Should patients with kidney disease drink less water or more water? What is reasonable?

Hello, I'm a urologist. Because the kidney belongs to the organ of urinary system, I am familiar with the basic structure and function of the kidney. Clinically, patients with kidney disease have a "thinking habit", that is, they are good at "how to eat", but they often ignore "how to drink" and pay insufficient attention to "how to drink". But in fact, "drinking" is as important as "eating". Sometimes, even "drinking" is more important than "eating"

For example, what should people with kidney disease pay attention to? The patient will answer with a smile: Doctor, I told you to have a "low salt, low fat+high quality and low protein" diet. I believe this is also the doctor's advice that nephrologists and urologists pay more attention to, so patients will remember it well. But when you ask patients if they should pay attention to drinking water, some patients will say: drink more water. I heard from the doctor that you said the same thing to others. Some patients seem to know more, and may say: Don't you want to drink more water properly? Only in this way can we discharge more body "garbage" and prevent the kidneys from having a greater burden? But some patients will say: doctor, you said I was edema, so I should drink less water.

Is it wrong for these patients to describe drinking water like this? Why do some patients say to drink more, while others say to drink less? Is the doctor's advice wrong? In fact, there is nothing wrong with the doctor's advice and the patient's hearing? So why do some patients drink more and some patients drink less? The answer is: both drinking more and drinking less will exist, depending on the patient's condition, that is, symptoms and signs! Don't worry, everyone. After I analyze it for you, you will feel something!

Let me tell you first: When can you drink more water for kidney disease? The answer is: if there is no "edema, oliguria and massive proteinuria", then you can drink plenty of water appropriately! Ensure that the 24-hour urine output is about 2000 ml. At this time, the excess metabolic waste in the body will be excreted with urine, so that although the filtration function of the kidney unit is reduced due to nephropathy, it can also ensure that more metabolites are excreted with urine and will not "accumulate" in the body.

The most important thing now is to tell you, under what circumstances can't kidney disease drink more water? The answer is: in any case of "edema, oliguria and massive proteinuria", you should limit the amount of water you drink and not drink too much. Why is this? Because "edema and oliguria" refers to the accumulation of too much water in the body, the excretion function of the kidney has been abnormal or decreased. In this case, drinking more water or replenishing more fluids will accumulate under the skin of the body, or in the organs and tissues of the body, or even in the chest and abdominal cavity. Because the chest is the location of the lungs and the abdominal cavity is the location of the digestive system, you can drink more water and accumulate water.

The situation of "massive proteinuria" has explained that excessive protein in urine is abnormal and why it is abnormal, because protein is beneficial to human body and plays an important role in maintaining the balance of internal environment, electrolyte and nutrition. If it is excreted with urine, the body will definitely be destroyed. In this case, the more water and urine you drink, the more protein you excrete with urine, which means the more running water in protein, which directly leads to your health.

At the same time, the most important thing is that under normal circumstances, edema, oliguria and massive proteinuria will generally merge or appear at the same time, so the more obvious these three symptoms are, the more you should limit drinking water in time and not drink more water.

Ok, now we know that when you have edema, oliguria and a lot of proteinuria, you can't drink more water. You need to limit the amount of water you drink. So how do you limit your drinking water? What are your skills? In fact, there are three convenient indicators to guide patients with kidney disease to drink! They are arranged according to "weight, urine volume and edema degree"!

Weight: on the premise of regular diet and no food retention, get up every morning and measure your weight on an empty stomach. If it increases, it means that you have more water in your body (friends should be careful not to be affected by the clothes you wear). You should limit the amount of water you drink at this time.

Urine volume: record the urine volume every time you urinate. How long is the urine volume recorded? Record the 24-hour urine volume! How to record it is simple. We use mineral water bottles and other bottles whose capacity we know in daily life, and then put urine in them, so that we can know how much urine we have at a time. After knowing the urine volume for 24 hours, calculate the total water consumption for 24 hours. If you subtract 500 ml from the total water consumption, the amount of water obtained exceeds the urine volume for 24 hours, which means that there may be excess water "accumulation" in the body and edema may occur. At this time, you have to limit the water consumption.

Degree of edema: This is a common and simple method. You can press the skin in front of the tibia every day. If the depression deepens or there are many depressions, it means that the edema is aggravated. You should limit the amount of water you drink at this time.

Other things to note are that in addition to drinking less water, foods such as sugar porridge and fruits are also foods with more water content, so avoid eating more. At the same time, salt should be strictly limited to avoid drinking more water because of thirst. Generally speaking, in the case of edema, oliguria and massive proteinuria, drinking water is a "prescient" mentality. Take medicine with a glass of water every day, and don't make up. At the same time, if you are thirsty, you can take a sip and control the amount of water you drink.

