High blood pressure affects more than a billion people worldwide and remains one of the leading drivers of heart, kidney and brain disease. In this episode, I sit down with Dr Raymond Townsend, Professor of Medicine and Director of the Hypertension Programme at the University of Pennsylvania, to uncover what truly causes blood pressure to rise, how it damages the body, and what steps can help reverse or prevent it.
With more than four decades of clinical and research experience, Dr Townsend shares insights into the mechanisms of hypertension, the importance of early detection, and why empathy, consistency and accurate measurement matter as much as medication or diet. Together we explore how blood pressure control can protect vital organs, extend healthspan and reduce risk long before symptoms appear.
What We Cover
- What blood pressure really measures and how it relates to blood flow and vascular health
