High Blood Pressure: Control It Before It Harms You

What does it mean?

Hypertension is high blood pressure — the force of blood against the artery walls stays too high over time. It usually has no symptoms, so most people feel fine even with dangerously high readings, which is why it is called the silent killer.

Blood pressure is the force of blood pushing against your artery walls. When it stays high over time, it silently damages the heart, brain, kidneys and eyes — which is why hypertension is called the "silent killer." Most people feel perfectly fine even with dangerously high readings; the first symptom is often a heart attack, stroke or kidney failure. Globally, an estimated 1.4 billion adults aged 30–79 live with hypertension (ACC summary of the 2025 guideline), and in Pakistan salty diets, obesity and low treatment rates make it one of our most under-controlled health problems. The good news: it is highly treatable with lifestyle change and safe, affordable medicines.

Common causes

• 1Know the categories
  (2025 AHA/ACC guideline): Normal: below 120/80 mmHg Elevated: 120–129 / below 80 Stage 1 hypertension: 130–139 / 80–89 Stage 2 hypertension: 140 or higher / 90 or higher
• 2The treatment target is below 130/80.
  The 2025 AHA/ACC guideline reaffirms <130/80 mmHg for most adults, with encouragement to get as close to 120/80 as possible — because every 10 mmHg drop in systolic pressure cuts heart disease risk by ~17%, stroke by ~27% and heart failure by ~28%.
• 3Salt matters more than you think.
  WHO recommends less than 5 grams of salt per day (about one teaspoon, including hidden salt) — yet most people eat 9–12 grams. In Pakistani cooking, salt hides in pickles (achar), papad, processed snacks, stock cubes and restaurant food, not just the salt shaker.
• 4DASH-style eating lowers pressure.
  Plenty of vegetables, fruit, daal/beans, whole grains and low-fat dairy; less red/processed meat, fried food and sweets. Potassium-rich foods (bananas, oranges, potatoes, daal) help — unless your doctor has restricted potassium because of kidney problems.
• 5Move regularly.
  At least 150 minutes per week of moderate activity (brisk walking) plus muscle-strengthening activity lowers blood pressure and protects the heart.
• 6White-coat vs. masked hypertension are real.
  Some people read high only in the clinic (white-coat) but normal at home; others read normal in the clinic but high at home (masked — more dangerous because it goes untreated). This is why the 2025 guideline strongly emphasizes out-of-office (home) measurements to confirm diagnosis.
• 7Medicines work — but only if taken daily.
  Blood pressure medicines prevent strokes and heart attacks; stopping them because "I feel fine" is one of the commonest causes of uncontrolled pressure. Never stop or adjust on your own.

When to worry

Prevention & practical tips

• ✓Learn correct home BP technique (this is where most readings go wrong): Rest quietly for 5 minutes before measuring; empty your bladder first. No caffeine, smoking or exercise for 30 minutes before. Sit with back supported, feet flat on the floor, arm supported at heart level; use the correct cuff size on a bare arm. Take two readings, 1–2 minutes apart, and record both. Measure at the same times daily (e.g., morning before medicine, evening before dinner). Use a validated upper-arm digital monitor — not wrist or finger devices.
• ✓Cut salt smartly: remove the salt shaker from the table, halve salt in cooking gradually, skip achar/papad with meals, rinse canned foods, and read labels on snacks and processed foods.
• ✓Eat the DASH way with desi foods: more sabzi, salads, daal and fruit; modest roti portions; low-fat dahi; less ghee/oil and fried items.

• ✓Walk 30 minutes most days; add simple strength activity (bodyweight exercises) twice a week.
• ✓Limit alcohol (ideally avoid), quit tobacco completely — including naswar and paan with tobacco — and manage stress with sleep, breathing exercises or prayer/meditation routines.
• ✓Take medicines exactly as prescribed, at the same time daily. Use a pill organizer or phone alarm. Tell your doctor about side effects instead of stopping.
• ✓Bring your home BP log to every appointment — treatment decisions should be based on your usual readings, not one clinic number.
