Why is hypertension called hypertension?
The term "hypertension" comes from the Greek words "hyper," meaning "high" or "above," and "tensio," meaning "pressure." Hypertension is aptly named as it refers to the elevated blood pressure in the arteries.
Blood pressure is created when the heart pumps blood through the arteries, and it is measured in millimeters of mercury (mm Hg). Hypertension occurs when the blood pressure is consistently higher than normal, leading to increased pressure on the walls of the arteries. This can cause various cardiovascular problems and is why hypertension is often referred to as "high blood pressure."
Blood pressure is categorized as follows:
- Normal blood pressure: Less than 120/80 mm Hg
- Elevated blood pressure: 120-129/less than 80 mm Hg
- Stage 1 hypertension: 130-139/80-89 mm Hg
- Stage 2 hypertension: 140/90 mm Hg or higher
Sustained hypertension can put a strain on the heart and damage blood vessels, leading to serious health complications such as heart attacks, strokes, kidney disease, and vision loss. Therefore, early detection and appropriate management of hypertension are crucial for maintaining overall health and reducing the risk of cardiovascular events.
