Nutritional Principles And Dietary Management In Patients With Liver Disease

Abstract

Liver diseases are characterized by complex metabolic, hormonal, and inflammatory alterations that profoundly affect nutritional status, body composition, and clinical outcomes. Malnutrition and sarcopenia are highly prevalent in chronic liver disease and independently predict morbidity, mortality, and reduced quality of life. This review synthesizes contemporary evidence on nutritional disturbances and dietary interventions in liver disease. A structured narrative analysis of international and regional literature examined energy and protein metabolism, micronutrient deficiencies, muscle wasting, and disease-specific dietary strategies. The findings indicate that adequate energy and protein intake, appropriate meal timing, and individualized nutritional support reduce catabolism, preserve muscle mass, and improve functional status. Targeted correction of vitamin D and zinc deficiency may further support metabolic and immune function
