The diet is designed so as to maintain a balance of electrolytes, minerals, and fluid in patients on dialysis.
Most dialysis patients urinate very little or not at all, and therefore fluid restriction between treatments is very important. Without urination, fluid will accumulate in the body and cause excess fluid in the heart, lungs, and ankles.
Patients on dialysis need a high protein intake to maintain adequate nutrition. Patients on dialysis can become malnourished and this often means a poor outcome.
The diet will help dialysis patients feel as good as possible.
