Understanding High Blood Pressure

High blood pressure, or hypertension, occurs when the force of blood pushing against your artery walls stays higher than it should. Blood pressure is measured with two numbers: systolic (the pressure when your heart beats) and diastolic (the pressure when your heart rests between beats).
Why It Matters
High blood pressure is often called a “silent killer” because most people do not feel symptoms. Many adults have elevated readings without realizing it, which makes regular monitoring important.
When blood pressure stays high over time, it can damage blood vessels and organs. Serious complications may develop, including heart attack, stroke, heart failure, kidney disease, and vision problems. Preventing or controlling high blood pressure helps reduce the risk of these long-term health issues.
What Counts as High
Blood pressure ranges fall into several categories:
- Normal: Systolic below 120 and diastolic below 80 mmHg
- Elevated: Systolic 120 to 129 and diastolic below 80 mmHg
- Stage 1 Hypertension: Systolic 130 to 139 or diastolic 80 to 89 mmHg
- Stage 2 Hypertension: Systolic 140 or higher, or diastolic 90 or higher
A single high number, either systolic or diastolic, may be enough for a diagnosis depending on a person’s age and overall health.
What Causes It
For many people, there is no clear cause. This is known as primary or essential hypertension. Age, family history, and genetics play a role, but lifestyle factors also have a significant impact.
Common contributors include lack of physical activity, excess sodium in the diet, being overweight, tobacco use, and frequent alcohol consumption. Some medical conditions, such as kidney disease or hormonal disorders, can lead to secondary hypertension. Certain medications may also raise blood pressure.
Why It Is Often Silent
Most people with high blood pressure feel completely normal. Years can pass without any clue that something is wrong. In rare cases, extremely high blood pressure may cause dizziness, chest pain, vision problems, swelling, shortness of breath, or signs of stroke. These require immediate medical care.
How to Manage and Reduce Risk
Regular blood pressure checks are one of the most effective ways to protect your health. A healthcare professional can help interpret readings and determine whether treatment is needed.
Healthy habits play a major role in prevention and management. Eating a balanced diet, limiting sodium, staying active, reaching or maintaining a healthy weight, avoiding tobacco, and limiting alcohol can all help lower blood pressure. When lifestyle changes are not enough, medications may be prescribed to keep it under control.
With regular monitoring and the right care plan, most people with high blood pressure can live healthy, active lives.
