Abstract
When liver disease is severe, the prognosis can be worse if the patient is malnourished. Adequate nutritional support for patients with liver diseases can improve the patient's condition and prognosis. In the case of liver cirrhosis, malnutrition can occur due to a variety of causes, including poor oral intake, maldigestion, malabsorption, associated renal disease, and metabolic abnormalities. For a nutritional assessment, it is important to check the dietary intake, change in body composition, including anthropometry, and a functional assessment of muscle. Counselling and oral or enteral nutrition is preferred over parenteral nutrition as in other diseases. If esophageal varices are present, care should be taken when installing a feeding tube, but if there are ascites, percutaneous endoscopic gastrostomy is contraindicated because of the risk of complications. Calories of 30–35 kcal/kg/day and protein from 1.2 to 1.5 g/kg/day are appropriate. Protein restriction is unnecessary unless the hepatic encephalopathy is severe. A late evening snack and branched chain amino acids can be helpful. In the case of cholestasis, the supply of manganese and copper should be restricted. Sarcopenia in patients with liver cirrhosis is also prevalent and associated with the prognosis.
