Nutrition: Pre-Dialysis Diet Download PDF, 751 KB, PDF Understanding Diet and Kidney DiseaseOur kidneys help to:Remove waste productsKeep levels of electrolytes stableRemove excess fluids and regulate blood pressureWhen your kidneys are not working properly, waste products can build up in your body. This can cause loss of appetite, nausea/vomiting, fatigue and weakness. Waste products are formed when protein is broken down and used. Excessive protein intake causes your kidneys to work harder. When your kidneys are not working properly, potassium and phosphate may build up in your blood, which can have negative effects on your body: High blood potassium levels can cause irregular heart rhythm, which can cause your heart to stop beating.High blood phosphate levels can draw calcium out of your bones, making them weak and brittle. This can also result in calcium deposits in your blood vessels, lungs, eyes and heart.As your kidney disease progresses, extra sodium and fluids may build up. This can cause swelling, difficulty breathing and increased blood pressure. Goals of Dietary Management√ To preserve existing kidney function and delay the progression of kidney disease, which will ultimately require dialysis or transplant.Basic Dietary GuidelinesProteinIt is important to have enough protein to build and repair tissues in the body.Everyone has different protein needs.
