Nutrition and Peritoneal Dialysis

Since peritoneal dialysis is done every day, there are usually fewer food and fluid restrictions compared to haemodialysis.

The goals of the diet for peritoneal dialysis patients are to feel well, have a good appetite, normal blood pressure, and acceptable lab results. This can be achieved by:

  • Following a diet as prescribed by a doctor/dietician
  • Completing all dialysis exchanges
  • Taking medicines properly

One main change compared to earlier stages of chronic kidney disease is the higher need for protein. As your body loses peptides (components of proteins) through the dialysis treatment, you should eat more protein now. Additionally to protein losses there are other factors that may promote protein-energy-malnutrition. For example, many patients have less appetite due to high concentrations of glucose in their blood (resulting from glucose absorption from the dialysis fluid) and the symptoms of chronic kidney disease. Thus, it is important that you take in sufficient amounts of proteins and other nutrients!1,2

A restriction of your fluid intake is usually not necessary. But sometimes it may be necessary to reduce the intake of fluids and/or salt to correct fluid overload and high blood pressure.1,2

Furthermore, the special diet for peritoneal dialysis must contain the right amount of vitamins and minerals.1,2

In dialysis stage it is good for you to eat protein-rich foods, e.g. meat.

How to implement nutritional management in every-day life

As you have to pay attention to several ingredients when adjusting your nutrition to your individual needs, it is advisable that you get information from a specialised dietician. Please ask your doctor about your individual nutrition requirements and if instructions from a dietician might be necessary.

To support you in planning your cooking, we provide a Food Ingredient Calculator (a database where you can check, which amounts of different ingredients your meal contains).

Treatment options

Treatment of chronic kidney disease (CKD) varies according to the severity. However, steps can be taken in all cases to: control hypertension, correct salt and water imbalance, treat urinary tract infections, and reduce risk of heart and blood vessel diseases. Most people with CKD will be able to slow down progression through regular check-ups and medication intake.

Nutritional management

When you suffer from chronic kidney disease (CKD), nutritional management is an essential part of your treatment plan. Depending on the severity of your disease, your recommended diet may change over time. In predialysis, a low protein diet is a key pillar of a CKD therapy.
