Abstract: The gut microbiota is a powerful "organ" composed of prokaryotic organisms (bacteria), eukaryotic microorganisms (including fungi and protozoa) and viruses, which plays a crucial role in the nutrition metabolism, maintenance of the integrity of intestinal mucosal barrier, and immune regulation of the body. Researches have shown that intestinal microecology is related to the pathogenesis of many diseases, such as neuropsychiatric diseases, autoimmune diseases, cancer and chronic metabolic diseases. Recent studies have found that gut microbiota can regulate hemodynamics through the oxidation of trimethylamine and short chain fatty acids. At the same time, gut microbiota disorder and translocation can activate the body's inflammatory response, affecting the stability of the body's hemodynamics.In this article, we summarize the relationship between gut microbiota and hemodymamics, in order to provide reference for further research.
