Gut microbiota: a potential new regulator of hypertension

Frontiers in Cardiovascular Medicine

Hypertension is a significant risk factor for cardiovascular and cerebrovascular diseases and has become a global public health concern. Although hypertension results from a combination of factors, the specific mechanism is still unclear. We provide a summary of the composition and physiological role of gut microbiota.
