what causes high blood pressure?

High blood pressure, or hypertension, often stems from a combination of genetic, lifestyle, and environmental factors that strain the cardiovascular system over time.

Primary Causes

Lifestyle factors dominate most cases. Smoking narrows blood vessels, forcing the heart to pump harder, while excess body weight increases blood volume and stress on arteries. A high-sodium diet causes fluid retention, elevating pressure, and chronic inactivity weakens the heart's efficiency.

Medical Risk Factors

Underlying conditions play a key role. Chronic kidney disease impairs blood regulation, and conditions like sleep apnea or thyroid disorders disrupt hormone balance, raising pressure. Family history and older age heighten susceptibility, with genetics influencing artery stiffness.

Secondary Contributors

• Alcohol and stress: Excessive drinking (over 1-2 drinks daily) constricts vessels, and chronic stress surges adrenaline.

• Medications and demographics: Certain drugs like decongestants or birth control narrow arteries; African Americans face higher rates.

• Illegal substances: Cocaine or amphetamines damage vessels acutely.

TL;DR: Lifestyle changes like diet and exercise address 90% of cases, but consult a doctor for personalized risks.
