Nutrition Therapy and Dialysis Melinda S. Leone, MS, RD St. Joseph's Regional Medical Center Division of Nephrology Paterson, NJ 07503 leonem@sjhmc.org Objectives Participant will be able to describe the importance of nutrition intervention in patients with ESRD Participant will be able to identify the components of a nutritional assessment Participant will be able to identify the components of the renal diet and the role of the dietitian Does Nutrition Status Matter? YES! Nutritional indicators can be directly linked to patient status and outcome Protein-Energy Malnutrition (PEM) BMI Albumin Potassium Phosphorus Calcium 2 3, 4 5 1 Renal Osteodystrophy Hyperphosphatemia Vascular and non-vascular calcification Hypocalcemia Secondary Hyperparathyroidism Bone Disease Low bone mass and density Osteitis fibrosa cystica 5 Protein Energy Malnutrition6 PEM Malnutrition PEM: marasmus-kwashiorkor muscle/fat wasting weight loss Marasmus: Inadequate nutrient intake Kwashiorkor: Inadequate protein intake Cachexia Causes of Malnutrition Uremic Syndrome Malaise Weakness Nausea
