Abstract
Chronic diseases have emerged as a significant challenge in global public health due to their complex etiologies, prolonged disease courses, and high treatment costs. With the aging population and changes in lifestyle, the number of patients with chronic diseases has increased dramatically, which has brought heavy burden to families and society. Chronic diseases are often accompanied by digestive and absorptive disorders as well as metabolic disorders, resulting in insufficient nutrient intake, further worsening the condition and weakening the physique. Therefore, the importance of nutritional intervention in chronic disease management has become increasingly prominent. As an important means of nutritional intervention, enteral nutrition plays a key role in improving the nutritional status of patients, promoting rehabilitation, shortening hospital stay and so on, thereby providing a new solution for chronic disease management. This article reviews the current application status, mechanism of action and comprehensive benefit of enteral nutrition in the clinical management of chronic diseases. Through systematic review and analysis of existing research findings, the specific application effects and mechanisms of enteral nutrition in chronic disease management are clarified. This review aims to promote the popularization and application of enteral nutrition, in order to effectively improve patients' treatment outcomes and quality of life, provide scientific evidence for the optimization of clinical management strategies for chronic diseases, and offer theoretical support for the development of enteral nutrition products, and thereby drive the continuous improvement of chronic disease management.
