Gastrointestinal peptides and nonalcoholic fatty liver disease

In this review, authors have selected from literature the most recent and suggestive studies on therapy of nonalcoholic fatty liver disease (NAFLD). The selected interventions regulate the action of gastrointestinal peptides, such as gastric inhibitory polypeptide (GIP), nesfatin, peptide YY, cholecystokinin, and glucagon-like peptide 1 (GLP-1). These hormones have been found frequently modified in obesity and/or type 2 diabetes mellitus, morbidities mostly associated with NAFLD. This disease has a very high prevalence worldwide and could evolve in a more severe form, that is, nonalcoholic steatohepatitis, characterized by inflammation and fibrosis. The findings shown by this article describe the metabolic effects of new drugs, mainly but not only, as well of some old substances.
