Hypertension and the Gut Microbiome

Published: July 17, 2025

Figure1. Potential interventions and complicating factors that target the gut microbiota to influence blood pressure. Potential interventions that have been reported to be beneficial to hypertension in experimental rodents and humans. Salt, as a complicating factor that alters the gut microbiota and activates immune responses, is discussed. The listed factors represent those discussed in this review and do not encompass all potential contributors. FMT indicates fecal microbiome transplantation; and SCFA, short-chain fatty acid.
  • Recent advances in gut microbiome and hypertension research suggest a novel therapeutic opportunity: targeting the gut microbiome to control blood pressure.
  • Short chain fatty acids (e.g. acetate, propionate, butyrate) attenuate blood pressure in rodent models. In humans, prebiotic supplements that increase short-chain fatty acid production appear to reduce blood pressure, whereas direct oral butyrate supplementation may raise it.
  • Fecal microbiome transplantation temporarily lowers blood pressure in patients with hypertension. Supplementation with prebiotics may enhance the blood pressure-lowering effect. Further research is needed to determine how these and other microbiome-targeted therapies can be effectively translated into clinical practice.
