Hypertension alert: Know your blood pressure, take care of your heart

Hypertension, or high blood pressure, affects over 1.28 billion people globally and is a leading cause of heart attacks, strokes, and kidney failure. Often symptomless, it's known as the 'silent killer,' silently damaging vital organs over time.
In the UAE, lifestyle factors like poor diet, stress, and physical inactivity are fuelling its rise, with nearly one in three adults affected. As we mark 20 years of World Hypertension Day, this year's theme — 'Measure Your Blood Pressure Accurately, Control It, Live Longer' — reminds us that early detection, accurate monitoring, and lifestyle changes are key to long-term heart health.
'Your plate can either protect your heart or pressure it,' says Vibha Bajpaiee, Clinical Dietician at Aster Clinic, Bur Dubai (AJMC). 'A diet low in salt, saturated fats, and processed foods, but rich in fruits, vegetables, whole grains, and potassium-rich foods, helps regulate blood pressure naturally. Avoid sugary drinks and excess caffeine. Opt for home-cooked meals with herbs instead of salt for flavour. Keep an eye on food labels — hidden sodium is common. Hydration, portion control, and mindful snacking also play key roles. Combine smart eating with regular movement, and you create a strong defence against hypertension. Remember, what you eat today can shape your heart health tomorrow.'
Know your numbers: Why regular BP checks should be your daily habit
Dr Heba Tag Eldin, Specialist Cardiology at Aster Clinic, Halwan (Sharjah), says: 'High blood pressure rarely shows symptoms, which is why regular monitoring is crucial.' 'Measuring your blood pressure accurately at home or in a clinic helps detect abnormalities early, often before complications develop. Aim to check at the same time each day, in a relaxed state, and use a validated device. Record your readings to spot trends. Knowing your numbers empowers you to take proactive steps — whether through lifestyle changes or medication. Don't wait for symptoms; prevention begins with awareness. Early action based on accurate readings can help you avoid long-term damage to your heart, brain, and kidneys.'
From salt to stress: Blueprint for a heart-healthy lifestyle
'Managing high blood pressure begins with sustainable lifestyle changes,' says Dr Ashik Sasidharan, Specialist Cardiology at Aster Clinic, Al Qusais (Damascus St.). 'Reduce salt intake to less than 5g a day, maintain a healthy weight, and exercise regularly — aim for at least 30 minutes of moderate activity most days. Limit alcohol, quit smoking, and manage stress through mindfulness, breathing exercises, or hobbies you enjoy. Sleep is equally important; poor rest can increase blood pressure. Monitor your intake of caffeine and processed foods, which can trigger spikes. Lifestyle choices may seem small, but collectively, they can significantly lower blood pressure, improve heart function, and reduce your need for long-term medication.'
The kidney connection: How high blood pressure wreaks silent havoc
'Hypertension is a major contributor to chronic kidney disease, often causing silent, progressive damage over time,' says Dr Azeem Ahamed, Specialist Nephrology at Aster Clinic, Bur Dubai (AJMC), and Aster Cedars Hospital & Clinic, Jebel Ali. 'When blood pressure remains elevated, it puts extra strain on the delicate vessels in the kidneys, reducing their ability to filter waste effectively. Over time, this can lead to kidney failure. Regular kidney function tests and urine checks can help detect early damage. Managing your blood pressure through diet, lifestyle, and medication is essential to protect kidney health. Hydrate well, limit salt and processed foods, and avoid overuse of painkillers, which can worsen kidney function. Healthy blood pressure supports healthy kidneys — for life.'
Pressure builds silently: Early signs you should never ignore
Dr Sachin Upadhyaya, Specialist Cardiology at Aster Hospital, Mankhool, says: 'Though hypertension is often symptomless, some people may experience subtle signs like frequent headaches, nosebleeds, blurred vision, chest discomfort, or shortness of breath.' He further explains 'These should not be dismissed. If you're at risk due to family history, obesity, stress, or poor lifestyle habits, regular screening becomes even more essential. Left unmanaged, high blood pressure can silently damage arteries and vital organs. According to the latest 2024 ESC guidelines, even patients with BP above 120/70 mmHg should undergo risk evaluation and begin treatment if found high-risk. If you notice these early indicators, seek medical evaluation immediately. It's better to investigate mild symptoms than wait for a crisis. Timely detection and early intervention can prevent irreversible heart, brain, or kidney complications.'
Prepping the heart: Why controlled BP is crucial before surgery
Dr Anil P Kumar, Specialist Interventional Cardiology at Aster Hospital, Qusais, says: 'For patients undergoing cardiac or any major surgery, optimal blood pressure control is non-negotiable.' 'Uncontrolled hypertension increases the risk of bleeding, stroke, heart attack, and complications during anaesthesia. Before surgery, a thorough assessment — including blood pressure monitoring—is performed to stabilise the patient. Medications may need adjusting, and lifestyle changes may be recommended in the lead-up to the procedure. Preoperative control of blood pressure improves surgical outcomes, reduces ICU stays, and speeds up recovery. If you're scheduled for surgery, work closely with your healthcare provider to bring your blood pressure within target range well before your operation.'
Inside the OR: How surgeons handle hypertension-compromised hearts
'Operating on a heart burdened by years of high blood pressure poses unique challenges,' says Dr Debabrata Dash, Consultant Interventional Cardiology at Aster Hospital, Mankhool. 'Chronic hypertension leads to thickened heart walls, stiff arteries, and a higher risk of bleeding during surgery. Surgeons must anticipate complications like arrhythmias or reduced heart function. Intraoperative blood pressure must be managed meticulously to avoid sudden drops or spikes. Every second in the operating room is calculated, and surgical plans are customised for hypertensive patients. Timely surgical intervention, supported by a multidisciplinary team, helps stabilise cardiac function and prevent catastrophic outcomes. Managing hypertension before and after surgery is vital to long-term recovery.'
Post-op and beyond: Managing hypertension after cardiac surgery
Dr Srinivasan Kandasamy, Specialist Cardiology at Aster Hospital, Qusais, says: 'Recovery from cardiac surgery doesn't end in the hospital — it extends into daily life.'
'Managing blood pressure post-surgery is essential to protect your surgical outcomes and prevent recurrence. Follow your medication schedule strictly, attend follow-up appointments, and maintain a low-sodium, heart-healthy diet. Gradually return to physical activity under medical guidance. Track your blood pressure regularly and watch for signs like swelling, fatigue, or dizziness. Mental well-being matters too — address anxiety or depression, which can affect your BP. With consistent effort, many patients achieve better blood pressure control post-surgery than before. Long-term success lies in disciplined, proactive care.'