The above is my opinion on how to drink water for kidney disease. Although it is easy to understand, I will give you an analysis from a scientific and rigorous point of view. Here, I also remind everyone that it is very important to drink water well for kidney disease. If you drink it wrong, it will easily lead to the aggravation of the disease, especially for patients with oliguria and edema. Water should be strictly controlled. If there is too much water in the body, the volume load of the body will increase, the probability of heart failure and dyspnea will increase, and the electrolyte balance of the body will be disrupted. Therefore, we should recognize the harm, drink water correctly, reduce the medical burden, improve the quality of life and strive for an early recovery!

Water is an important part of human body, accounting for about 60% of body weight. Replenishing water in time is helpful to reduce the concentration of harmful substances in the kidney and has an important protective effect on the kidney. Getting enough water every day is very important for the metabolism of the body, because too little water supplement will reduce the amount of urination, which will lead to an increase in the concentration of toxic substances in urine. The kidney is an important organ for excreting water. For some patients with kidney disease, supplementing enough water is more conducive to promoting waste discharge.

There are many things that kidney patients need to pay attention to and care for, and the drinking water of different kidney patients is also very different. Only by adopting the correct drinking water method can the kidneys be effectively protected. The following is a detailed introduction of drinking methods and precautions for patients with different kidney diseases:

Why hydration helps protect the kidneys. Kidney is the main organ for human body to excrete water and metabolic waste, and it can excrete 3040g of solid metabolites every day. Because dissolving 1 g solute requires 15 ml of water, the daily urine output of normal people is 800 1300 ml. Even if the kidney compresses the concentration of metabolic waste to the maximum, the daily urine output is at least 500 or 600 ml.

When too little water is added every day, the urine volume will also decrease, which will lead to an increase in the proportion of urine and increase the burden on the kidneys. Therefore, we should pay more attention to hydration on weekdays to promote the excretion of metabolic waste in the body.

How should kidney patients replenish water? Patients with chronic kidney disease

Patients with renal insufficiency should drink plenty of water without obvious edema, because this can increase urine output and help excrete metabolic wastes and toxins from the body.

Nephropathy edema patient

Patients with renal diseases and edema, such as acute nephritis, nephrotic syndrome and pyelonephritis, should monitor their weight and urine volume every day. Drinking water should follow the principle of "balance in and out", that is, the daily drinking water amount is yesterday's urine amount +500 ml, but not more than 1000 ml. In addition, the moisture in food should also be counted, such as porridge, wonton and other foods with more water. When thirsty, you can drink a small amount of corn silk water, watermelon water or winter melon soup to help urinate and reduce edema.

Chronic kidney disease complicated with heart failure

If the urine volume of patients with chronic renal failure has been significantly reduced, the water consumption must be strictly controlled. Drinking water should also follow the principle of "balance in and out", and the amount of drinking water is also calculated according to yesterday's urine volume +500 ml. Drink more water before going to bed, and don't drink a lot of water at a time.

Patients with urinary tract infection

If you have urinary tract infection, you should get into the habit of drinking water regularly, because this can flush the urethra and prevent bacteria from multiplying in large numbers. For patients with urinary calculi, you can also drink plenty of water to facilitate the discharge of stones in the body. Generally speaking, as long as the amount of drinking water reaches 2500 ml per day, it can promote the rapid discharge of urine, thus discharging some calcium and impurities in the body and making the body healthier.

Patients with heart disease and patients with abnormal liver function and ascites should not drink more water. Patients with heart disease, especially those with heart failure, are prone to symptoms of systemic edema because of abnormal renal blood flow and perfusion function and unable to excrete water from their bodies. At this time, if you drink too much water, it will increase the burden on the heart, lungs and other organs, and even induce hyponatremia, nausea, vomiting and general convulsions, and even coma in severe cases.

Patients with abnormal liver function can't synthesize blood protein by themselves, and other reasons can also lead to edema. Therefore, after the osmotic pressure of blood is reduced, water is easy to accumulate in various tissues, and the phenomenon of hydrops in abdomen and thorax often occurs. Patients with the above conditions should not drink more water, because it will aggravate edema. Therefore, if patients with abnormal liver function have edema, the daily drinking water should be reasonably limited according to the edema.

How much water should normal people drink every day? Regarding the amount of drinking water, it is commonly known as "adding eight glasses of water every day", so it is not necessary to do it completely. According to medical data, the daily alcohol consumption of normal adults is about 2000 ml, generally not less than 1500 ml and not more than 2500 ml at most. Of course, the specific situation should also be comprehensively considered according to the environmental temperature, seasonal changes, and the amount of exercise.

