The Prospect of Non-Alcoholic Fatty Liver Disease in Adult Patients with Metabolic Syndrome: A Systematic Review.

Abstract

In recent years, there has been an increasing trend in the development of non-alcoholic fatty liver disease (NAFLD) due to lifestyle changes. The limited treatment option for the disease makes it challenging to manage. This study aims to summarize the relationship between NAFLD and metabolic syndrome (MetS) and to give a clear idea of the risk factors in this systematic research. The five databases screened were PubMed, Google Scholar, Science Direct, and BMC using keywords and Medical Subject Heading (Mesh) combinations. The keywords used are "Metabolic Syndrome,""Syndrome X,""Insulin Resistance,""Obesity,""Type 2 Diabetes,"and "Dyslipidemia."Articles underwent a detailed process of screening and quality appraisal. Using the English language as a primary filtering parameter, papers over the last 13 years, dating from 2010 to 2023, are the basis of this review. We reviewed all possible human studies documenting NAFLD with a component of MetS. A total of1106 papers were identified. After duplicate removal, 995 articles underwent a rigorous review, and35 articles were chosen for quality appraisal.A total of 15 articles are part of this systematic review.This systematic review strongly concludes that NAFLD predominates in MetS patients. The pathophysiology and insulin resistance that is shared by the two conditionsas well as the fact that obesity is at the center of both is the connecting factor in this. Besides various demographic and risk factors, physical activity and diet also play a role in the development of NAFLD. Consequently, more studies on this relevant topic are needed.
