Kidney Dialysis: What Can and Can't to Eat

Kidney dialysis is a life-support treatment that uses a special machine to filter harmful wastes, salt, and excess fluid from your blood. That restores the blood to a normal, healthy balance. Dialysis replaces many of the kidneys important functions.

Kidney dialysis is a necessary treatment for people with end-stage kidney disease or permanent kidney failure. You need dialysis if you've lost about 85% to 90% of your kidney function. Temporary dialysis may be needed in some cases.

Hemodialysis is most commonly used to treat people with end-stage kidney disease. However, children who need dialysis often receive peritoneal dialysis.

The kidney dialysis treatment itself usually does not cause any pain or discomfort. However, some patients may develop low blood pressure, which can lead to headache, cramping, nausea, and vomiting. This usually goes away after a few treatments.

What can I eat?

In addition to enjoying a variety of nutritious foods, the hemodialysis diet will introduce a higher amount of high-quality protein into your eating plan. Your dietitian will determine the amount. High-protein foods such as lean meat, poultry, fish and egg whites provide all the essential amino acids your body needs.

What can’t I eat?

Foods containing high amounts of sodium, phosphorus and potassium are restricted. Your dietitian will provide you with food lists that indicate which foods are allowed and which ones you should avoid or limit. You will also limit your fluid intake.