Harm of drinking too much water We know that there is a limit to everything, and drinking water is no exception. Drinking too much water in a short time will also do harm to health. Drinking too much water will increase the metabolic burden, resulting in excessive water in the body can not be discharged in time. When a lot of water stays in the body, it is easy to cause edema. If the situation is serious, abdominal pain will occur. , but also stimulate renal function, causing renal function damage.

When the water intake is too high, the water flow of the kidney is greatly increased. At this time, although the metabolic waste in the body is diluted, it will also affect the detoxification function of the kidney, resulting in an increase in the burden on the kidney. In this way, the diluted toxic substances and excessive water can not be excreted in time, resulting in water poisoning. Water poisoning will seriously endanger kidney health, and it is more likely to induce dehydration and hyponatremia, leading to metabolic disorder, renal failure, frequent urination and urgency, weakness, decreased resistance and yellow complexion.

Drinking more water can not slow down the decline of renal function. A study in Britain and Canada shows that drinking 4 6 glasses of water a day will not slow down the decline of renal function in patients with kidney disease. Researchers said that although it is generally believed that drinking more water can delay kidney disease, there are few specific studies on the optimal amount of water to drink. Although the benefits of drinking more water have not been directly verified, more and more evidence shows that drinking more water can improve renal function by inhibiting the release of antidiuretic hormone.

According to reports, the research object of this randomized clinical trial is 63 1 patient from London Health Science Center and other hospitals in Ontario, Canada, all of whom have stage 3 kidney disease. You know, stage 3 patients will lose 70% of their kidney function. In this experiment, half of the participants were asked to drink more water (1000 1500 ml per day, depending on gender and weight), while the control group maintained normal water intake or reduced water consumption by 250±500ml per day.

The results showed that the group that increased drinking water did not slow down the loss of renal function. However, they found that increasing drinking water inhibited the release of antidiuretic hormone, especially in patients with low drinking water before. This study shows that for most patients with non-dialysis chronic kidney disease, increasing water intake will not prevent further loss of renal function, but it will enable us to focus on other potential treatment options.

Finally, never use drinks instead of pure water or boiled water to replenish water. Because phosphate and sugar in drinks can promote calcium deposition, when the calcium content in urine increases, it is easy to form kidney calculi. In addition, carbonated drinks also contain some substances that promote blood pressure and damage the kidneys, so drinking a lot of carbonated drinks will have adverse effects on the body.

Hello, Sannuo talks about sugar. Glad to answer for you!

Patients with kidney disease should choose to drink more or less water according to their physical condition. For most patients with kidney disease, the recommended drinking amount is:

The total daily water intake is implicit water loss-urine volume before explicit water loss. If the patient is not obviously dehydrated (vomiting, diarrhea or drainage, etc.). ), the daily fluid volume is 500ml of the previous day's urine volume. If the patient has a fever, the amount of hidden water loss (through the lungs and skin) will increase by 1 0-15% every time the temperature increases.

1 2 chronic kidney disease patients have no substantial damage to renal function, or the damage is slight, and the glomerular filtration rate is generally above 60m/min. Kidney friends who meet these conditions do not need to drink too much water, and as usual, they should consume at least 2000ml of water every day.

Drink less water: such as nephrotic syndrome and acute nephritis syndrome. When edema occurs; Acute renal failure, chronic renal failure and other conditions may lead to oliguria or anuria; Dialysis patients.

For example, normal people should drink at least 2000 ml of water every day, but the daily water intake of patients with mild edema is generally 1000 ml, and that of patients with severe edema is lower than 1000 ml.

You should drink plenty of water: when you have a cold, especially fever, diarrhea, dehydration, etc. High uric acid; Do a comparative examination; There are urinary calculi; Sweat too much It is best to drink more than 2000 ml.

The kidney is actually a small organ, but it is of great significance to human beings, because our daily metabolites are mainly excreted through the kidney. I think this is especially true for patients with renal failure, because the main purpose of each dialysis is to use artificial devices to remove metabolic waste.

At the same time, the kidney also has the function of reabsorption. Why? Mainly because urine is not all useless substances, such as glucose, amino acids, electrolytes and other substances useful to the human body are reabsorbed into the body through the kidneys. People can filter 180L liquid every day, but they urinate very little every day, about 1500ml. In addition, the kidney also has endocrine function, which can secrete renin, active vitamin D and erythropoietin. In order to let everyone know more about kidneys, I will share some related knowledge.

