Peritoneal Dialysis Explained: 10 Things Need to Know About This Kidney Treatment

6. Dietary Freedoms and Sodium Savvy

One of the less obvious but significant advantages of peritoneal dialysis is the increased dietary flexibility compared to hemodialysis. Because PD is performed more frequently, waste products and fluids are cleared more continuously, mimicking natural kidney function more closely. This often means less stringent restrictions on fluids, potassium, and phosphorus, allowing patients a broader range of food choices. However, patients still need to be "sodium savvy," as the dialysis solution contains dextrose (a sugar) that can contribute to fluid retention if too much sodium is consumed. A focus on balanced, low-sodium meals remains crucial for optimal fluid management.
