High blood pressure, or hypertension, happens when the force of blood pushing against artery walls stays too high over time. Your doctor measures this with two numbers—the pressure when your heart beats and the pressure when it rests between beats. Many people have hypertension without noticing symptoms, which is why it's sometimes called a silent condition. Understanding what causes high blood pressure and how it affects your body helps explain why managing it matters for your long-term health.

These articles explore what happens inside your body when blood pressure rises, which factors increase your risk, and how different treatments work to bring pressure down. You'll find information about lifestyle changes that can make a difference, how medications function, and what the numbers on a blood pressure reading actually mean for your health.
