In CKD, what dietary modifications are commonly recommended to manage complications?

• A. No dietary changes
• B. High protein and unrestricted potassium
• C. Low phosphorus and sodium restrictions only
• D. Protein restriction, sodium restriction, potassium restriction if hyperkalemic, phosphorus restriction, and fluid management

Answer: (D)

In CKD, the goal is to lessen the load on the damaged kidneys while keeping nutrition safe and the body's fluid and electrolyte balance stable. Restricting protein helps cut the amount of waste the kidneys have to filter, reducing uremic symptoms and helping protect remaining kidney function, while still aiming to prevent malnutrition. Limiting sodium helps control blood pressure and fluid retention, which are common problems as kidney function declines. Potassium restriction is added if potassium levels are high, because elevated potassium can cause dangerous heart rhythms. Phosphorus restriction is important because the kidneys can’t excrete phosphorus well in CKD, leading to bone and cardiovascular issues; many patients also take phosphate binders with meals. Fluid management is essential to prevent overload, which can cause edema and hypertension, and guidelines for fluids often depend on urine output and dialysis status. Together, these dietary adjustments address the main CKD complications, making the comprehensive approach the best choice.
