A RENAL DIET
The dietary recommendations for Acute Kidney Injury (AKI), Chronic Kidney
Disease (CKD), and Hemodialysis (HD) differ based on the stage of kidney
impairment and the need to manage fluid and electrolyte imbalances. Here’s an
overview of the key differences in these diets:
1. Acute Kidney Injury (AKI) Diet
Goal: Preserve kidney function, promote healing, and prevent complications
such as hyperkalemia, hyperphosphatemia, and fluid overload.
• Protein:
o Early stages of AKI may require a moderate to low-protein intake
to prevent excess nitrogen waste build-up. As kidney function
improves, protein intake may be increased.
o 0.6-0.8 g/kg/day is recommended in early stages but may
increase as kidney function recovers.
• Sodium:
o Restricted sodium intake to prevent fluid retention and
hypertension. Recommended intake is usually 1,000-2,000
mg/day.
• Potassium:
o Limit potassium to prevent hyperkalemia. Intake is typically
around 2,000-3,000 mg/day, depending on lab values.
• Phosphorus:
o May need to be restricted to prevent hyperphosphatemia, especially
if levels rise. Intake should be 800-1,000 mg/day.
• Fluids:
o Fluid intake may need to be restricted to match output, especially
if the patient is oliguric (low urine output).
2. Chronic Kidney Disease (CKD) Diet (Stages 1-4)
Goal: Slow disease progression, control blood pressure, and prevent
complications like electrolyte imbalances.
• Protein:
o A low-protein diet helps reduce the buildup of urea and other
waste products.
o 0.6-0.8 g/kg/day is typically recommended in non-dialysis CKD
(Stages 3-4).
• Sodium:
