Malnutrition leading to growth failure is one of the main problems in maintainig children with chronic liver diseases. The pathogenesis of malnutrition is complex and includes reduced calorie intake, fat malabsorption, impaired protein metabolism and increased energy expenditure. The nutritional status is an important risk factor for survival post liver transplantation. Aggressive nutritional support with careful monitoring is essential, particularly where liver transplantation is considered. When the oral nutrition is inadequate, the enteral feeding with nocturnal intragastric tube should be started. In case of gastrointestinal intolerance, severe malnutrition and gastrointestinal bleeding, parenteral nutrition should be considered.
