The Dangers Of Neglecting Hypertension In Malaysia The Silent Killer Among Us

---

 
HYPERTENSION, or high blood pressure, is a chronic condition where the blood force against artery walls is consistently high. Known as the “silent killer”, it often has few or no symptoms, making regular monitoring essential.
Hypertension is defined as persistent elevation of blood pressure at or above 140/90mmHg, confirmed by measurements taken on at least two to three separate occasions.
However, blood pressure readings in the range of 130-139mmHg systolic and 85-89mmHg diastolic are already considered “at-risk”.
People with blood pressure within this range should monitor their blood pressure closely and make lifestyle changes to help lower their blood pressure.
According to the National Health and Morbidity Survey 2023, hypertension affects 29.2% or nearly one in three adults in Malaysia.
Of this figure, 11.9% do not actually know that they have hypertension and alarmingly, the highest proportion of those who are unaware falls within the age of 18-39, indicating a rising concern in younger populations.
Despite these significant risks, many Malaysians remain oblivious to their hypertensive status, often due to the condition’s asymptomatic nature in its early stages.

A prevalent myth is that hypertension is only a concern for the elderly, which is a dangerous misconception, with many younger people believing that they are not at risk, leading to neglect and late diagnosis.
The subtle symptoms and serious complications
There is often no sign or symptom in hypertension, making regular screenings essential. When symptoms do occur, hypertension may have already been present for some time.
These symptoms may include headaches, dizziness, shortness of breath, chest pain and nosebleeds.
If left untreated, hypertension can lead to severe and potentially life-threatening complications, including heart attack, heart failure, irregular heart rhythm, stroke, kidney failure and vision loss.
“People should minimally get their blood pressure checked at least once a year as part of their annual health screening,” said Sunway Medical Centre consultant general physician (Internal Medicine) Dr Jolene See Su Chen.
“Blood pressure should also be checked during clinic encounters when visiting the doctor for other health concerns.
“Those with a family history of hypertension or heart disease should monitor their blood pressure regularly at home. Early detection is key to managing the condition effectively.”
Lifestyle and dietary habits: Culprits behind the numbers
According to Dr See, many Malaysians consume diets high in salt and fat, and low in essential nutrients. Combined with a lack of physical activity and high-stress work environments, this is a perfect storm for developing high blood pressure.
As such, people are advised to control their daily sodium intake, keeping it below 2,000mg a day, which is equivalent to approximately one teaspoonful a day.

“The DASH diet focuses on increasing intake of vegetables, fruits, whole grains, and lean proteins (from lean meat, poultry or fish). It is also important to choose foods that are low in saturated and trans-fat, which are commonly found in processed food.”
Managing hypertension: Lifestyle changes and medication
Managing and preventing hypertension involves proactive steps. “Eating a balanced diet rich in fruits and vegetables, reducing salt and alcohol intake, not smoking, keeping active with regular exercises and maintaining a healthy weight are key preventive measures,” said Dr See.
Some general guidelines for maintaining a healthy weight include:
Body Mass Index (BMI): Aim for a BMI between 18.5 and 22.9, based on the Malaysia CPG Management of Obesity 2023.Waist circumference: Men should aim for a waist circumference of less than 90cm and women less than 80cm, based on the Malaysia CPG Management of Obesity 2023.Weight loss: Even a modest weight loss of 5-10% of your current weight can significantly improve blood pressure and overall health.Dr See further emphasised the importance of adhering to prescribed treatments for hypertension, advising newly diagnosed patients to take their condition seriously, make necessary lifestyle changes, and follow their doctor’s advice without adjusting medication dosages on their own.
She also addressed a common myth that taking long-term medication might harm their kidneys and lead to kidney failure.
She highlighted that this mindset is dangerous, as all medications are scientifically tested and prescribed at safe dosages under the supervision of the patients’ doctor.
“In contrast, untreated hypertension can severely damage blood vessels supplying the kidneys, leading to kidney failure and damaging other vital organs, much more quickly and severely,” she added. – Focus Malaysia
