A Healthy Diet Plays an Important Role in Slowing down PKD Development

Polycystic Kidney Disease (PKD) is a common genetic disease. However, there is no effective treatment for the disease. Therefore, effective prevention of PKD development is extremely important for all patients. A healthy diet plays an important role slowing the disease development.

1. Keep a low potassium

As the cysts enlarge, they will oppress the renal tissues thus causing kidney damage. Therefore, the kidney can not discharge the potassium in their body normally thus causing it to accumulate in their body. If the patients have too high potassium intake, it will cause hyperkalemia, which can cause arrhythmia and even death.

2. Limit salt intake properly

If the patients with PKD have high salt intake, it will cause their blood pressure to increase. After the patients have too high salt intake, it will cause the retention of sodium and water in body. It can cause their vascular smooth muscle to swell, blood vessel wall to become thin. As a result, the obstruction of blood vessels will increase. At the same time, with the sodium content increase in blood, it can cause the blood volume to increase, which can aggravate the burden to kidney and heart. Therefore, the patients’ blood pressure will increase. Moreover, if the patients have retention of water and sodium, it will cause or aggravate the original edema. Therefore, it is very necessary to limit their salt intake when patients have serious Hypertension or edema.

3. Limit phosphorus intake

Phosphorus is mainly discharged by kidney. For patients with Renal Failure, they can not discharge the phosphorus in their body. Therefore, it the patients have too high phosphorus intake, they are very likely to have hyperphosphoremia.

4. Avoid high fat intake

If the patients have too high fat intake, it is very likely to cause hyperlipemia. It can damage the endothelial cells of kidney thus causing the permeability of blood vessels to increase. As a result, plasma lipoprotein can enter blood vessels and deposit on the blood vessels inner membrance thus causing arteriosclerosis.

5. Keep high vitamin intake

Vitamin plays an important role in energy metabolism. If the patients can not get enough vitamins, it will cause serious energy disorder. As PKD patients’ renal functions decline, the patients often have vitamin metabolic disorder. Therefore, the patients should keep enough vitamin intakes timely.

However, some patients on dialysis may lose mass protein and potassium in their dialysis process. Therefore, this part of patients should increase these substance intakes properly instead of limiting their intakes.


A healthy diet can prevent PKD development effectively and decline kidney damage to patients. Therefore, the patients should pay more attention to what they eat in their daily life and supply their nutrition intake properly according to their own disease condition.
