High Blood Pressure, the Condition With No Symptoms

High blood pressure, or hypertension, means the force of blood pushing against your artery walls stays too high, generally 140/90 mmHg or above on repeated readings. It almost never causes symptoms, yet it damages the heart, brain, kidneys and eyes for years. Blood pressure is measured, not felt.

Why is high blood pressure called the "silent killer"?

Because the damage runs well ahead of the symptoms. Arteries stiffen, the heart muscle thickens and the kidney filters wear out long before anything hurts. Many people find out they have hypertension only when a heart attack, a stroke or a kidney problem brings them into hospital.

The World Health Organization lists raised blood pressure among the leading risk factors for cardiovascular death worldwide, and notes that a large share of people living with it are undiagnosed or untreated. In our region the reason is usually simple: nobody checked. A blood pressure cuff takes one minute and costs almost nothing, and it is the only honest way to find the problem.

What are the symptoms of high blood pressure?

Most people have none. That is the whole difficulty. When symptoms do appear they are vague and unreliable: headache, dizziness, a heavy feeling in the neck, blurred vision, nosebleeds, or breathlessness on exertion.

Patients in Abbottabad often describe:

• Headache at the back of the head, worst in the morning
• Heaviness or tightness across the neck and shoulders
• Dizziness or a spinning feeling
• Nosebleeds
• Blurred or dim vision
• Breathlessness climbing stairs or walking uphill

Here is the trap. Every one of those feelings happens daily in people whose blood pressure is perfectly normal. You cannot read your pressure from how you feel, and you must never adjust your tablets because of a headache. Only the number tells the truth.

What causes high blood pressure, and what raises the risk in Pakistan?

For most adults there is no single cause. Pressure creeps up over years through salt, weight, inactivity, stress and inherited tendency. In a smaller group a specific cause is found, such as kidney disease, a thyroid problem or sleep apnoea, which is why a first diagnosis deserves a proper assessment rather than an instant prescription.

Locally important risk factors include:

• Salt. The World Health Organization recommends less than 5 grams a day, about one level teaspoon from all sources. Our diets carry far more, and most of it is hidden: salan masala, achar, chatni, papar, namkeen, salted lassi, bakery rusk and biscuits, packaged masala mixes, stock cubes, and the pinch added at the table or sprinkled on fruit.
• Weight around the waist, which raises pressure even in people who do not look heavy.
• Very little daily movement. Long hours sitting, transport everywhere, no walking routine.
• Diabetes and high cholesterol, which usually travel alongside hypertension.
• Smoking and naswar, which stiffen arteries and multiply overall heart risk.
• Family history, with hypertension in parents or siblings, often starting young.
• Medicines and products: frequent painkillers for joint pain, some herbal or unlabelled hakeemi preparations, and steroid-containing products.

How should I measure my blood pressure at home?

Sit quietly for five minutes first, back supported and feet flat on the floor, and do not talk during the reading. Use a validated upper-arm cuff machine rather than a wrist device, with your arm resting at heart level. Take two readings a minute apart and write both down.

A few rules make home readings trustworthy:

• Measure twice a day, morning and evening, for seven days before a review appointment.
• Record every reading, including the ones you do not like. A diary of only good numbers is useless.
• Do not measure straight after tea, a cigarette, naswar, exercise or a stressful phone call.
• Use the right cuff size. A cuff too small for a large arm reads falsely high.
• Do not re-check ten times in a row. Repeated anxious readings drift upward and tell you nothing.

Home averages usually run a little lower than clinic readings, so bring the whole list and let your cardiologist read it against your target.

When should you go to the Emergency?

Go at once. Call 1122 or go straight to DHQ Hospital Abbottabad Emergency if a very high reading comes with chest pain, severe headache with vomiting, breathlessness at rest, confusion, blurred vision, or sudden weakness, numbness or drooping on one side of the body.

Those last symptoms may be a stroke, where minutes count as much as they do in a heart attack. Do not drive yourself, and do not wait to see whether the number settles. A high reading with no symptoms at all is a different situation. It needs an urgent clinic review, repeated measurement and a treatment plan, not an emergency dash and not extra tablets taken on your own.

How is high blood pressure diagnosed?

Diagnosis needs repeated readings on separate occasions, not a single number. Once hypertension is confirmed, the next job is checking whether it has already affected the organs it damages, and whether a treatable underlying cause is hiding behind it. NICE guidance supports confirming raised clinic readings with out-of-office measurement before anyone starts lifelong treatment.

Tests commonly used are:

• 24-hour ambulatory blood pressure monitoring, which records your pressure through a normal working day and night and separates true hypertension from white-coat readings.
• An ECG, plus echocardiography where needed, to see whether the heart muscle has thickened or weakened.
• Blood and urine tests for kidney function, sugar, cholesterol and salts.
• An ETT (Exercise Tolerance Test) if chest pain or breathlessness on exertion suggests angina as well.

Dr. Muhammad Ali Khan, Consultant Cardiologist, offers structured hypertension management in Abbottabad, so that treatment is chosen from confirmed readings and organ assessment rather than from one alarming number.

How is high blood pressure treated?

Treatment combines lifestyle change with medicines, and the two work together rather than compete. European Society of Cardiology guidelines recommend lowering pressure to an agreed target, most often below about 140/90 mmHg in clinic, and lower still for many patients who tolerate treatment well.

The common medicine groups are:

• ACE inhibitors or ARBs, which relax arteries and protect the kidneys. Particularly useful alongside diabetes.
• Calcium channel blockers, which widen the arteries. Ankle swelling is their usual side effect.
• Thiazide-type diuretics, which remove extra salt and water.
• Other agents, including beta-blockers, added when there is another reason such as heart failure or a rhythm problem.

Modern practice often uses two medicines at low dose instead of one at high dose, because side effects rise faster than benefit as the dose climbs. Most first-line tablets are available as affordable generics in Pakistan.

How do you live with high blood pressure?

Live normally, but measure regularly and take the numbers seriously. Blood pressure control is a habit rather than an event. The tablets work only on the days you take them, and the diet works only if it is the way your household actually cooks.

Practical steps that fit local kitchens:

• Cook with measured salt, and take the salt shaker off the table.
• Treat achar, chatni, papar, namkeen and packaged snacks as occasional items rather than daily ones.
• Build flavour with lemon, garlic, ginger, green chilli, tomato and fresh coriander instead of more salt.
• Cut back on ghee-heavy and deep-fried dishes and increase vegetables, daal, fruit and whole grains. Our guide to a lower-salt Pakistani diet has practical swaps.
• Walk briskly for about 30 minutes most days. Abbottabad's climate suits a daily walk.
• Stop smoking and naswar completely.
• Take every tablet daily, at the same time, even when you feel perfectly well.
• Keep follow-up appointments so doses can be adjusted and kidney tests repeated.

Ask before using salt substitutes, because potassium-based products are unsafe for some people with kidney disease. And tell your doctor about every herbal or over-the-counter product you use. The honest list is what keeps your treatment safe.
