CKD & dialysis nutrition

Key areas to discuss with your renal team

• Sodium: reducing excess salt may help manage blood pressure and fluid retention. Flavour food with herbs, lemon, spices and aromatics as suitable.
• Protein: requirements differ before dialysis and during dialysis. Do not independently start a high-protein diet.
• Potassium: some people need potassium limits; others do not. Base choices on blood results and professional advice, not blanket food lists.
• Phosphorus: packaged foods with phosphate additives and some dairy/processed meats can be relevant. Medicines called binders must be taken exactly as prescribed.
• Fluid: a prescribed allowance may include water, tea, soup, ice and other liquids. Individual guidance is essential.
• Diabetes and heart health: these often need to be planned alongside kidney nutrition.

For dialysis days

Eating, protein needs, fluid and symptom management should be planned with the dialysis unit and renal dietitian. Report nausea, poor appetite, cramps, swelling or rapid weight changes promptly.
