29 October is World Stroke Day, a fitting moment to talk about the condition most closely tied to stroke: high blood pressure, known in Malaysia as darah tinggi. Many people in Ipoh only find out they have it at a routine check, or after a stroke or heart attack, because it usually causes no symptoms at all.
So when people search “how to know if I have high blood pressure”, the honest answer is that you usually cannot tell by how you feel. The way to know is a measurement by a doctor or nurse. This article explains why darah tinggi is often silent, its common causes and long-term risks, everyday habits that help, and the warning signs that mean calling 999. It is general information only.
Tanda Darah Tinggi (Signs of High Blood Pressure): Why It Is Often Silent
High blood pressure, or hypertension, means the force of blood against the artery walls stays higher than it should over a long period. As WHO and the NHS both note, most people with it have no symptoms. There is no reliable tanda darah tinggi you can feel, which is why it is often called a “silent killer”.
It is also common. National health surveys have found that roughly three in ten Malaysian adults have high blood pressure, and around half of them did not know. Very high blood pressure can occasionally bring signs such as a severe headache, chest pain or blurred vision. These need urgent attention, and only a doctor can assess what is causing them.
Headaches, Dizziness and Other Common Myths
Headache and dizziness are the complaints people most often link with darah tinggi, but neither can show by itself that blood pressure is high. Both have many everyday causes, such as tension, poor sleep, dehydration and eye strain, and pain or stress can push blood pressure up briefly. Only a doctor can assess what lies behind a symptom.
Two other myths worth clearing up:
- “Only older or overweight people get it.” Risk rises with age and weight, but younger and slim people can have it too.
- “A red face or a nosebleed means my pressure is up.” Neither is a reliable sign.
Punca Darah Tinggi (Causes of High Blood Pressure)
For most people there is no single cause. High blood pressure tends to develop slowly from a mix of inherited tendency and everyday habits.
Family history. A parent or sibling with darah tinggi raises your risk, although it does not make it certain.
Salt-heavy eating. Malaysian salt surveys have found that adults, on average, eat well above the amount WHO recommends. Much of it is hidden in kicap, sos tiram, sos cili, budu and ikan masin, in instant noodles, in processed foods such as sausages and keropok, and in meals eaten out most days.
Other factors. Extra weight, inactivity, smoking, regular drinking, poor sleep and long-term stress all add to the risk, and arteries stiffen with age. In a smaller number of people, another condition, such as a kidney or hormone problem, is involved; a doctor may assess this, particularly at a younger age.
Bahaya Darah Tinggi (Dangers of High Blood Pressure): Heart, Brain, Kidneys and Eyes
The harm comes from years of extra strain:
- Heart: it works harder and its muscle can thicken, raising the risk of heart attack and heart failure.
- Brain: high blood pressure is the most important modifiable risk factor for stroke.
- Kidneys: damage to their small blood vessels can reduce how well they work over time.
- Eyes: tiny vessels at the back of the eye can be damaged, which may affect vision.
High cholesterol adds to this. Raised pressure can damage the artery lining, making it easier for fatty deposits to build up and narrow the arteries. When high blood pressure, high cholesterol, diabetes and smoking occur together, the risk is far greater than with any one alone. The article on kolesterol tinggi signs and causes covers that side of the picture.
Everyday Habits and When to Ask a Doctor About a Check
Healthy habits help over months and years. They are not a quick fix and do not replace a doctor’s advice:
- Go easy on salt: ask for less kicap or sos, leave some of the soup in noodle dishes, and choose fresh food over instant and processed options.
- Fill the plate well: the Ministry of Health’s Suku-Suku Separuh guide suggests half the plate as vegetables and fruit.
- Move more: regular moderate activity, such as brisk walking on most days of the week, helps.
- Keep to a healthy weight, avoid smoking and limit alcohol.
- Look after sleep and stress. Loud snoring with pauses in breathing is worth mentioning to a doctor.
Because darah tinggi is usually silent, having your blood pressure measured by a doctor or nurse from time to time is how to know where you stand, even when you feel well. Adults of any age can ask a doctor about a check, and it is especially sensible if it runs in your family, you are getting older, carry extra weight, smoke, have diabetes or high cholesterol, or were told before that your pressure was high. A doctor can interpret any measurement and advise how often to check.

World Stroke Day: Warning Signs That Mean Call 999 Now
Call 999 or go to the nearest emergency department straight away for:
- A sudden, severe headache unlike any before
- Chest pain, or sudden breathlessness
- Face drooping, or weakness in an arm or leg
- Slurred speech
- Sudden loss of vision or sudden confusion
Do not wait to see whether these settle. In a stroke every minute counts, even if the symptoms fade.
Frequently Asked Questions
How do I know if I have high blood pressure?
Usually you cannot tell from how you feel, because high blood pressure rarely causes symptoms. The way to know is a measurement by a doctor or nurse, who can explain what it means for you.
Apa tanda tanda darah tinggi atau simptom darah tinggi? (What are the signs or symptoms of high blood pressure?)
Most people have none, which is why darah tinggi is often missed. Very high pressure can occasionally bring a severe headache, chest pain or blurred vision, which needs urgent attention. Only a doctor can assess the cause of any symptom.
Kenapa darah tinggi sakit kepala? (Why does high blood pressure cause headaches, and does it?)
Research suggests long-term high blood pressure does not usually cause headaches; tension, poor sleep and dehydration are common causes. A sudden, severe headache, however, can come with very high pressure or a stroke and needs emergency care. Only a doctor can assess what is behind a headache.
Is high blood pressure genetic?
Partly. It runs in families through inherited genes and shared habits, such as salty home cooking. A family history raises the risk without making it certain, so it is worth mentioning to a doctor.
Can high blood pressure cause a stroke?
Yes. Years of raised pressure damage the blood vessels supplying the brain, making high blood pressure the most important modifiable risk factor for stroke. Sudden face drooping, arm weakness or slurred speech means calling 999.
