If I were to ask readers what they think is one of the biggest health threats facing Malaysians today, many might say cancer or heart disease. Others may think of diabetes.
All of these are serious conditions, but there is one health problem that often sits quietly in the background, causing damage for years before anyone even realises it.
High blood pressure.
As a pharmacist, I have spent over 30 years talking to patients about their medicines and their health. One conversation has stayed remarkably consistent throughout my career.
“I feel absolutely fine.”
It’s something I’ve heard countless times from people who have just been told they have high blood pressure.
The problem is that high blood pressure usually doesn’t make you feel unwell.
That is why it is often called the “silent killer.” You can have it for years without any obvious symptoms while, quietly and gradually, it damages your blood vessels, heart, kidneys and even your eyesight.
Many people believe they would know if their blood pressure was high because they would get headaches, feel dizzy or have nosebleeds.
In reality, most people experience none of these symptoms.
The first sign can sometimes be a heart attack or a stroke.
That is why regular blood pressure checks are so important.
So, what exactly is blood pressure?
Think of your blood vessels as a network of pipes carrying blood around your body. Your heart acts as the pump. Blood pressure is simply the force of the blood pushing against the walls of those blood vessels as your heart pumps.
A certain amount of pressure is perfectly normal and necessary. The problem begins when that pressure stays too high for too long.
Imagine turning a garden hose on full power all day, every day. Eventually, the hose begins to wear. The same thing can happen to your blood vessels.
Over time, high blood pressure makes the heart work harder than it should. It also increases the risk of strokes, heart attacks, kidney disease and other serious health problems.
The worrying thing is that many of the risk factors are part of modern life.
We eat too much salt without even realising it. Many processed foods, instant noodles, sauces and takeaway meals contain surprisingly high amounts.
We sit more than previous generations. Office jobs, television, computers and smartphones all mean we spend less time moving.
Being overweight also increases the strain on the heart, and Malaysia continues to struggle with one of the highest obesity rates in Southeast Asia.
Stress may also play a role. While stress alone doesn’t usually cause permanent high blood pressure, it can certainly contribute to unhealthy habits such as overeating, smoking, drinking too much alcohol or avoiding exercise.
The good news is that high blood pressure is one of the most manageable health conditions.
Small changes really do make a difference.
Walking for 30 minutes most days of the week is a great place to start. You don’t need to become a marathon runner or spend hours in the gym. Simply being more active benefits both your heart and your overall wellbeing.
Eating more fresh fruit and vegetables, reducing salt, cutting back on sugary drinks and choosing home-cooked meals more often can also have a positive effect.
If you smoke, stopping is one of the best gifts you can give your heart.
Sometimes, however, lifestyle changes alone are not enough.
Some people will need medication, and there is absolutely no shame in that.
One of the biggest misconceptions I come across is people stopping their tablets because they feel better.
The medicine hasn’t cured the condition—it is controlling it.
Stopping treatment without speaking to your doctor can allow blood pressure to rise again, increasing the risk of complications.
I’ve also met people who are worried about taking medication for life.
My advice is always the same.
Don’t think about the tablet.
Think about what the tablet is preventing.
A small tablet taken once a day may help prevent a stroke, heart attack or kidney failure years down the line. That’s a worthwhile investment in your future health.
Finally, I would encourage everyone over the age of 40—or younger if there is a family history of high blood pressure, diabetes or heart disease—to have their blood pressure checked regularly. It only takes a few minutes and could quite literally save your life.
As I mentioned in my introduction to this column, my aim is to make health easy to understand and to help you make informed decisions without unnecessary medical jargon or frightening statistics.
Health doesn’t have to be complicated.
Sometimes the smallest changes can make the biggest difference.
If there’s a health topic you’d like me to cover in a future column, please leave a comment below. Whether it’s cholesterol, arthritis, eye health, dementia, medicines, healthy ageing or another everyday health concern, I’d love to hear your suggestions.
After all, this column isn’t just about sharing my experience as a pharmacist—it’s about having a conversation with you.
Until next week, take care of yourself… because your health is something worth investing in every single day.
