our intestines, helping the gastrointestinal tract to move better, promoting our excretion and maintaining the balance of intestinal flora. After being absorbed by the intestine, it will enter the blood and participate in blood circulation.
Generally, about an hour after we drink water, it will participate in the blood circulation process, transport it to various organs of the body along the blood vessels, and replenish water to various organs of our body. The residual water, toxins and garbage taken away during the circulation will eventually be filtered in the kidney with the blood circulation. The kidneys filter out excess water and toxins from the blood and excrete them through urine. The human body circulates and filters many times a day, and the kidneys are mainly responsible for the final filtering work.
We all know that uremia patients will do dialysis, and the principle of dialysis is to replace the kidney and help clear the blood and garbage toxins in the body. After our kidney is cut open, we can clearly see that it is divided into two parts, one is bright red meat, called renal parenchyma, and the other is cavity, called renal pelvis. As the name implies, the renal pelvis is the place where urine is temporarily stored. The kidneys work very accurately. After the blood reaches the kidney, the filter will judge the number of open nephrons by the blood flow. Each nephron consists of two parts, namely renal tubule and glomerulus. The glomerulus is responsible for filtering excess water and toxins to form urine, and the renal tubule is responsible for reabsorbing useful substances. Finally, the useless substances in urine will be temporarily stored in the renal pelvis, and will be excreted through the urethra after being stored to a certain amount.
Since water is filtered through the kidneys, will excessive water intake burden the kidneys? The kidney opens about a quarter of the nephron every day to complete the work needs. When we drink more water, more nephrons will participate in the filtration work. Therefore, drinking water at ordinary times will not harm the kidneys, but it is still very dangerous for patients with renal insufficiency to drink a lot of water for a short time, which may easily cause hypertension or edema.
The three most damaging drinking habits in daily life are: drinking water only when you are thirsty, drinking strong tea and drinks instead of boiled water for a long time, and drinking water only when you are thirsty. The water in our body has lost 1% of our body weight, and our body will be affected by water shortage, which will cause certain damage to our kidneys for a long time. Drinking strong tea for a long time will not only harm the stomach, but also increase the burden on the kidneys and cause harm to the kidneys. Some people often drink drinks instead of water. Drinks contain a lot of sugar, phosphate and other substances, which will cause the loss of calcium in the body, and the increase of calcium in urine will cause kidney calculi.
Generally, a healthy adult will eliminate at least 2500 ml of water through urination, breathing and other metabolism every day, so we can only take in 2000 ml to 3000 ml of water every day, which not only ensures the water demand in the body but also increases the burden on the kidneys. In fact, many friends with kidney problems are often due to insufficient water intake, rather than drinking too much water. Therefore, people with normal renal function should ensure the normal intake of water.
