Liver plays a central role in regulation of nutrition.Due to metabolic abnormalities,patients with end-stage liver disease often demonstrate undernutrition,which has a close relationship with the prognosis of the patients.Correct nutritional assessment and nutrition support is therefore very important.Dietary intake alone could not meet the nutritional needs of patients with end-stage liver disease.In recent years,the use of enteral and parenteral nutrition formulation has significantly improved the nutritional status of such patients,but there still lacks a gold standard. How to develop appropriate nutrition support regimens is a challenge for clinicians.This paper summarizes nutrition-related issues in patients with end-stage liver disease,aiming to provide a reference for individualized nutritional intervention for patients with end-stage liver disease.