1. Should patients with kidney disease drink more or less water? In fact, it is not easy to answer this question, because nephropathy is a big concept, which includes glomerulonephritis, nephrotic syndrome, renal vascular disease, pyelonephritis and so on. Because the scope of kidney disease is relatively large, we can't completely think that patients with kidney disease should drink more water or less water.

Maybe everyone thinks that patients with kidney disease should control drinking water, but it is not necessarily so. Take pyelonephritis as an example. This is a urinary system infection. People with this disease have normal renal function, so there is no restriction on drinking water. On the contrary, patients with acute pyelonephritis should also appropriately increase the amount of drinking water, which can increase the amount of urine, thus flushing the urethra and promoting bacterial excretion.

However, for other kidney diseases, whether it is necessary to control drinking water also needs to be decided according to personal circumstances. For patients with obvious edema and decreased urine volume, the amount of drinking water should be reduced appropriately, otherwise it will increase the burden on the kidneys and aggravate the condition. If the patient's urine volume is normal and there is no obvious edema, in this case, just drink water normally. There is no clear regulation on how much water patients with kidney disease should not drink. If you don't need to control the amount of drinking water, you can consume 2000~2500ml of boiled water every day. If you need to control the amount of drinking water, you need to combine your own situation and you can't generalize. You can consult your own bed doctor for details.

2. What else should kidney patients pay attention to in their lives? In fact, many kidney diseases are chronic, and modern medicine is not easy to cure. In this case, personal life care is more important.

Patients with kidney disease should pay attention not to eat high-protein diet, although many of these patients are low in protein, mainly because high-protein diet will increase glomerular hyperfiltration and aggravate kidney disease. When the body is edematous, we should pay attention to a low-salt diet.

Many patients with kidney disease may also have hypertension, diabetes and hyperlipidemia at the same time. For such people, we must control them well, because these diseases themselves will accelerate the progress of kidney diseases.

Handwriting is not easy. If you think what you wrote can be praised, you can pay attention to it. If you have any questions, you can leave a message below ... kidney calculi, pyelonephritis, drink more water.

Other kidney diseases should drink less water, do not increase the blood flow burden of the kidneys, and rest more.

Should kidney patients drink more water or less water? How to drink water? Let's talk together today.

As we all know, the kidney is one of the most important organs in the human body. People have two kidney sources because they are very important to our metabolism. Even when the body has only one kidney, it can also act as a "chemical factory", allowing the body to continue to maintain normal physiological functions.

It cannot be ignored that water is the source of our life and has a very close relationship with the kidneys. For normal healthy people, the latest version of Dietary Guidelines for China Residents suggests that the total water intake per person per day should be within the range of1.5l-1.7l. ..

Drinking too little water will increase the burden of kidney excretion, even if the urine is concentrated. Therefore, it makes sense to drink more water. Some people here say that if you have kidney disease, should you drink more water or less water?

As we all know, the metabolites in our bodies and substances that can pose a threat to our health will eventually be excreted in the form of feces or urine. In this case, patients with kidney disease or people with poor kidneys should not drink too little water.

Doing so will reduce the excretion of metabolites in the body. In the long run, the body will accumulate more and more products, which is likely to cause harm to the whole health. How about drinking more water?

For people with renal insufficiency, or people with chronic kidney diseases, a large amount of water may increase the burden of renal excretion after entering the body. When you observe the color of urine, it is close to transparent color, which means that you drink too much water.

The best way is to drink the right amount of water and the right amount of water, which is a good way for the kidneys.

How should we choose water resources?

People with poor kidneys can choose low-calorie boiled water, tea, pure water and mineral water. It is not recommended to choose sweet drinks, salt water, etc. These two typical representatives will increase the burden on the kidneys.

There are many kinds of sweet drinks, such as carbonated drinks, fruit juice and milk tea. , are considered as a sweet drink. The biggest feature of this kind of beverage is that it contains a lot of sugar, which will not only increase the metabolic burden of the kidneys, but also be a fattening weapon for dieters. Whether the kidneys are healthy or not, it is not recommended to choose such water resources.

Salt water, for China people, can only be properly supplemented when the body is dehydrated seriously. In other cases, drinking salt water is not recommended, which will make the kidney unable to adjust the balance of water and salt, aggravate the risk of illness, and is not a good way to tonify the kidney.

