Nutrition as Therapy in Liver Disease

Purpose: The importance of nutrition is often underrecognized in the routine clinical care of patients with chronic liver disease. Nutrition therapy plays a significant role in the management of alcohol-related liver disease and nonalcoholic fatty liver disease. In patients with cirrhosis from any etiology, malnutrition and sarcopenia are directly related to mortality, and nutritional interventions play an important role in the management of these patients. This review explores the role of nutritional intervention as adjuvant therapy across all chronic liver disease. Methods: A narrative, qualitative systematic review was performed via searches of PubMed for nutritional aspects in the care of chronic liver disease. Findings: Nutritional therapy plays a critical role in the management of chronic liver disease. In nonalcoholic fatty liver disease, specific macronutrient management can lead to weight loss and improved outcomes in these patients. In patients with alcohol-related liver disease, chronic cholestatic liver disease, and decompensated cirrhosis, caloric and protein intake plays a vital role improving outcomes in these patients. Micronutrient deficencies are also common in these patients and require supplementation to prevent other complications of malnutrition. Assessment and management of nutrition should accompany the typical care plan of patients with chronic liver disease. (C) 2022 Elsevier Inc.
