Nonalcoholic fatty liver disease (NAFLD) is considered the most prevalent chronic hepatic disease, as it has been estimated that one of four individuals in the general population has been affected by NAFLD. The evolution of the referred entity, which includes nonalcoholic steatohepatitis (NASH) and hepatic fibrosis, may have crucial and even fatal consequences, leading to cirrhosis and hepatocellular carcinoma. Although NAFLD has also been linked with cardiovascular and renal diseases, and all-cause mortality increment, pharmacological therapy is as yet an unfulfilled demand. Since NAFLD is closely associated with type 2 diabetes mellitus (T2DM), a variety of anti-diabetic drugs have been investigated for their effectiveness towards NAFLD. Sodium-glucose co-transporter 2 inhibitors (SGLT-2i) improve blood glucose levels through increasing renal glucose excretion and they are recommended as one of standard therapeutic categories for T2DM patients. Based on preclinical animal studies, SGLT-2i have shown a beneficial effect on NAFLD, inducing histologically proven amelioration of hepatic steatosis, inflammation and fibrosis. Promising data have been also derived by clinical trials, which have indicated a potentially beneficial effect of SGLT-2i on NAFLD, at least in terms of liver function tests and imaging. Thus, it is not strange that there are many ongoing trials on the effect of various SGLT-2i in NAFLD. In conclusion, current evidence concerning the effect of SGLT-2i on NAFLD is encouraging; however, data from ongoing clinical trials with histological endpoints are awaited.
