Strokes Uncovered: How to Spot the Signs and Protect Your Health

A stroke is one of those moments when every second truly counts. It happens without warning, when the flow of blood to part of the brain is suddenly cut off or drastically reduced. Without that steady supply of oxygen and nutrients, the brain can’t function as it should.

In those first few minutes, brain cells begin to die, and the window to act becomes frighteningly small. That’s why recognising what causes strokes, knowing the warning signs and understanding how to prevent them can make an enormous difference. It gives people the chance to protect themselves and their loved ones, and in many cases, it can change the outcome entirely.

Causes of Stroke

Doctors tend to think about strokes in two broad categories. The first is an ischaemic stroke, which happens when blood struggles to reach part of the brain. The second is a haemorrhagic stroke, which occurs when a blood vessel bursts and causes bleeding. Although they share a name, these two events unfold in very different ways and for very different reasons.

Ischaemic stroke

Ischaemic strokes account for more than 80% of all strokes, making them by far the most common type. They happen when a blood clot suddenly blocks or squeezes an artery that supplies the brain, cutting off the oxygen it relies on. These clots don’t appear out of nowhere; a range of underlying conditions can set the stage for them, including:

Atherosclerosis

Fatty deposits, called plaques, build up inside artery walls. When a plaque ruptures, a clot can form and block blood flow.

Cardioembolism

A clot forms in the heart and travels to the brain. Atrial fibrillation, an irregular heartbeat, often leads to these cardioembolic strokes.

Small vessel disease

Sometimes called a lacunar stroke, this occurs when small blood vessels deep within the brain become blocked.

Haemorrhagic stroke

A haemorrhagic stroke happens when a blood vessel inside the brain suddenly bursts, allowing blood to spill into the surrounding tissue. It is less common than other types of stroke, making up roughly 15% of all cases, but it can be particularly severe. Several factors can lead to this kind of stroke, including:

Hypertension

Long-standing high blood pressure can weaken blood vessel walls and make them more likely to rupture.

Aneurysm

A weakened, bulging section of a blood vessel can burst and cause bleeding.

Arteriovenous malformation

This condition is present at birth and involves an abnormal connection between arteries and veins in the brain. These vessels can rupture and cause bleeding.

Trauma

A head injury can damage blood vessels and lead to bleeding in the brain.

Symptoms of Stroke

Recognising stroke symptoms quickly can save a life, limit long-term damage, and give someone the best chance at recovery. In those first urgent moments, the acronym FAST is a simple way to remember the most common warning signs; a small word that could make an enormous difference.

Face drooping

One side of the face may droop or feel numb. Ask the person to smile and check if the smile looks uneven.

Arm weakness

One arm may feel weak or numb. Ask the person to raise both arms and see if one drifts downward.

Speech difficulty

Speech may sound slurred or unclear. Ask the person to repeat a simple sentence.

Time to call emergency services

If any of these signs appear, call emergency services straight away.

Other symptoms can also signal a stroke, including:

• Sudden confusion or trouble understanding speech

• Sudden vision problems in one or both eyes

• Sudden trouble walking, dizziness or loss of coordination

• Sudden severe headache with no clear cause

Effective Prevention Strategies

Preventing a stroke isn’t just about numbers on a chart; it’s about taking small, meaningful steps every day to protect your health. By actively managing risk factors and following healthy habits, you can lower your chances of developing high blood pressure, diabetes, or high cholesterol, and also make life easier for those already living with these conditions. Every walk, balanced meal, and mindful choice counts towards keeping your heart and brain healthy.

Attend regular medical check ups

Routine health reviews are important opportunities to catch small changes before they become big problems. Keeping an eye on your blood pressure, blood sugar, and cholesterol gives you a clearer picture of your overall health. If you’re managing a long-term condition, taking your prescribed medicines exactly as your doctor recommends can make a real difference in keeping you well and active.

Choose a balanced and nutritious diet

Fill your plate with fresh fruits and vegetables, hearty wholegrains, and lean proteins like fish, poultry, beans, and nuts. Try to ease back on foods high in saturated and trans fats, cholesterol, and salt, and let processed snacks and sugary drinks be occasional treats rather than everyday staples. Your body will thank you with more energy, better health, and a happier heart.

Stay physically active

Regular exercise is a gift to both your body and mind. Moving your body helps keep your weight in check, eases stress, and even lowers blood pressure. Aim for at least 150 minutes of activity each week; think of it as carving out time for yourself. Whether it’s a brisk walk in the fresh air, a refreshing swim, a cycling adventure, or a gentle jog, find the movement that makes you feel alive and enjoy the journey as much as the destination.

Maintain a healthy weight

Carrying extra weight can quietly put your heart, blood sugar, and cholesterol at risk. Taking care of your body doesn’t have to be complicated; focus on nourishing meals, moving in ways you enjoy, and setting goals that feel achievable. Small, consistent steps can make a big difference for your health and energy.

Limit alcohol intake

Enjoying a drink now and then can be part of life, but too much alcohol can quietly raise your blood pressure and increase your risk of stroke. Health guidelines recommend no more than one drink a day for women and two for men. Even small changes, like swapping in a refreshing nonalcoholic alternative, can make a meaningful difference for your heart and overall wellbeing.

Stop smoking

Smoking takes a serious toll on your blood vessels and sharply raises your risk of stroke. The good news is that quitting can help your blood vessels heal and significantly reduce that long-term risk. Many people find that having a plan makes all the difference; setting a clear quit date, reaching out for counselling or support groups, and using tools like nicotine replacement products or medications. Every small step you take brings you closer to a healthier, smoke-free life.

Monitor and treat atrial fibrillation

Atrial fibrillation, a common irregular heartbeat, may feel like your heart is racing, fluttering, or skipping beats, and it can quietly increase your risk of stroke by allowing blood clots to form. Fortunately, regular checkups, medicines to keep your heart rate and rhythm in balance, and sometimes blood-thinning treatments to prevent clots, help you take meaningful steps to protect your heart and your health.

Key takeaways

Strokes continue to have a heavy impact, causing death and disability around the world. The good news is that many strokes are preventable. By understanding what triggers them, recognising the warning signs, and taking steps to reduce risk, we can protect ourselves and the people we care about.

Simple choices can make a real difference. And yet, when a stroke does occur, time is everything. Knowing the signs and acting FAST isn’t just important, it can save a life and make recovery easier. Awareness, action, and care can turn the tide against stroke.
