Is it good to drink more water if you have kidney deficiency?

It is said that life is made of water and water is the source of life. However, everything has its limits. Drinking too much water blindly can cause many health problems. Especially for those patients with kidney deficiency, if they drink a lot of water blindly, it will inevitably increase the burden on the kidneys, which will cause kidney deficiency and affect the normal urination function. So is it good to drink water if you have kidney deficiency? What should you pay attention to when drinking water in daily life?

I don't know when the so-called health concept emerged, which is to drink eight glasses of water a day. Drinking more water can detoxify and flush the large intestine. In fact, drinking water like this is very harmful to the kidneys. In severe cases, it can cause kidney deficiency and inability to hold urine. Drink water in small sips, no more than three sips, leaving room for easy digestion and absorption. Modern people only want to be fast and drink a lot of water. As a result, a large amount of cold water is stored in the stomach, which is either urinated out or stored and has no way to become body fluid. Drinking water principles: drink when you want to and when you can. Analysis: Mao Wei, chief physician of the nephrology department of Guangdong Provincial Hospital of Traditional Chinese Medicine, said that the amount of water you drink varies from person to person, and you cannot dogmatically follow "eight glasses of water a day." People in good health just need to grasp the principle of not feeling thirsty and not feeling bloated or uncomfortable after drinking water. If you are thirsty and want to drink water, and you can drink it, feel free to drink it. People with poor stomach, kidney, heart, and liver function must drink water in proportion to their intake and determine the amount of water they drink based on their sweat and urination. Drinking too much water can cause edema or even water poisoning. For people with poor renal function and edema who are undergoing detumescence treatment, the amount of "output" is greater than the amount of "intake". People with urinary tract infections should develop the habit of drinking plenty of water to fully utilize the "flushing" effect of water on the urethra and avoid bacterial growth. Patients with kidney stones drink more water than ordinary people in order to speed up the excretion of urine and excrete the calcium and debris that have precipitated and accumulated in the kidneys to prevent the formation of stones. In life, some people are particularly thirsty and love to drink water, while some people are not thirsty easily, and will feel bloated and want to vomit if they force themselves to drink water. From the perspective of traditional Chinese medicine, the latter belongs to spleen and kidney deficiency. People of this type usually have physical characteristics such as abdominal distension, fear of cold, dampness, diarrhea, etc. At this time, there is no need to force yourself to drink water, lest the spleen and stomach cannot transport and transform water, which will turn into dampness, dryness, and phlegm. "Modern people only want to be fast and drink water like a guzzler. As a result, a large amount of cold water is stored in the stomach, which is either urinated out or stored and has no way of becoming body fluids." This statement is incorrect. Because after water enters the stomach and intestines, it will be absorbed into the blood and filtered by the kidneys to form urine. It is not the case that "you eat it and then poop it out." “Drink water in small sips, three sips or less, leaving room for digestion and absorption.” This is worth promoting, and drinking water in small sips is more conducive to the body's absorption.

2. "A glass of water before bed can prevent sudden death from heart disease." Diseases such as angina pectoris and myocardial infarction are caused by high blood viscosity. When people are asleep, they lose water in their bodies due to sweating, which causes a decrease in the water content of the blood and makes the blood more viscous. But if you drink a glass of water before going to bed, it can reduce the viscosity of the blood and reduce the risk of sudden heart attack. Drinking water before bed can prevent sudden death? Useless! Analysis: Chen Riximing, director of the Department of Cardiology at the Third Affiliated Hospital of Guangzhou Medical College, has no medical literature or statistical data to prove this point. Myocardial infarction and myocardial infarction are caused by rupture of coronary artery plaque. If the viscosity of human blood is too high and the blood is too concentrated, it will indeed accelerate the rupture process. However, it should be taken into consideration that most patients with coronary heart disease are elderly people, and the proportion of patients with prostate enlargement is high. If they drink too much water before going to bed, they will always want to go to the toilet, which will affect their sleep quality. Some people have long-term coronary heart disease, myocardial ischemia, and poor heart function. If they drink too much water before going to bed, blood return will be poor, which will increase the burden on the heart and cause shortness of breath. People with poor kidney function will cause excessive kidney function due to drinking a lot of water, aggravating renal failure. Unless you are doing strenuous exercise, your body will not be severely dehydrated if you drink water at a normal frequency and amount. Just drink when you are thirsty and let nature take its course. If you do a lot of outdoor activities and sweat a lot under the sun, you should pay attention to hydrating during the day. In addition, people do lose water due to sweating when they sleep, about 200 to 300 ml on average. But under normal circumstances, the human body can regulate the water balance on its own. The loss of this water will not cause any harm to the body due to the compensatory function of the kidneys. During the dog days of summer, everyone turns on the air conditioner when sleeping, and just make sure to maintain the humidity of the environment. To prevent heart attacks, we need to remove the inducing factors and change our unhealthy lifestyle. Control blood pressure, blood lipids and blood sugar through medication. Pay attention to exercise, quit smoking and drinking. This is the most effective way to prevent sudden death.

3. "Drinking cold water after a meal is equivalent to getting cancer." Cold water can immediately turn the newly absorbed oil into a solid state, thus affecting digestion. So drink hot drinks after meals. Drinking cold water after meals is not good for digestion. Analysis: Mao Wei, chief physician of the nephrology department of Guangdong Provincial Hospital of Traditional Chinese Medicine, does not advocate drinking cold water after meals, because cold water will affect stomach digestion, but it is an exaggeration to say that doing so will cause cancer. The statement that "cold water can immediately turn the newly absorbed oil into a solid state, thus affecting digestion" is totally unfounded. The stomach has gastric juice that can promote digestion and absorption, and the food that enters the stomach will be chewed in the mouth and processed by salivary amylase first. This situation cannot occur. 4. "Beverages should not be the first drink in the morning." It is best not to drink commercially available juice, cola, soda, coffee, milk and other beverages as the first drink in the morning. Some drinks are conducive to urination. Drinking them in the morning will not only fail to effectively replenish the body's lack of water, but will also increase the body's demand for water, causing dehydration in the body.
