A review on the effect of gut microbiota on metabolic diseases.

ABSTRACT

Human gut microbiota are a huge and complex microbial community, which is recognized to play a significant role in regulating host metabolism. However, the destruction of gut microbiota leads to the pathological response of host, and thus results in a variety of metabolic diseases. This article gives a brief review of research progress on gut microbiota and some main metabolic diseases, including osteoporosis, obesity, type 2 diabetes, non-alcoholic fatty liver, and hypertension, with a specific focus on the effect of gut microbiota on diseases' occurrence and development. In addition, this review article also shows some case studies on the regulation of gut microbiota by new means, such as fecal microbiota transplantation and oral probiotics. Although gut microbiota are considered as a promising novel target for the treatment of metabolic diseases, it is also necessary to encourage further studies to provide more valuable data for guiding the application of gut microbiota on disease therapy in future.
