Understanding Blood Pressure Levels: A Comprehensive Guide
Blood pressure is measured using two numbers: systolic pressure (the top number) and diastolic pressure (the bottom number). Systolic pressure represents the force when the heart beats, while diastolic pressure indicates the force when the heart rests between beats. These measurements are expressed in millimeters of mercury (mmHg). Understanding these numbers is essential for assessing cardiovascular health. What Are Normal Blood Pressure Levels? Normal blood pressure is typically defined as a systolic pressure below 120 mmHg and a diastolic pressure below 80 mmHg. Maintaining this range is associated with a lower risk of heart disease, stroke, and other health issues. Regular monitoring and a healthy lifestyle can help keep blood pressure within this optimal range. Elevated and High Blood Pressure Elevated blood pressure occurs when systolic pressure ranges between 120-129 mmHg and diastolic pressure remains below 80 mmHg. This stage is a warning sign, indicating a higher risk of developing high blood pressure if lifestyle changes are not made. High blood pressure, also known as hypertension, is categorized into two stages: Stage 1: Systolic pressure between 130-139 mmHg or diastolic pressure between 80-89 mmHg. Stage 2: Systolic pressure of 140 mmHg or higher or diastolic pressure of 90 mmHg or higher.
