The gut microbiome in obesity: new horizons in personalized medicine

Currently, disturbances in the composition and metabolic activity of the intestinal microbiota are considered a key modifiable factor in obesity and associated metabolic disorders. This review summarizes data on the characteristics and variability of the microbiota composition in individuals with obesity. The main mechanisms linking dysbiosis to metabolic disorders are discussed: changes in the production of short-chain fatty acids and other microbial metabolites, as well as the contribution of lipopolysaccharide-induced chronic inflammation. The influence of the microbiota on the regulation of appetite and eating behavior through the microbiota-gut-brain axis and intestinal hormones is discussed separately. Current approaches to the diagnosis of dysbiosis and potential strategies for correcting microbiome-associated disorders in obesity in the context of personalized medicine are presented.
