High blood pressure, or hypertension, is often called a "silent" condition because it typically causes no obvious symptoms — yet it steadily damages blood vessels, the heart, kidneys, and eyes over time. Regular monitoring is the only reliable way to catch it early.
What Counts as High Blood Pressure?
Blood pressure is recorded as two numbers: systolic (pressure when the heart beats) over diastolic (pressure between beats). A reading consistently at or above 140/90 mmHg is generally considered high, though your doctor may use a lower threshold depending on your overall risk profile.
Why It's Called the "Silent" Risk
- Most people feel completely normal even with significantly elevated readings
- Occasional symptoms — headache, dizziness, or nosebleeds — usually appear only at very high levels
- Damage to arteries, the heart, and kidneys can accumulate for years before it's diagnosed
Who Is at Higher Risk
- Family history of hypertension or heart disease
- Being overweight or physically inactive
- High salt intake and low potassium intake
- Chronic stress and poor sleep
- Smoking and excessive alcohol consumption
- Age above 40, though it increasingly appears in younger adults
Why Untreated Hypertension Matters
Persistently high pressure forces the heart to work harder and gradually damages artery walls, raising the risk of heart attack, stroke, heart failure, and chronic kidney disease. Because it's symptomless, many people only discover it after a related complication occurs — which is why routine screening matters even when you feel fine.
Managing Blood Pressure
- Reduce salt intake and favour fresh, home-cooked meals
- Maintain a healthy weight through balanced nutrition and regular activity
- Exercise for at least 30 minutes most days of the week
- Limit alcohol and avoid smoking
- Manage stress through sleep, relaxation, and consistent routines
- Take prescribed medication exactly as directed — stopping abruptly can cause a dangerous rebound in pressure
When to See a Doctor Urgently
Seek immediate medical attention if a high reading is accompanied by severe headache, chest pain, shortness of breath, vision changes, or confusion — these can signal a hypertensive emergency.
Blood pressure is easy to check and, in most cases, manageable once identified. Regular screening — even without symptoms — remains the single most effective way to protect your heart over the long term.
