Hypertension: Clinical Review for Nurses & Medical Assistants.

Elevate your understanding of High Blood Pressure. A comprehensive review of causes, advanced diagnostics, and current evidence-based management strategies for clinical practice.

High blood pressure, also known as hypertension, is one of the most common yet often overlooked health problems worldwide. It’s called the silent killer because it may not show noticeable symptoms until it causes serious complications like stroke, heart attack, or kidney failure. Understanding its causes, warning signs, and prevention can save lives.

Causes of High Blood Pressure.

• Hypertension can be primary (essential) or secondary:

• Primary hypertension – develops gradually over years, often with no single identifiable cause.

• Secondary hypertension – caused by another medical condition, such as:

• Kidney disease.

• Hormonal disorders (e.g., thyroid problems, Cushing’s syndrome).

• Certain medications (e.g., birth control pills, NSAIDs).

• Sleep apnea.
