Dietotherapy Plays an Important Role in Slowing down Renal Failure Caused by PKD

Polycystic Kidney Disease (PKD) is a genetic disease and can accompany patients’ whole life. If the patients do not receive effective treatment in an early time, all of them will end with Renal Failure. In order to slow down Renal Failure, dietotherapy plays an important role on this point. Moreover, dietotherapy can alleviate the complications of Renal Failure.

Dietotherapy for patients with Renal Failure before dialysis

(1) Protein intake

At the first and second stages of Renal Failure, the patients should reduce their protein intake to 0.8 grams/kg per day. After their disease develops into the third stage of Renal Failure, they should keep a low-protein diet and keep their protein intake within 0.6 grams/kg per day. In their total protein intake, haft of the protein should be obtained from quality protein such as lean meat, fish, and egg white and so on.

(2) Calorie intake

When patients keep a low protein diet, they should have enough calorie intakes so as to guarantee enough nutrition. They should have 125~146 calories/kg per day.

(3) Other nutrition

The patients should be supplied with various kinds of vitamins and folic acid. However, when patients have hyperphosphatemia , they should keep the phosphorus intake below 800 milligrams per day.

However, the patient with Renal Failure should make their diet schedule under their doctors’ guidance. Some patients think that protein can accelerate the kidney damage so they limit their protein intake blindly. As a result, it causes severe malnutrition to them so the patients are very likely to have fatigue, anemia and so on. Therefore, for patients with Renal Failure, if they keep a low-protein diet, they should have follow-up regally and adjust their dietary schedule based on their disease condition.

The doctors should help patients with Renal Failure make a scientific diet schedule according to different patients’ kidney condition, pathogenesis ( such as Diabetic Nephropathy, Hypertensive Nephropathy, Chronic Nephritis and so on), nutrition condition, absorption and digestion and so on).


Scientific dietotherapy is important for patients with Renal Failure to slow down their kidney damage, Therefore, they should make a proper dietary schedule under their doctors’ guidance.
