Non-alcoholic fatty liver disease (NAFLD) is difficult to define, has intricate pathogenesis, has a high outbreak, and few acquiesced treatments are available. Thus, this condition has posed a great challenge in our time. The non-alcoholic fatty liver disorder is correlated with obesity and insulin resistance and is emerging as the most ordinary form of chronic liver disorder in grown-ups and kids alike. The Pubmed, NCBI, Medline, Cochrane databases, and Embase were searched for patients' studies with nonalcoholic fatty liver disorder. Management options, Incidence, and causes were all investigated. NAFLD is a quickly rising reason for a chronic liver disorder. It is a complicated condition that encounters multiple challenges in its management and assessment. If it's not treated on time, hepatic steatosis may progress to NASH and eventually liver cirrhosis. Controlling this illness requires a multidisciplinary technique. We hope that treatment options for advanced stages of the condition will meliorate in the next decade.