I hope my answer can help you!

water

It is the source of life and closely related to kidney diseases. However, people have different views on how much water to drink every day. Some people say that drinking plenty of water will increase the burden on the kidneys and accelerate the decline of renal function; It is also believed that drinking more water can help to expel toxins and prevent kidney disease. It is true that for normal people, drinking plenty of water is a good habit and beneficial to health; But for patients with chronic kidney disease, it is not easy to judge whether to drink more or less. It may be useless to drink less, but if you blindly follow the theory of "eight glasses of water a day" according to your illness, I am afraid it will lead to great disaster. At this time, reasonable drinking is the key.

first

Patients with chronic kidney disease should learn to check themselves every day to see if there is edema in eyelids, depression in the front of tibia and ankle, and normal urine output. For patients with chronic nephritis, nephrotic syndrome in remission and early chronic renal insufficiency, if edema is not found, they should drink water naturally and normally, without deliberately limiting water, especially in the case of diarrhea and sweating in hot days. If they feel thirsty, they still don't replenish water in time. Long-term water shortage will lead to decreased renal perfusion, which is unfavorable. However, in the case of chronic nephritis, nephrotic syndrome complicated with edema, and chronic renal insufficiency leading to decreased urine output, you can't drink water as you like, because it can't be discharged after drinking, and water retention in the human body will aggravate edema and hypertension. For those with mild edema, the amount of drinking water can be slightly controlled; However, in the stage of diabetic nephropathy with a large amount of proteinuria, when nephrotic syndrome begins to appear, or the urine volume of chronic renal insufficiency is obviously reduced, the edema of patients is often serious, and even symptoms such as chest tightness, breath holding and abdominal distension appear. At this time, it is necessary to strictly control the amount of drinking water and adopt the principle of "living within our means". Generally speaking, you can use the urine volume of the previous day +500ml to roughly calculate the amount of drinking water needed that day. If fever, diarrhea, vomiting and hyperhidrosis occur, the corresponding water loss will increase. At the same time, don't forget that some foods, such as soup, porridge, fruits, milk, vegetables, fruits, etc., contain a lot of water, so we need to reduce the amount of drinking water according to the eating situation, so as not to aggravate edema by ingesting too much water. Of course, not all kidney diseases need to control the amount of drinking water. For patients with kidney calculi and urinary tract infection, you can let go of drinking water. At this time, drinking more water will help to remove stones and control infection.

in addition

There are still a few points to remind patients with kidney disease. First of all, fix the water cup and know how much water you drink a day. The second is to drink water at different times. Don't drink water immediately before and after meals. It is a good time to drink water after getting up in the morning and between meals. Third, don't wait for thirst to drink immediately, but develop the habit of drinking water many times with small mouths; Fourth, the diet should be light at ordinary times, and salty cooked food is easy to cause thirst, which is not conducive to controlling the amount of drinking water; Fifth, weigh yourself regularly. If you gain weight for unknown reasons in the short term, you should pay attention to whether there is edema, so as to adjust the daily drinking water in time.

in short

For patients with kidney disease, drinking more and drinking less is not entirely correct. Reasonable drinking water according to edema and daily urine volume is the correct way to drink water.

Hello, for kidney friends, how to drink water is very particular. Replenishing water not only refers to drinking water, but also includes water in fruits, vegetables, porridge and other foods. The amount of drinking water should be increased or decreased according to the eating situation.

1, early chronic kidney disease should drink more water, and patients with early chronic kidney disease should drink more water to accelerate metabolism and help detoxify. When you feel thirsty, your body is already in a state of water shortage. Long-term water shortage will damage the kidneys. How much water is appropriate to drink? China Nutrition Society recommends drinking at least 1500ml of water every day. But you don't have to drink 8 glasses of water. If you eat more fruits and liquid food that day, you can appropriately reduce the amount of water you drink. If you have diarrhea, fever, sweating, etc. You should also increase the amount of water according to the severity of the situation. Principle of drinking water for patients with chronic kidney disease: measure it out, a small amount for many times.

2, kidney friends should limit drinking water when oliguria and edema. The total amount of liquid should be kept at: urine volume of the previous day +500ml. When there is severe edema or oliguria, the water you drink can't be excreted normally, and it will accumulate in the body, which will increase the burden on the heart and kidneys. In severe cases, heart failure will occur, so you should limit the amount of water you drink. At the same time, it is necessary to determine the amount of drinking water according to the individual's illness, physical condition and activity, and avoid drinking too much or too little. Replenish water quickly when thirsty, and long-term water shortage is harmful to the kidneys; Don't drink more water when you are not thirsty, so as not to increase the burden on your kidneys.

3, anuria, dialysis kidney friends should drink water without urine according to weight changes, or enter dialysis kidney friends, you need to judge and adjust the amount of water according to your own weight changes. The way to measure weight is to choose a fixed time point every day, such as after getting up, before eating, or before going to bed. Daily weight gain should not exceed 0.5% of body weight, and weight gain during two dialysis sessions.
