How much water should patients with kidney disease drink, and can kidney disease drink more water?

First, the drinking method and drinking water varieties are particular.

Although there are many types of drinking water on the market, it is still recommended that friends with kidney disease drink plain water, not mineral water and various beverages. At the same time, remember not to overdrink; Don't wait until you're thirsty to drink a lot of water, you should follow the principle of drinking a small amount and drinking it multiple times, and you can drink it in small sips to moisturize.

2. Learn to self-monitor, measure in and out, and achieve reasonable and scientific drinking water.

1.When discussing how to control water intake, people with kidney disease can roughly calculate their amount of water and adjust their water intake.

For patients with kidney disease who do not have significant edema, excessive restriction of water intake is not necessary. The general water intake is equal to the total urine output of the previous day (i.e., the urine output in 24 hours); Add another 400 to 500 ml. For example, if the urine output is 1500 ml in the previous 24 hours, you should drink 1900 to 2000 ml of water.

2.Make it a habit to weigh yourself regularly.

Wake up at the same time every morning, defecate and defecate, fast, wear the same clothes and shoes, measure weight, if there is no significant change in weight, indicating that the water intake is more successful.

3.Always observe whether your ** and lip mucous membranes are dry, whether there is puffiness in the eyelids or lower limbs, as well as changes in urine color and blood pressure.

3. When there is obvious edema, water intake should be restricted.

In acute nephritis, nephrotic syndrome, diabetic nephropathy, chronic renal failure and other kidney diseases, water intake should be restricted when there is significant edema. Of course, you should also be hospitalized at this time, and you should follow the advice of a nephrologist.

4. Patients with renal failure and oliguria should not blindly drink water or restrict water.

For patients with renal failure and oliguria, water intake should be adjusted according to body weight, blood pressure, and water output; Don't drink water blindly or limit water. For example, blind water restriction may cause the body to lack water, leading to renal hypoperfusion and accelerating the further deterioration of already damaged kidney function.

If the kidney drainage function is normal, you can drink 1000-2000 ml of water every day, which is basically in line with the normal metabolic needs of the human body.

If the kidneys are impaired in drainage, it is usually necessary to "live within their means", which means that the amount of water you drink is based on the amount of urine you need each day to prevent worsening of the edema.

Drinking plenty of water has great benefits for renal excretion. Drinking more water is not a big gulp of water at once. Drink slowly and in small amounts, taking two or three sips at a time. This is the scientific method of science.

If you have chronic nephritis, you should drink plenty of water, which is very beneficial to the condition, but be careful not to eat cold food. Bed rest, combined with ** nephritis medications. Reduce urine protein, thereby protecting the kidneys, in order to get sooner**.

It is recommended to control the amount of water intake appropriately to avoid excessive water intake that can lead to aggravated edema. At the same time, medication should be taken regularly under the guidance of a medical professional.

There are many types of kidney disease, but what kind of kidney disease are you? Some people with kidney disease drink more water, which has certain benefits for the kidneys, and some drink it appropriately, and do specific ** for specific problems.

Should you drink more or less water for nephritis?

Conclusion: If you have yellow urine, dry mouth, and sweating a lot, drink more; Edema, frequent urination, easy drooling can be reduced.

If you are thirsty and do not want to drink, you should still regulate your physique and restore the warming function of kidney yang. It is prudent to use traditional Chinese medicine that Wenyang's aconite, cinnamon, and dried ginger are not friendly to nephritis, and improper compatibility often aggravates the condition.

Patients with kidney disease should drink about two liters of water every day. Don't drink too much and don't drink too little. If you drink too much, it will increase the burden on the kidneys, and it is not good for kidney function.

If you don't drink water, the toxins in the body can't be excreted, and the condition will be aggravated, so it is recommended to drink as much water as possible.

No, don't listen to Western medical nonsense. It's too late to have a time for everything.

As we all know, human beings can never survive without water, and all the animals and plants in the world cannot live without water, and 70% of our human bodies are made up of water. Moreover, adults generally have a daily water intake of 2000 ml in order to excrete toxins from the body, but this does not mean that drinking more water is good, and there are many problems for nephritis patients to pay attention to when drinking water. Healthy adults drink plenty of water to help their health, but they should also pay attention to their intake, usually 2,000 milliliters a day is enough, and a lot of this water comes from food.

For nephritis patients, they can't drink too much water, and the kidney function of nephritis patients will be weaker than that of normal healthy people, which means that their metabolic ability is also poor, and drinking too much water will put a lot of pressure on the kidneys. So, how do people with kidney disease drink water?

How to drink water in patients with kidney disease should be judged according to the general condition of the patient with kidney disease. Depending on the type of kidney disease, the state of kidney function and the state of heart function, the amount of water consumed is also different.

