Do I need a special diet during kidney dialysis?

Generally speaking, people on dialysis are advised to increase the protein they eat, and limit the potassium, phosphorus, sodium and fluid in their diet. People with diabetes or other health conditions may have additional diet restrictions. It's important to talk with your dietitian about your individual diet needs.

Your dialysis care team will monitor your treatment with monthly lab tests to make sure you get the right amount of dialysis and that you are meeting your dietary goals.
