Blood Pressure Levels Overview
Blood pressure levels reflect the force of blood pushing against artery walls as the heart beats and rests. Readings are recorded as two numbers – systolic over diastolic – and measured in millimeters of mercury (mm Hg).
Monitoring blood pressure levels over time helps identify patterns, assess cardiovascular risk and guide treatment decisions. Because high blood pressure often develops without noticeable symptoms, routine measurement plays a critical role in protecting long-term health.
Blood Pressure Categories
Blood pressure readings fall into specific categories that help determine whether levels are normal or require attention. Understanding these ranges provides important context for evaluating your risk and next steps.
Systolic vs. Diastolic
Each blood pressure reading includes two numbers that reflect different phases of heart function. Knowing the difference between systolic and diastolic pressure helps you better understand what your results mean.
