Gut microbiota is a factor of risk for obesity and type 2 diabetes

Abstract

Gut microbiota (GM) is a set of bacteria which colonize the gastrointestinal tract. GM and its active metabolites take part in intestinal and hepatic gluconeogenesis, in the synthesis of incretin hormones, and affect the regulation of appetite. Thus, GM and its metabolites participate in the homeostasis of carbohydrates and fats. An imbalance in the set of the intestinal flora and a disturbance of the production of active metabolites sharply increases the risk of developing obesity and type 2 diabetes. There are conflicting data in the literature on the role of specific microorganisms in the development of metabolic disorders. Research is needed to identify specific types of bacteria and their active metabolites which affect the development of obesity and type 2 diabetes.
