Some patients with nephropathy, daily urine volume is normal and no obvious symptoms, worry about drinking water will appear edema, blindly limit drinking water; but some edema in patients with nephropathy that drink can help the kidneys to remove body toxins, desperately drink water, resulting in systemic edema and even the emergence of heart failure. Experts said these two behaviors are wrong.
For patients with kidney disease whether can drink more water, can not simply assess whether to drink or drink good, according to the body "thirst" signal to appropriate drinking water. If you feel thirsty should quickly replenish water, if water shortage for a long time on the kidney is not good, if not thirsty do not drink water, it will not increase the burden on the kidneys, if not thirsty and drink extra water to kidney function out of itself more weak kidney burden. It's also bad for kidney recovery. Therefore, kidney disease patients do not care too much about drinking water problems, as long as the principle of moderate moderation can be.
The best time to drink water is: after getting up in the morning, around 10 a.m., around 3 p.m., before bedtime. Drinking water before meals and after meals should be 15 minutes before meals, and the interval between meals should be longer. The longer the food is, the longer the digestion time is, the 30 minutes after eating fruits, and 3 hours after eating meat.
The other is the calculation method of "living within one's income". We should first make clear the "dominant water loss" and "non dominant loss" and "water" meaning. Dominant water loss refers to the loss of urine, feces, vomit, gastrointestinal tract and drainage of the water; non dominant water loss in skin, respiratory tract from the water; in unboiled water refers to the release of food water oxidation and cell The new supersedes the old. Usually the dominant water loss can be easily calculated; 0.5 ml / kg body weight / hour to calculate non dominant water loss, of course, according to age, body temperature, air temperature and humidity adjusting; calculating the endogenous content from 400 to 500 ml of urine, plus 1 days before the calculation of the discharge amount of drainage. For patients with kidney disease without severe edema, the amount of water can be calculated according to the above calculation method.
"Reasonable drinking water is very important for patients with kidney disease, as long as the reasonable drinking water, the condition will be stable control."." In acute nephritis, nephrotic syndrome, acute renal failure in oliguria or anuria stage, chronic renal failure oliguria and did not enter the renal replacement therapy with obvious edema, should limit the intake of water; if there is no edema, no restriction of drinking water; for hemodialysis patients, urine volume has significantly less than normal people that should be appropriate to limit the amount of drinking water, drinking water to two times to control the amount of interdialysis weight gain does not exceed the standard weight of 5%.
