Because malnutrition increases complications, one would theorize that providing nutrition support would improve nutritional status and therefore clinical outcomes. However, there are factors that interfere with improvement of nutritional status. First, achieving adequate nutrient intake can be difficult because the symptoms of liver failure (e.g., ascites, encephalopathy) impair a patient's appetite and food tolerance. In addition, there are potential impairments in nutrient absorption and metabolism induced by liver disease or associated complications such as infection. Nutrition supplementation, whether by the oral, tube feeding or parenteral route, may be necessary for individuals with serious liver disease to achieve adequate nutrient intake.
