1. Understanding High Blood Pressure

1. Understanding High Blood Pressure

High blood pressure, also known as hypertension, is a common health condition that affects millions of people worldwide. It is characterized by persistently elevated levels of arterial blood pressure, which can lead to serious health complications if left untreated. Blood pressure is measured in millimeters of mercury (mmHg) and is typically expressed as two numbers: systolic pressure (the higher number) and diastolic pressure (the lower number). The American Heart Association defines high blood pressure as a reading of 130/80 mmHg or higher.

There are two main types of high blood pressure:

1. Primary (essential) hypertension: This is the most common form and has no identifiable cause. It is often linked to genetic factors, lifestyle choices, and environmental influences.

2. Secondary hypertension: This type is caused by an underlying medical condition or the use of certain medications.

Risk factors for developing high blood pressure include age, family history, obesity, physical inactivity, tobacco use, excessive alcohol consumption, high salt intake, and stress. High blood pressure is often referred to as the "silent killer" because it typically shows no symptoms until it causes significant damage to the body.

If not managed properly, high blood pressure can lead to various health issues, such as heart disease, stroke, kidney disease, and vision problems. Therefore, it is crucial to monitor and control blood pressure levels to prevent these complications. Regular check-ups, maintaining a healthy lifestyle, and adhering to prescribed medications are essential for effective high blood pressure management.