1. For patients with urinary tract infection, small urinary tract stones, hyperuricemia, after taking sulfonamides, mild to moderate renal insufficiency combined with azotemia and no edema, drink more water appropriately and keep the daily urine output at about 2500ml to promote the excretion of urinary tract bacteria, small stones, uric acid crystals, drug crystals, and nitrogen-containing substances, and maintain kidney function at a stable level.

2. For patients with ordinary hematuria, proteinuria, and normal renal function, they should be treated as normal. The daily water intake is about 2000ml, and the urine output is about 1800ml.

3. For patients with nephrotic syndrome with massive proteinuria, lower limb or even systemic edema, ascites, and pleural effusion (including minimal lesions, membranous nephropathy, focal segmental glomerulosclerosis, diabetic nephropathy, renal amyloidosis, etc.), try to eat less salt and drink less water appropriately. Diuretics are needed to reduce swelling if necessary. Make sure you drink less water than you excrete, and you should lose about your weight every day until your swelling has subsided.

4. For patients in the oliguric stage of acute renal failure, decreased urine output in the late stage of chronic renal failure, dialysis without urine, as well as patients with cirrhosis with a large amount of ascites, congestive heart failure, breath-holding and patients who cannot lie flat at night, the intake of salt and water should be strictly restricted in accordance with the principle of "living within the amount of what is in the amount". Patients with poor diuretic effect should be treated with blood purification dialysis in time and actively develop the primary disease.

Water is important for both the human body and the kidneys, drinking less water will affect the excretion of metabolic wastes, and dehydration will aggravate kidney damage. However, if there are conditions such as edema and heart failure, drinking more water is not good for health. Only by drinking a moderate amount of water every day and maintaining a normal urine output will it have a positive effect on kidney health.

1.If you have less urine, drink less water.

For example, patients with nephrotic syndrome who have difficulty draining, then we need to calculate the amount of water to drink, drink less water, and at the same time promote drainage, water dilution and swelling. Especially for uremia patients, it is important to strictly control water.

How much water do you drink? Water intake on the day = urine output of the previous day + 500ml.

Note that the amount of water you drink includes not only the water you drink, but also the water in various watery foods such as porridge and soup.

2.If you need to urinate more, drink plenty of water.

If there are kidney stones, then you need to drink more water and urinate more, which is conducive to flushing out the stones; If you have high uric acid, you also need to drink plenty of water, which is conducive to the excretion of uric acid.

For patients with kidney stones and high uric acid, it is recommended to drink 2500-3000ml of water per day and at least seven or eight glasses of water per day.

3.In general, patients are free to drink water.

For patients with average condition, there is no obvious edema, no hypoproteinemia, no stones and high uric acid, and kidney function is okay, so it doesn't matter how much water you drink. The kidneys have the function of maintaining water balance: whether you drink more or less, the kidneys will "intelligently" regulate how much or less water you produce.

In addition, in addition to urine, sweat is also important in some cases

If you sweat a lot in the summer, you can drink more, and if you sweat less in the winter, you can drink less. When you have a cold, exercise, and sweat a lot, drink plenty of water.

In short, the amount of water that patients with kidney disease drink is determined by the amount of water excreted, and maintaining water balance is the best.

People often say that they drink more water when they are sick, but some patients with kidney disease are already swollen and are still desperately drinking water, which is of course not true. In fact, water should maintain a state of dynamic equilibrium in the human body, and there is a relationship between how much water to drink and how much water to discharge.

For example, a patient with nephrotic syndrome has generalized edema due to hypoproteinemia, and what to do at this time is to drain the pre-existing water in the body as much as possible, and to control the amount of water drunk into the body, and slowly eliminate the patient's edema.

For other types of patients, such as kidney stones, then we should encourage them to drink more water appropriately, and drink more skin and drainage, which is conducive to the discharge of stones.

For some patients with kidney disease who do not have hypoproteinemia or stones and have good kidney function, it is recommended to decide according to the degree of thirst, the amount of sweating and urination, and basically maintain balance. For example, if you sweat a lot in summer, you drink more water, and if you sweat less in winter, you drink less water.

Therefore, whether we drink more or less water is determined by how much water we excrete, and it is good to maintain a dynamic balance.

The importance of water in maintaining the vital activities of the human body is self-evident, and it is called the "source of life". Drinking water helps the body to remove waste products from metabolism and reduce the concentration of toxic substances in the kidneys, thereby reducing kidney damage.

Normal people's daily water intake is 1500ml 2000ml, one of the main functions of the kidneys is drainage, drinking water for patients with kidney disease is very important in daily dietary care, drinking too much or too little water may aggravate the condition, increase the effect and difficulty of **, so for normal people, drinking water is not a problem, but for patients with kidney disease, it has become a big problem. Drinking too much or too little water is not conducive to the control of kidney disease, and it is necessary to learn to drink water normally.

How should people with kidney disease drink water?

