An Asian woman is using a blood pressure monitor to check her blood pressure at home.
Hypertension, also known as high blood pressure, is a common chronic disease among modern urban populations. As it often develops without obvious warning signs in the early stages, it is widely known as the "silent killer" in the medical field1. Many patients only discover that their blood pressure has exceeded healthy levels after experiencing serious complications such as stroke or heart failure. Apart from affecting health, long-term medical expenses arising from hypertension management and related complications may also place a significant financial burden on families. Early health planning, medical protection arrangements and appropriate lifestyle adjustments can help individuals better manage this chronic condition.

Understanding the "Silent Killer": Definition of Hypertension and the Situation in Hong Kong

What Is Blood Pressure? Understanding Systolic and Diastolic Pressure

To understand hypertension, imagine the human cardiovascular system as the water supply system found in every household. The heart works like a pump, while blood vessels act like pipes. Blood pressure refers to the force exerted by circulating blood against the walls of blood vessels.1
 
  • Systolic blood pressure (upper blood pressure reading): The pressure exerted on blood vessel walls when the heart contracts and pumps blood throughout the body.1
  • Diastolic blood pressure (lower blood pressure reading): The pressure exerted on blood vessel walls when the heart relaxes and prepares for the next contraction.1
 
If a water pump continuously operates under excessive pressure, the walls of the pipes may gradually weaken or even rupture due to prolonged stress. Similarly, persistently high blood pressure can cause irreversible damage to blood vessels and organs throughout the body.

Hong Kong Blood Pressure Standards: Which Category Do You Fall Into?

According to guidelines from the Hong Kong Department of Health, blood pressure measurements taken when adults are at rest can serve as an important indicator for assessing cardiovascular health. Adults are considered to have hypertension if their systolic blood pressure remains at 140 mmHg or above, or if their diastolic blood pressure remains at 90 mmHg or above.1
 
In addition, individuals with blood pressure readings between 120–139 / 80–89 mmHg are classified as having "prehypertension".1 Although this level does not meet the diagnostic criteria for hypertension, it serves as an important health warning. Individuals in this range should pay closer attention to their blood pressure and adopt healthier lifestyle habits early to reduce the risk of progression.

Hong Kong Statistics: Why Should Older Adults Pay More Attention?

The prevalence of hypertension among people aged 15 to 84 in Hong Kong is approximately 29.5%,2 meaning that around one in every three adults may be affected. The proportion of people with hypertension also increases significantly with age.2 Regular blood pressure monitoring can help middle-aged and older adults identify potential issues earlier and reduce the risk of hypertension-related complications.

High Blood Pressure Symptoms and Causes: Are 90% of Cases Unexplained?

Common Warning Signs of Hypertension: Not Just Dizziness and Headaches

The major concern with hypertension is that it often causes no obvious symptoms during the early stages, while silently increasing the risk of cardiovascular diseases and other serious health problems. Many people may live with high blood pressure for years without realising it. However, when blood pressure rises to dangerously high levels, some individuals may experience the following warning symptoms 2:
 
  • Persistent dizziness or headaches
  • Blurred vision
  • Unexplained fatigue or shortness of breath
  • Palpitations or an unusually rapid heartbeat

Differences Between Primary and Secondary Hypertension

From a medical perspective, hypertension can generally be divided into two main categories 3：
 
  1. Primary hypertension: Primary hypertension accounts for around 90% of all cases. It usually does not have a single identifiable cause and is commonly associated with factors such as genetics, ageing and unhealthy lifestyle habits, including excessive salt intake and insufficient physical activity.
  2. Secondary hypertension: Secondary hypertension accounts for a smaller proportion of cases. This type of high blood pressure is caused by underlying medical conditions, such as chronic kidney disease or endocrine disorders (for example, thyroid problems). If the underlying cause is properly treated or controlled, blood pressure may improve, depending on a doctor's evaluation of the specific case.

Controllable and Uncontrollable Risk Factors

There are various risk factors associated with hypertension4, which can generally be divided into uncontrollable and controllable factors.
 
  • Uncontrollable factors: Increasing age, family history of hypertension
  • Controllable factors: Excessive salt intake (high sodium consumption), lack of regular exercise, obesity, particularly central obesity, long-term stress, smoking and alcohol consumption habits
 
Understanding the risk factors of hypertension can help individuals make timely lifestyle adjustments and better manage their overall health. At the same time, understanding different medical protection and critical illness protection options can also serve as part of long-term personal and family health planning.

Complications of Hypertension: Long-Term Impact on the Body

If hypertension is not properly managed over the long term, it can place continuous pressure on blood vessels and vital organs. Over time, this may lead to accumulated damage and increase the risk of various serious or potentially life-threatening complications5.

Cardiovascular Risks: Stroke and Heart Failure

Persistently high blood pressure can accelerate the hardening of arteries5, causing blood vessels to become narrower and lose their elasticity.
 
