| [ Summary ] | Protein and energy malnutrition are common in dialysis patients. Signs of malnutrition are strongly associated with increased morbidity and mortality. Obesity is not a feature of dialysis patients but is observed. In CAPD, a significant increase in body weight, derived from peritoneal glucose absorption was observed, mainly due to a rise in fat mass. In subjects on chronic dialysis, the lipid profile is characterized by hypertriglyceridemia accompanied by reduced high-density lipoprotein (HDL) cholesterol. Obesity is a more potent factor than renal failure as a cause of deteriorating lipid profiles. The requirements for protein are increased in both HD and CAPD patients, whereas energy requirements are not different from those of healthy subjects. Recommended energy intake for dialysis patients is 35kcal/kg/day. However, energy requirements depend on the level of physical activity. Higher intake is necessary if the BMI is below 15. Obese patients whose BMI is above 22 should limit their energy intake. Energy requirements also depend on the level of physical activity. |
