What is the typical protein intake recommended for an adult PD patient?

• A. Approximately 1.0–1.5 g/kg/day, adjusted for nutritional status and catabolic rate
• B. 0.5 g/kg/day
• C. 2.5 g/kg/day
• D. No protein required

Answer: (A)

Protein needs rise in peritoneal dialysis because amino acids are lost in the dialysis fluid and the body is in a more catabolic state. To offset these losses and maintain nutritional status, adults on PD are typically advised to consume about 1.0–1.5 g of protein per kilogram of body weight each day, with the exact amount adjusted for overall nutritional status and how catabolic the patient is. This range helps replace what’s lost in the dialysate while supporting lean body mass and serum proteins like albumin. For a typical patient, that might be around 70–105 g of protein daily for a 70 kg individual, but the target is personalized. The other options don’t fit because 0.5 g/kg/day is too low to compensate for PD-related losses, 2.5 g/kg/day is excessive for most adults, and no protein is not appropriate for someone undergoing PD.
