Managing high blood pressure after a stroke is one of the most important steps you can take to reduce your risk of another stroke. High blood pressure damages blood vessels throughout the body and is the leading modifiable risk factor for stroke. Learn why controlling your blood pressure matters, the treatments available, and the lifestyle changes that can help protect your brain.

After your stroke...

Your doctor checks your blood pressure at every appointment.

You leave hospital with blood pressure tablets.

You begin checking your readings at home.

You start wondering...

"Why is blood pressure so important now?"

"What should my blood pressure be?"

These are questions almost every stroke survivor asks.

The Good News

High blood pressure can usually be managed successfully.

With the right medication, healthy lifestyle changes and regular monitoring, many people significantly reduce their risk of another stroke.

Every improvement helps protect your brain.

✦ ✦ ✦

Why Does High Blood Pressure Matter?

Blood pressure is the force of blood pushing against the walls of your arteries.

When it stays too high for a long time, it damages the blood vessels throughout your body.

This damage can:

✓ Narrow your arteries.

✓ Weaken blood vessel walls.

✓ Increase the risk of blood clots.

✓ Increase the risk of another stroke.

Controlling blood pressure is one of the most effective ways to prevent future strokes.

✦ ✦ ✦

Can High Blood Pressure Cause a Stroke?

Yes.

High blood pressure is the leading modifiable risk factor for both:

✓ Ischaemic stroke (caused by a blocked blood vessel).

✓ Haemorrhagic stroke (caused by bleeding in the brain).

Keeping your blood pressure under control helps lower the risk of both types.

✦ ✦ ✦

What Is a Healthy Blood Pressure?

Your healthcare professional will recommend a target based on your health and medical history.

For many people, the aim is to keep blood pressure well controlled over the long term.

Do not compare your target with someone else's.

Always follow the advice of your healthcare team.

✦ ✦ ✦

Symptoms of High Blood Pressure

High blood pressure is often called the "silent killer" because it usually causes no symptoms.

Many people feel completely well.

This is why regular monitoring is so important.

Very high blood pressure may sometimes cause:

✓ Severe headaches.

✓ Blurred vision.

✓ Dizziness.

✓ Shortness of breath.

✓ Nosebleeds.

However, most people experience no warning signs.

✦ ✦ ✦

How Is High Blood Pressure Treated?

Treatment usually involves both medication and lifestyle changes.

✦ ✦ ✦

Blood Pressure Medication

Your doctor may prescribe one or more medications to lower your blood pressure.

Common types include:

✓ ACE inhibitors.

✓ Angiotensin receptor blockers (ARBs).

✓ Calcium channel blockers.

✓ Diuretics.

✓ Beta-blockers (in some situations).

Take your medication exactly as prescribed.

Never stop taking it without medical advice.

✦ ✦ ✦

Reduce Salt

Eating too much salt can raise blood pressure.

Try to:

✓ Avoid adding salt at the table.

✓ Choose lower-salt foods where possible.

✓ Read food labels.

Small reductions can make a meaningful difference.

✦ ✦ ✦

Eat a Heart-Healthy Diet

Aim for a diet rich in:

✓ Fruit.

✓ Vegetables.

✓ Wholegrains.

✓ Beans and pulses.

✓ Fish.

✓ Lean protein.

✓ Healthy fats such as olive oil and nuts.

Limiting processed foods may also help reduce salt intake.

✦ ✦ ✦

Stay Physically Active

Regular physical activity helps:

✓ Lower blood pressure.

✓ Improve circulation.

✓ Maintain a healthy weight.

✓ Improve heart health.

Choose activities appropriate for your stage of recovery.

✦ ✦ ✦

Maintain a Healthy Weight

If you're overweight, even modest weight loss may help lower your blood pressure.

Focus on gradual, sustainable changes rather than quick fixes.

✦ ✦ ✦

Stop Smoking

Smoking damages blood vessels and increases stroke risk.

Stopping smoking is one of the most important decisions you can make for your long-term health.

✦ ✦ ✦

Limit Alcohol

Drinking too much alcohol can increase blood pressure.

If you drink alcohol, follow the advice given by your healthcare professional.

✦ ✦ ✦

Manage Stress

Stress doesn't usually cause long-term high blood pressure on its own, but it can contribute to temporary increases and make healthy habits harder to maintain.

Relaxation techniques, exercise and good sleep may help.

✦ ✦ ✦

Monitor Your Blood Pressure

Your healthcare professional may recommend checking your blood pressure at home.

Home monitoring can:

✓ Show how well your medication is working.

✓ Identify changes early.

✓ Help guide treatment decisions.

Measure your blood pressure as instructed and keep a record of your readings.

✦ ✦ ✦

Tips for Family and Carers

If you're supporting someone after a stroke:

✓ Encourage them to take their medication every day.

✓ Help prepare healthy meals.

✓ Encourage regular exercise.

✓ Support home blood pressure monitoring if recommended.

✓ Attend appointments if appropriate.

Healthy habits are often easier when the whole family gets involved.

✦ ✦ ✦

When Should You Seek Medical Advice?

Arrange an appointment with your healthcare professional if:

✓ Your blood pressure remains consistently above your target.

✓ You develop medication side effects.

✓ You feel dizzy after starting treatment.

✓ You have concerns about your blood pressure readings.

Seek emergency medical attention immediately if you develop:

✓ Sudden facial drooping.

✓ New arm or leg weakness.

✓ Slurred speech.

✓ Sudden vision loss.

✓ Severe confusion.

✓ A sudden, severe headache unlike anything you've experienced before.

These could be signs of another stroke or another medical emergency.

My Perspective

High blood pressure doesn't usually make you feel unwell.

That's what makes it dangerous.

You may feel completely normal...

While your blood vessels are under constant strain.

Taking your medication...

Checking your blood pressure...

Making healthy choices...

May not feel dramatic.

But these small daily habits are some of the most powerful ways to protect the recovery you've worked so hard to achieve.
