How to Alleviate Swollen Leg or Foot for PKD PatientsIt is unavoidable that some symptoms and discomforts appear, as the progression of Polycystic Kidney Disease. Swollen leg or foot, one of these symptoms, is uncommon but indeed affects some patients’ normal ability to work. Today, kidney experts at pkd clinic are here to talk about how to alleviate swollen leg or foot for PKD patients.

Swollen leg or foot and Polycystic Kidney Disease

In PKD, cysts can develop in any part of kidneys. Renal cortex, one important part of kidney, contains more than one million of nephrons, which include glomeruli and renal tubules. As cysts in renal cortex grow, more and more glomeruli and renal tubules will be damaged. As a result, swelling occurs easily.

Generally, swollen leg or foot is due to two conditions. One condition is that glomerular filtration function declines but renal tubules can still reabsorb water and sodium normally. This can cause fluid and sodium retention. In the other condition, PKD patients have severe proteinuria. A heavy loss of protein in urine leads to low plasma protein level, resulting in swelling.

How to alleviate swollen leg or foot for PKD patients?

To ease patients’ swelling, we give some relative suggestions based on the causes.

1. Control the fluid and sodium intake: If your swelling is due to fluid and sodium retention, try to adjust the amount of water and sodium that you take one daily.

2. Consume high-quality protein: This can reduce the burden on damaged kidneys, because high-protein foods produce fewer waste products. For PKD patients, plant protein is worth a try. (If you don’t know which foods contain plant protein, leave a message or send email to

3. Drink some herb tea: It is proven that corn stigma, lalang grass rhizome and dandelion root can not only increase the output of kidneys but also slow down the progression of PKD. Therefore, you can drink one cup of herb tea with the doctor’s guidance.

4. Shrink kidney cysts: Some herbal medicines such as ground beeltle and rhizoma sparganii have an outstanding effect on draining PKD cysts in different parts. Only if these cysts keep in small size, they can’t damage the glomeruli and renal tubules any more. Consult the doctor to ask which herbal medicines are good for you.
