Principles of Nutritional Management in Patients with Liver Dysfunction—A Narrative Review

Abstract

According to studies, the liver’s ability to perform its physiological functions in the body determines the diet of patients with liver diseases. Malnutrition results from the liver’s inability to metabolize nutrients as a result of chronic liver dysfunctions. Objectives: Reviewing the data about diets and dietary supplements that manage liver dysfunctions nutritionally. Results: Malnutrition is particularly prevalent in cirrhosis patients, according to clinical studies. Because malnutrition has a significant negative impact on morbidity, mortality, and quality of life, it is crucial to evaluate all cirrhosis patients, regardless of etiology or severity. A term of supplemental enteral nutrition may be suggested for patients who do not achieve their nutritional objectives. A detailed nutritional and exercise assessment will enable the development of an individualized treatment plan that includes dietary and exercise plans. The dietary treatment should outline daily calorie targets with a focus on high-quality protein and address any vitamin and micronutrient deficiencies, with a diet high in those nutrients or supplements. Conclusions: While there is evidence to support the use of particular restricted dietary plans and dietary supplements to manage liver diseases, these findings should be regarded as preliminary until they are confirmed in larger randomized controlled clinical trials.
