Management of nutrition in patients with renal failure is challenging as malnutrition occurs in up to 40% of such patients and is associated with increased morbidity and mortality. Malnutrition has multiple contributing factors, including decreased food intake due to gastrointestinal symptoms. Providing appropriate calorie and protein intake tailored to the patient's stage of kidney disease is important to permit adequate nutrition without unnecessary restrictions. Nutritional assessment, monitoring guidelines for calories, proteins and minerals, and specialized nutrition support are crucial for managing the nutrition of renal failure patients.
