Dear Reader,
Blood pressure is the driving force that gets oxygen-rich blood — the body’s life source — to your organs and tissues and delivers waste to your lungs, liver and kidneys for removal. With the right amount of pressure, the proper amount of blood travels throughout the body.
But when blood pressure is too high, blood flow to organs and tissues also becomes too high. In response, the muscular walls in the blood vessels narrow. This action restores balance in your blood flow, which is good, but the longer the blood vessels do this, the more stress they experience. Over time, the walls of the blood vessels thicken. This makes it hard to achieve proper blood flow, and blood pressure rises even more. In time, the increased stress on the blood vessels leads to organ damage.
This is the cycle of high blood pressure — and why it’s so important to treat and prevent it. With Mayo Clinic on High Blood Pressure at your side, you'll have an essential resource to prevent and manage hypertension effectively. You’ll learn how it’s diagnosed and treated, how to prevent conditions associated with it, and what puts you at risk.