  • Impact on the brain: Hardening of blood vessels can increase the risk of blood vessel rupture or blockage in the brain, leading to stroke3. For severe cases of ischaemic stroke, patients may require long-term physical rehabilitation and round-the-clock care. The associated rehabilitation expenses and private hospital costs may also place significant financial pressure on families. 
  • Impact on the heart: When blood pressure remains elevated over a prolonged period, the heart must work harder to pump blood throughout the body5. Over time, this may cause enlargement of the heart muscle (ventricular hypertrophy) and increase the risk of myocardial infarction and heart failure.

The Two-Way Relationship Between Hypertension and Chronic Kidney Disease

Hypertension can contribute to kidney disease, while kidney disease can in turn worsen high blood pressure 6. High blood pressure can damage the tiny blood vessels inside the kidneys, reducing their ability to filter waste products from the body. Meanwhile, declining kidney function may cause excess fluid and salt to accumulate, further increasing blood pressure.
 
When kidney disease progresses to end-stage kidney failure, patients generally require long-term haemodialysis (kidney dialysis) treatment. In Hong Kong private healthcare facilities, outpatient haemodialysis or online haemodiafiltration may cost approximately HK$3,100 to HK$5,456 per session, excluding doctor's fees and medication costs. Actual treatment expenses may vary depending on the frequency of dialysis, treatment arrangements, doctor's fees, medication costs and individual health conditions 7. In the long term, these costs may create significant challenges for both quality of life and financial planning.

Daily Management Tips: How to Control High Blood Pressure Effectively?

Lifestyle adjustments, including dietary changes, regular exercise, smoking cessation, limiting alcohol consumption and regular blood pressure monitoring, can help prevent and manage hypertension. The following are some commonly recommended approaches:

Dietary Management: Reducing Sodium Intake, Increasing Potassium and Following the DASH Diet

Hong Kong residents dine out frequently, which may result in excessive salt (sodium) intake. Individuals can consider following the principles of the internationally recognised DASH Diet8. 
 
  1. Control salt intake: Daily salt intake should be limited to approximately 1 teaspoon (around 5-6 grams). When purchasing food products, develop the habit of checking nutrition labels and avoid hidden high-sodium foods, such as processed meat, instant noodles and canned sauces.
  2. Increase potassium intake: Consume more potassium-rich vegetables and fruits, such as spinach and bananas, which may help the body remove excess sodium.
  3. Make balanced food choices: Replace refined carbohydrates with whole grains, and choose low-fat dairy products and high-quality lean protein sources such as white meat.

Building a Home Monitoring Habit: Understanding the "722" Blood Pressure Monitoring Method

Blood pressure measured at clinics may occasionally appear higher due to stress or anxiety, a phenomenon known as white coat hypertension. To obtain more accurate readings for healthcare professionals to evaluate, individuals can practise the "722 method" at home 9.
 
  • 7: Measure blood pressure continuously for seven days.
  • 2: Measure twice a day (once in the morning and once in the evening).
  • 2: Take two readings each time (approximately one minute apart) and calculate the average value.

Protection Planning: Reducing the Financial Pressure Associated with Chronic Conditions

People with hypertension often require long-term medication and regular medical follow-ups. If complications such as stroke or kidney disease occur, the required specialist treatments and long-term care may involve substantial ongoing medical expenses.
 
As part of personal financial planning, individuals may consider different medical protection or critical illness protection options based on their personal needs and family budget. These solutions may help individuals manage the potentially substantial medical expenses associated with complications more flexibly. Medical insurance plans, such as Voluntary Health Insurance Scheme (VHIS) plans, may generally provide coverage for eligible outpatient surgical procedures and hospitalisation expenses, while critical illness protection may provide a lump-sum cash benefit upon diagnosis of a specified critical illness. The actual scope of coverage and benefit amount are subject to the policy terms and conditions, coverage provisions, and claim assessment results.

About Hypertension FAQs

It depends on the individual situation. First, it is important to determine whether the condition is primary or secondary hypertension. For individuals with early-stage primary hypertension, improving lifestyle habits through weight management, a low-sodium diet and regular exercise may allow some patients to gradually reduce medication dosage or even stop taking medication under the guidance of their doctor.1 However, patients should never stop medication without medical advice.

This may be related to "white coat hypertension"9, where patients experience temporary increases in blood pressure due to nervousness or stress when visiting a clinic or interacting with healthcare professionals. Individuals can try the "722 method" (measuring for seven consecutive days, twice daily, with two readings each time) and provide more stable home measurements as a reference for their doctor's assessment.

Individuals can explore relevant options based on their personal circumstances. Generally, insurance companies assess applications according to factors such as blood pressure control, medication records and overall health condition. Applicants may consult professional insurance advisers and understand suitable protection arrangements through pre-underwriting procedures or preliminary assessments.

No. In recent years, hypertension has become increasingly common among younger populations2. Long-term obesity, high work-related stress, insufficient physical activity and a diet high in salt are among the factors contributing to hypertension risk among younger individuals. Regardless of age, regular blood pressure monitoring and maintaining a healthy body mass index (BMI) are important for preventing cardiovascular diseases.
