Understanding Blood Pressure
Blood pressure refers to the force exerted by circulating blood against the walls of the body's arteries, the largest blood vessels. It is a vital sign and an indication of heart health. Blood pressure readings are given as two numbers: systolic and diastolic. The systolic blood pressure is the pressure when the heart beats while pumping blood; the diastolic blood pressure measures the pressure when the heart is at rest between beats.
Systolic Blood Pressure: Indicates how much pressure blood is exerting against artery walls when the heart beats.
Diastolic Blood Pressure: Reflects the pressure in the arteries when the heart rests between beats.
A normal blood pressure level is less than 120/80 mmHg. Here are the categories for blood pressure levels in adults:
Category Systolic (mm Hg) Diastolic (mm Hg) Normal <120 <80 Elevated 120-129 <80 Hypertension Stage 1 130-139 80-89 Hypertension Stage 2 ≥140 ≥90 Hypertensive Crisis >180 >120
High blood pressure, also known as hypertension, can lead to health issues such as heart disease and stroke. It is often called the "silent killer" because it may have no symptoms. Managing blood pressure is crucial for maintaining heart health and reducing the risk of these severe consequences. Regular monitoring can help to detect changes early on, allowing for timely intervention and management.
The Role of Diet in Managing Blood Pressure
Diet plays a crucial role in the management of blood pressure, where specific nutrients impact blood pressure levels, and certain foods are advisable to avoid to maintain cardiovascular health.
