Different approaches to change gut microbiota and its influence on metabolic disorders

Abstract

Obesity and type 2 diabetes mellitus (T2D) are two non-infectious pandemics of the XXI century. Despite a large number of studies devoted to the development of obesity and T2D, it seems complicated to overcome the ongoing growth in the number of cases. In these situations it is necessary to investigate new approaches for the prevention and treatment of such diseases. One of these approaches is to study the role of gut microbiota in the disturbance of carbohydrate and lipid metabolism. This manuscript describes the role of the microbiota in obesity and T2D. The aim of the review was to describe various approaches to change the composition of the gut microbiota and to determine its impact on metabolic risks. To assess the relationship between T2D development and changes of microbiota composition we considered a number of studies devoted to the consequence of these pathophysiologic mechanisms in various situations: the effect of drug treatment, bariatric surgery and microbiota transplantation. Possible metabolically protective gut microbiota composition is discussed.