1. Patients with chronic kidney disease.

For example, some patients with renal insufficiency, if the body does not have symptoms of edema, you can drink more water in moderation, which can increase the amount of urine, so as to excrete metabolic waste and toxins from the body.

2. Patients with kidney disease with edema.

Not all kidney diseases require more water, and those with one of the conditions of "edema", "oliguria" and "massive proteinuria" need to limit their water intake.

For example, in patients with kidney disease and edema, weight and urine output should be monitored daily. And record the urine output for 24 hours, as well as the total amount of water, soup porridge, milk, food and other liquids, so that the intake is kept at: urine output +500ml.

The extra 500ml is to meet the insensible water loss such as respiration and ** to maintain the "balance of the water".

Small details of life can help people control their water intake. For example, water intake includes drinking soup and porridge, so drink less; Fruits contain a lot of water, so eat less fruits when they are rotten and edema; Eat less salt, too much salt will cause an unquenchable thirst and cannot reduce the amount of water you drink; Quantify a glass of water every day, take medicine and drink only one glass, no longer supplement, and try to drink water in small sips, so as to facilitate the control of water intake.

3. Chronic kidney disease combined with heart failure.

For patients with chronic renal failure, the amount of urine produced has been significantly reduced, and such people must control the amount of water they drink, and take the principle of drinking a small amount of water when they are asleep, and not drink a large amount of water at one time.

4. Patients with urinary tract infection.

For patients with urinary tract infections, it is essential to develop a good habit of drinking plenty of water, which can flush the urethra and prevent the bacteria from multiplying. For patients with urinary tract stones, they should also drink plenty of water, which is conducive to the elimination of stones from the body. As long as the daily water volume can reach 2500 ml, it can speed up the excretion of urine, and can deposit some calcium and impurities in the kidneys and excrete them, which is conducive to the health of the body.

It is important to remind everyone here that the water referred to here is not a drink, but pure water.

Never replace water with a drink, the phosphate and sugar in the drink can promote the precipitation of calcium, and when the calcium content in the urine increases, kidney stones can form. Carbonated drinks contain certain substances that can raise blood pressure and damage the kidneys, so drinks should not be used instead of plain water. For healthy people, remembering to drink water every day can prevent the appearance of kidney disease, which is also beneficial to the body's health.

Dr. Fu Wenjing, Chief Physician of the Department of Nephrology, Xuanwu Hospital, Capital Medical University, Jia Linpei.

Doctor, I have chronic kidney disease, so I can't drink more water in the future? "Doctor, if I drink more water every day, my creatinine can go down, right?" "In the nephrology ward, we often hear the question, why is it that even drinking water has become a problem after suffering from chronic kidney disease?

Chronic kidney disease, as the name suggests, is long-term chronic damage to kidney function. The disease causes the kidneys to excrete less metabolic waste products and water, which can lead to symptoms such as decreased urine output and edema. Some patients believe that since the kidneys have decreased their drainage function, the less water they drink, the more water they retain, the less water they retain, so they blindly limit their daily water intake; Some patients also believe that since "garbage" such as creatinine and urea are excreted through urine, only by drinking more water and urinating can creatinine be lowered and the kidneys protected.

Both of these ideas are wrong.

A clinical study of 631 patients with chronic kidney disease, published in the Journal of the American Medical Association, showed that patients who increased their water intake by 1000 to 1500 milliliters per day or decreased by 250 500 milliliters of water intake did not have significant changes in kidney function after one year of follow-up. This shows that patients with chronic kidney disease do not drink any different water intake from normal people in the absence of special contraindications. Normal people need to excrete 1800 2200 ml of urine every day to ensure that the body's metabolic waste is effectively removed, to remove the water contained in three meals and the water lost in daily activities and respiration and body surface, we need to drink 1500 2000 ml of water every day, generally no more than 3000 ml.

Adequate water intake can reduce arginine vasopressin, thereby lowering blood pressure, improving the pressure difference between the inner and outer arterioles, reducing the burden on the kidneys, and promoting urine production.

Patients on long-term hemodialysis or non-maintenance dialysis patients with oliguria (urine output < 400 ml per day), anuria (urine output < 100 ml per day), chronic heart failure, massive proteinuria (urine protein per day), hypoproteinemia, and limb edema need to limit their daily water intake. These patients have water retention, and if they do not control their daily water intake, excessive water accumulation in the body can increase blood pressure, increase the workload of the heart, and increase the risk of malignant diseases such as acute heart failure or stroke.

Therefore, for non-dialysis patients with chronic kidney disease who have water retention, daily urine output needs to be recorded, and the daily water intake should be controlled within "urine output-food water content + 500 ml". Dry body weight refers to the ideal body weight of the patient with no excess water retention and no lack of water, which is the weight when the patient gets off the plane after hemodialysis, and the patient feels comfortable at this time. For long-term hemodialysis patients, water intake should be calculated based on body weight, and the weight gain between dialysis sessions should not exceed 5% of the dry body weight. ▲
