Osteoporosis after a stroke can increase the risk of fractures, particularly if mobility has been reduced or falls have occurred. Learn why stroke survivors may be at greater risk, how osteoporosis is diagnosed, and what you can do to protect your bones and maintain your independence.

After a stroke...

Most people focus on recovery.

Walking again.

Using their hand.

Improving their speech.

Very few people think about their bones.

But months after a stroke...

Bones can become weaker.

A simple fall can result in a fracture.

Something that once caused a bruise...

May now cause a broken bone.

The good news is that osteoporosis can often be prevented, detected and managed.

✦ ✦ ✦

The Good News

Healthy bones respond to healthy habits.

Even after a stroke, there are many things you can do to help protect your bones and reduce your risk of fractures.

Small changes today may help prevent serious injuries in the future.

✦ ✦ ✦

What Is Osteoporosis?

Osteoporosis is a condition that causes bones to become weaker, thinner and more fragile.

As bones lose density, they become more likely to break.

A minor fall that would once have caused little harm may result in a fracture of the:

✓ Hip.

✓ Wrist.

✓ Spine.

✓ Shoulder.

Many people don't realise they have osteoporosis until they break a bone.

✦ ✦ ✦

Why Are Stroke Survivors More at Risk?

A stroke doesn't directly cause osteoporosis.

However, several changes after a stroke can increase the risk of bone loss.

Reduced Mobility

Bones stay strong when they regularly carry weight.

After a stroke, reduced walking and standing mean bones receive less stimulation.

Over time, bone density may decrease.

✦ ✦ ✦

Less Weight Bearing

If one leg is affected, you may naturally place more weight through your stronger side.

The affected leg may gradually lose bone strength because it is used less.

✦ ✦ ✦

Reduced Physical Activity

Exercise helps maintain healthy bones.

When activity levels fall after a stroke, bones may gradually become weaker.

✦ ✦ ✦

Vitamin D Deficiency

Many people spend less time outdoors during recovery.

Lower sunlight exposure may reduce vitamin D levels, which are important for healthy bones.

✦ ✦ ✦

Increased Falls Risk

Stroke survivors are often at greater risk of falls because of:

✓ Weakness.

✓ Foot drop.

✓ Balance problems.

✓ Visual changes.

✓ Fatigue.

Weak bones combined with falls increase the chance of fractures.

✦ ✦ ✦

Symptoms of Osteoporosis

Osteoporosis is often called a "silent condition."

It usually causes no symptoms until a fracture occurs.

Possible signs include:

✓ A broken bone after a minor fall.

✓ Loss of height.

✓ Back pain caused by spinal fractures.

✓ A stooped posture.

Many people have no warning signs at all.

✦ ✦ ✦

How Is Osteoporosis Diagnosed?

Your doctor may assess your:

✓ Medical history.

✓ Falls history.

✓ Family history.

✓ Medication.

✓ Lifestyle.

You may also be referred for a DEXA scan, a specialised X-ray that measures bone density.

This helps determine whether your bones have become weaker than expected.

✦ ✦ ✦

How Can You Protect Your Bones?

Stay Active

Weight-bearing activities encourage bones to remain strong.

Depending on your abilities, this may include:

✓ Walking.

✓ Standing exercises.

✓ Balance training.

✓ Strength exercises.

Always follow advice from your rehabilitation team.

✦ ✦ ✦

Eat a Bone-Healthy Diet

Healthy bones need nutrients including:

✓ Calcium.

✓ Vitamin D.

✓ Protein.

A balanced diet supports both bone health and stroke recovery.

✦ ✦ ✦

Spend Time Outdoors

Safe sunlight exposure helps your body produce vitamin D.

If you're unable to get enough sunlight, your healthcare professional may recommend supplements.

✦ ✦ ✦

Stop Smoking

Smoking increases bone loss and affects overall health.

Stopping smoking benefits both your bones and your heart.

✦ ✦ ✦

Limit Alcohol

Excessive alcohol increases both falls risk and bone loss.

Moderation is important.

✦ ✦ ✦

Preventing Falls

Reducing falls is one of the best ways to prevent fractures.

Simple changes include:

✓ Wearing supportive footwear.

✓ Removing loose rugs.

✓ Keeping walkways clear.

✓ Improving lighting.

✓ Using walking aids if recommended.

✓ Continuing balance exercises.

Every prevented fall helps protect your bones.

✦ ✦ ✦

Medical Treatment

Some people may benefit from medication to strengthen their bones.

Your doctor will decide whether treatment is appropriate based on your:

✓ Bone density.

✓ Fracture risk.

✓ Medical history.

Continue taking medication exactly as prescribed.

✦ ✦ ✦

When Should You Speak to Your Doctor?

Arrange a medical review if you:

✓ Break a bone after a minor fall.

✓ Notice a loss of height.

✓ Develop persistent back pain.

✓ Have repeated falls.

✓ Have concerns about your bone health.

Early assessment may reduce your future fracture risk.

✦ ✦ ✦

My Perspective

During stroke recovery it's easy to focus only on movement.

I certainly did.

But recovery is about much more than learning to walk again.

It's also about protecting the body that carries you through recovery.

Looking after your bones today may help preserve your independence tomorrow.

Frequently Asked Questions

Does Every Stroke Survivor Develop Osteoporosis?

No.

However, reduced mobility and reduced weight-bearing can increase the risk, particularly during long recoveries.

✦ ✦ ✦

Can Exercise Help Prevent Osteoporosis?

Yes.

Weight-bearing and strengthening exercises help maintain healthy bones while also supporting stroke recovery.

✦ ✦ ✦

Is Osteoporosis Reversible?

Treatment can often slow bone loss, improve bone strength and reduce fracture risk.

Your doctor can advise on the most appropriate treatment for your situation.

✦ ✦ ✦

Should I Take Calcium Supplements?

Not everyone needs supplements.

Your healthcare professional can advise whether calcium or vitamin D supplements are appropriate for you.
