How Can I Prevent a Stroke? Heart-Healthy Habits for Singaporeans
Key Takeaways:
- A clearer answer to “how can I prevent a stroke?” starts with knowing your risk factors.
- Stroke risk factors include both non-modifiable risks, such as age and family history, and modifiable risks, such as high blood pressure, diabetes, high blood cholesterol, smoking, obesity and physical inactivity.
- Managing blood pressure, blood sugar and blood cholesterol through regular screening, medical advice and daily lifestyle habits can help reduce stroke risk over time.
- S.M.A.R.T. living offers a practical framework for building healthier choices into everyday life.
Introduction
A stroke occurs when part of the brain is damaged due to an interruption of its blood supply. This can happen when a blood vessel supplying the brain is blocked, causing an ischaemic stroke, or when a blood vessel bursts, resulting in a haemorrhagic stroke.
Depending on the area of the brain affected, a stroke can lead to lasting disabilities. These may include weakness or paralysis on one side of the body, difficulty speaking, problems processing information or loss of independence that requires long-term care.
Stroke is a leading cause of disability and death in Singapore. With an ageing population, the number of stroke cases is rising, and 1 in 4 people is likely to suffer a stroke in their lifetime. This makes stroke awareness important not only for older adults, but also for families, caregivers and the wider community.
The good news is that most strokes can be prevented. While age and family history cannot be changed, many other risks can be managed through lifestyle changes, medication adherence, and regular screening. If you have ever wondered, “How can I prevent a stroke?”, the answer begins with understanding your risk factors and taking practical steps early.
Understanding Stroke Risk Factors
Before delving into how you can prevent a stroke, it is essential to assess the risk factors. These factors can be broadly divided into non-modifiable and modifiable risks.
Non-modifiable risk factors are those that cannot be changed. These include older age and a family history of stroke. Although these risks cannot be removed, knowing about them allows individuals to monitor their health earlier and more closely.
On the other hand, modifiable risk factors are those that can be managed or reduced. These include high blood pressure, diabetes, high blood cholesterol, smoking, obesity, a sedentary lifestyle, excess salt intake and excess alcohol intake.
What to Take Note of
Managing these factors may help reduce stroke risk. In many cases, stroke prevention is not about one major change, but about several consistent habits that support healthier blood vessels, better circulation and improved cardiovascular health over time.
1. Control High Blood Pressure
High blood pressure is one of the risk factors for stroke prevention. Uncontrolled hypertension can increase stroke risk significantly because it places added pressure on the blood vessels, including those supplying the brain.
High blood pressure often has no obvious symptoms, which is why regular monitoring is essential. It is vital to monitor blood pressure and treat it if it repeatedly exceeds the recommended range. For higher-risk individuals, such as those with diabetes, a reading of 130/85 mmHg or higher may indicate the need for closer medical management.
2. Control Blood Sugar Levels (If You Have Diabetes)
Diabetes is another key risk factor. Adults with diabetes are 1.5 times more likely to suffer a stroke and twice as likely to die from heart disease or stroke compared to those without diabetes. This is because high blood sugar can damage blood vessels over time, increasing the risk of circulatory problems affecting the heart, brain, kidneys and other organs.
For people with diabetes, keeping blood sugar levels under control is a key part of stroke prevention. Understanding what a healthy blood sugar range looks like can also help individuals recognise when their readings may need closer medical review.
3. Control High Blood Cholesterol Levels
High blood cholesterol can increase stroke risk by contributing to fatty deposits in the arteries. Over time, these deposits can narrow blood vessels and reduce blood flow to the brain. This raises the risk of ischaemic stroke.
Cholesterol levels are not always obvious from how a person feels. Regular screening is therefore important, especially for adults with other risk factors such as diabetes, high blood pressure, obesity or a family history of cardiovascular disease.
Stay a Step Ahead with S.M.A.R.T. Living
A practical answer to “how can I prevent a stroke?” begins with S.M.A.R.T. living. This simple framework highlights everyday habits that can help reduce key risk factors, from avoiding smoking/vaping and making healthier food choices to staying active.
