Mechanisms of Hypertension in Women: Interactions Between Vascular Ageing, Metabolic Dysfunction, and Hormonal Regulation

Purpose: Hypertension in women is a dynamic, hormone sensitive condition shaped by cumulative physiological changes across the life course. This review summarises current evidence relating vascular ageing, hormonal regulation, metabolic dysfunction, and reproductive history to blood pressure regulation in women. Materials and Methods: A narrative review of the literature was conducted using PubMed, Scopus and Google Scholar. Clinical, epidemiological, and mechanistic studies were synthesised to evaluate factors influencing hypertension in women. Reports in which menopausal status was not defined, or previous reproductive milestones were not documented, were excluded or interpreted with caution. Results: Evidence suggests that menopause, vascular ageing, metabolic dysfunction, androgen to oestrogen balance, and reproductive history interact to influence endothelial function, neurohormonal regulation, renal sodium handling, and vascular resistance. Ageing-related mechanisms, including cellular senescence, chronic low-grade inflammation, and genetic susceptibility, may contribute to increased cardiovascular risk. Hypertensive disorders of pregnancy identify women who are at higher risk of developing cardiovascular disease later in life and provide an opportunity for earlier risk assessment and prevention. Emerging therapies, including GLP-1 receptor agonists and SGLT2 inhibitors, may offer additional options for improving cardiovascular risk management, although their role in sex-specific prevention remains an evolving area of research. Conclusions: Hypertension in women is best understood within a life-course framework. Incorporating reproductive history, menopausal status, metabolic health, and emerging risk markers may improve cardiovascular risk assessment and support earlier intervention.
