RESUMO
OBJECTIVE: The aim: To analyze the relationship between non-alcoholic fatty liver disease and changes in the gut microbiota. PATIENTS AND METHODS: Materials and methods: The publications of domestic and foreign editions in the databases of the United European Gastroenterology (UEG) Journal, PubMed, MEDLINE, Web of Science were processed and analyzed. CONCLUSION: Conclusions: In recent years, non-alcoholic fatty liver disease was placed among the important diseases in gastroenterology. During this time, more and more data appear on the link between changes in the human intestinal microbiome and the development of metabolic diseases, including NAFLD. Contemporary research has indeed found evidence of such a relationship. Thus, some strains of microorganisms have been identified in more detail, which directly or indirectly affect the development or course of the above-mentioned disease. For a better understanding of the strategies for the treatment of pathologies, it is necessary to delve into the study of etiological factors, therefore, NAFLC cannot be considered a pathology that has been sufficiently studied. Indeed, recent data indicate that the development and severity of the course of the disease are not always associated with the physiological processes already known to us.
