Hypertension (High Blood Pressure): What You Need to Know

High blood pressure often shows no symptoms but quietly raises your risk for heart attack, stroke, and kidney disease. Around one in three adults worldwide has elevated readings. That sounds scary, but most people can reduce risk with clear steps — lifestyle changes, monitoring, and sometimes medication.

How hypertension is measured and when it’s serious

Blood pressure has two numbers: systolic (top) and diastolic (bottom). Current guidelines usually flag readings of 130/80 mmHg or higher as hypertension. A single high reading doesn’t mean you have the condition. Doctors look for repeated high values, often measured both in the clinic and at home.

Measure correctly: sit for 5 minutes, feet on the floor, arm supported at heart level. Avoid caffeine, exercise, and smoking 30 minutes before checking. If you see values above 180/120 mmHg plus chest pain, severe headache, trouble breathing, or vision changes — get emergency care right away. That’s a hypertensive crisis.

Treatment: practical steps that actually help

First line actions are lifestyle changes you can start today. Cut back on salt (aim for under 2.3 g sodium/day if you can). Try the DASH-style approach: more vegetables, whole grains, lean protein, and fewer processed foods. Aim for 150 minutes of moderate exercise per week. Losing even 5–10% of body weight often lowers pressure. Limit alcohol, quit smoking, and work on sleep — untreated sleep apnea raises blood pressure.

If lifestyle changes aren’t enough, doctors add medication. Common drug classes include ACE inhibitors, ARBs, thiazide diuretics, calcium channel blockers, and beta blockers. Each works differently. Your doctor picks one based on other health issues, age, and possible drug interactions. Take meds exactly as prescribed — skipping doses is a common reason treatment fails.

Home monitoring matters. Log readings and share them with your clinician. Trends are more useful than single numbers. If readings climb despite lifestyle efforts and meds, your doctor will check for secondary causes like kidney problems, hormone issues, or certain medications that raise pressure.

Small, consistent actions add up. Swap processed snacks for fresh fruit. Walk after dinner. Check your pressure twice a week and bring results to appointments. Ask your clinician about side effects and how long it will take to see change.

Got questions about specific drugs, supplements, or risks with other conditions? Talk to your doctor or pharmacist. Hypertension is common, but manageable. With the right plan, most people can lower their risk and feel better every day.
