Should You Drink More Water or Less Water with Kidney Disease

Should You Drink More Water or Less Water with Kidney DiseaseShould you drink more water or less water with kidney disease? Someone may think that excessive water intake can worsen swelling and put extra stress on kidneys, while some may think that drinking water can help discharge toxins from the blood and reduce their accumulation in body. Which opinion is right? Go on reading to learn more information.

Water is an indispensable part of the human body. Usually people are advised to drink more water, mainly to promote body metabolism. However, due to the impairment of renal function and the decline of various functions, especially the function of filtration and metabolism, the kidney patients can not drink water at will, and there are clear limitations in time and quantity.

There are four conditions. You can check whether you should drink less or more water.

When GFR is higher than 60 ml/min, and kidney function is normal, you can drink more water.

In patients with stage 1 or 2 of Chronic Kidney Disease (CKD), the renal function has not been substantially impaired, or the impairment is mild, and the glomerular filtration rate (GFR) is generally above 60 m/min. Kidney patients who meet these conditions need not drink too restrictively. As usual, they should take at least 2000 ml of water every day. Attention should be paid to maintaining a balanced drinking throughout the day rather than waiting until you are very thirsty. Thirst indicates that the human body is in urgent need of water at this time. The kidney dehydration will lead to increased metabolic burden and less urine production, which is not conducive to the metabolism of toxins, thus is not conducive to the stability of renal function.

Adequate intake of water to maintain adequate blood flow in the kidney is conducive to the recovery of renal function.

For patients with severe edema, water restriction is necessary.

The kidney has the function of regulating the balance of water and electrolyte. When the kidney function is damaged, these functions decrease, leading to water retention in the body and causing edema. In addition, the leakage of a large number of protein will also aggravate the retention of sodium and water in the body, aggravating the situation of edema. Kidney patients are often accompanied by edema of lower limbs, ankles, eyelids and faces, and even severe systemic edema.

The daily intake of water in patients with mild edema is generally 1000 ml, while that in patients with severe edema is less than 1000 ml. Usually the daily intake is the urine volume the day before plus 500ml. If you urinate 400 ml the day before, it is advisable to control the next day's intake at about 900 ml.

In addition, it should be noted that patients with edema have abnormal sodium metabolism, so not only water but also salt should be limited. Generally, daily salt intake is less than 3g. Salt intake can be adjusted according to the condition of edema.

For patients with oliguria or anuria, water intake should be appropriate.

With the occurrence of fibrosis and sclerosis of the kidney, the kidneys become atrophic, glomerular filtration and renal tubular reabsorption function gradually decrease, and urine output decreases. For oliguria and anuria patients, there is no strict requirement on water intake. However, if accompanied by edema and proteinuria, water intake should be limited.

In some patients, oliguria is caused by acute progress of the kidney, which leads to acute renal failure due to accumulation of toxins. In order to expel toxins as soon as possible, these patients need to drink a lot of water without restriction.

Dialysis patients drink water according to weight change.

Dialysis patients usually do not need to limit water intake, but in the pre-dialysis and post-dialysis period, water still needs to be controlled. Hemodialysis can help discharge excess water and toxins in the body. Therefore, in order to avoid destroying the concentration of dialysate, it is necessary to control the intake. Generally, the proportion of water intake is determined according to body weight, so dialysis patients should maintain their weight as healthy and stable as possible, and gain less than 3% during the two dialysis sessions.

Water intake is arranged according to dialysis times as follows:

Patients who have dialysis three times a week drink 500 ml of water plus urine the day before.

The patients who have dialysis twice a week drink 300 ml of water plus urine the day before.

Patients who have dialysis once a week drink 100 ml of water plus urine the day before.

In addition, kidney patients should pay attention to two points. One is drinking high-quality water. Daily drinking water can choose mineral water, or boiled water, but must not be replaced by beverages; the other one is to limit water and salt at the same time.
