Investigating causal links between gastroesophageal reflux disease and essential hypertension.

Abstract

Gastroesophageal reflux disease (GERD) is a prevalent global health concern with a rising incidence. Various risk factors, including obesity, hiatal hernia, and smoking, contribute to its development. Recent research suggests associations between GERD and metabolic syndrome, cardiac diseases, and hypertension (HTN). Mechanisms linking GERD to HTN involve autonomic dysfunction, inflammatory states, and endothelial dysfunction. Furthermore, GERD medications such as proton-pump inhibitors may impact blood pressure regulation. Conversely, antihypertensive medications like beta-blockers and calcium channel blockers can exacerbate GERD symptoms. While bidirectional causality exists between GERD and HTN, longitudinal studies are warranted to elucidate the precise relationship. Treatment of GERD, including anti-reflux surgery, may positively influence HTN control. However, the interplay of lifestyle factors, comorbidities, and medications necessitates further investigation to comprehensively understand this relationship. In this editorial, we comment on the article published by Wei et al in the recent issue of the World Journal of Clinical Cases. We evaluate their claims on the causal association between GERD and HTN.