S – Smoke-Free Life
Smoking increases stroke risk by about 1.5 to 2.5 times. Heavy smoking may raise the likelihood of stroke further. This is because smoking damages blood vessels, affects blood pressure and increases the risk of clot formation.
The risk can be reduced when a person stops smoking. Over time, the stroke risk of a former smoker can become closer to that of a non-smoker. Seeking medical advice and support can improve the chances of quitting successfully.
A smoke-free life also supports overall heart and lung health. For households, it helps reduce exposure to second-hand smoke, which can also affect the health of family members.
M – Meals That Are Healthy
Diet plays a part in stroke prevention because unhealthy eating patterns can contribute to high blood pressure, diabetes and high blood cholesterol.
Healthy dietary practices include reducing salt intake, limiting alcohol consumption, lowering sugar intake, choosing foods high in fibre and eating more vegetables and whole grains. Reducing intake of saturated fats and cholesterol-rich foods can also support better heart health.
In Singapore, this may mean being mindful of hidden salt and fat in everyday meals, sauces, gravies, processed foods and deep-fried dishes. Small but consistent changes can help support healthier blood pressure, blood cholesterol and weight management over time.
A – Active Lifestyle
A sedentary lifestyle increases stroke risk. Regular physical activity helps support blood pressure, blood cholesterol, diabetes control, obesity management and overall cardiovascular health.
Adults should aim for at least 150 to 300 minutes of moderate-intensity aerobic physical activity each week. This can include brisk walking, cycling, swimming or other activities that raise the heart rate while still allowing conversation.
The most sustainable exercise routine is one that fits into daily life. For some people, this may mean walking after meals. For others, it may mean joining a community exercise class, taking the stairs more often or setting aside time for weekend activities.
Healthy weight management also matters. Obesity is associated with high blood pressure, diabetes and high blood cholesterol. Abdominal fat accumulation is closely linked to increased health risks, making weight control a key part of prevention.
R – Regular Health Screening
Many stroke risk factors are silent conditions. High blood pressure, high blood cholesterol and diabetes may not cause obvious symptoms in the early stages. Regular screening allows these conditions to be detected earlier and managed before complications develop.
Recommended screening includes blood pressure and obesity checks from age 18 onward, every 2 years or more frequently if advised. Diabetes and cholesterol screening is generally recommended from age 40 onward, once every 3 years or more frequently, depending on individual risk.
Regular health screening is not only useful when symptoms appear. It is a preventive step that gives individuals a clearer view of their health. Detecting problems early allows timely lifestyle changes, medical advice and treatment where needed.
Blood pressure reference points can also guide further review. Blood pressure should be treated if it is repeatedly above 140/90 mmHg. For individuals with diabetes, the target blood pressure should generally be below 130/85 mmHg, per medical guidance.
T – Take Prescribed Medications
If a person has been diagnosed with high blood pressure, diabetes or high blood cholesterol, taking medication as prescribed also helps prevent stroke. These conditions often require consistent management to keep risk factors under control.
Medication should not be stopped without medical advice, even if readings improve or there are no obvious symptoms. Silent conditions can still increase stroke risk over time, so ongoing treatment and regular follow-up remain important.
Cholesterol-lowering medication such as statins may be prescribed to reduce stroke and heart disease risk. Prescription diabetes medication is also crucial for blood sugar control. For individuals with multiple risk factors, following the treatment plan can make a meaningful difference to long-term health.
Building a Heart-Healthy Singapore
Understanding how to prevent a stroke empowers individuals to take control of their health before complications arise. Managing blood pressure, maintaining a healthy weight, adopting a balanced diet, staying active and attending regular screenings can all help reduce risk.
Prevention is also part of a wider public health effort. Stroke and heart disease share several common risk factors, including high blood pressure, diabetes, high blood cholesterol, smoking and obesity. This is why heart health education is closely connected to stroke awareness.
The Singapore Heart Foundation supports stroke and heart disease prevention through evidence-based health education, community outreach initiatives and structured wellness programmes. These efforts help Singaporeans better understand their risks, take preventive action and build greater confidence in protecting their cardiovascular health.
