Stroke: What You Can Do to Reduce Your Risk

Recent high-profile stroke cases have helped raise awareness that strokes can happen at any age. While stroke is often associated with older adults, research shows the condition is becoming increasingly common among younger people.

According to the National Stroke Association, there has been a significant increase in stroke-related hospitalizations among adults ages 18 to 65 over the last decade.

Understanding stroke risk factors, warning signs, treatment options, and prevention strategies can help protect your health and potentially save a life.

What Is a Stroke?

A stroke occurs when blood flow to part of the brain is interrupted, causing brain cells to become damaged or die.

There are two primary types of stroke:

Ischemic Stroke

Approximately 80% of strokes are ischemic strokes.

This type of stroke occurs when a blood clot blocks blood flow to part of the brain. The clot may form:

• In the brain's blood vessels
• In blood vessels leading to the brain
• Elsewhere in the body and travel to the brain

Without oxygen-rich blood, brain cells begin to die within minutes.

Hemorrhagic Stroke

A hemorrhagic stroke occurs when a blood vessel in the brain ruptures and bleeds into surrounding brain tissue.

Common causes include:

• High blood pressure
• Brain aneurysms
• Genetic factors affecting blood vessels

The bleeding damages brain cells and can quickly become life-threatening.

Why Stroke Is So Serious

Both ischemic and hemorrhagic strokes can cause significant brain damage.

Stroke is:

• One of the leading causes of death in the United States
• A leading cause of long-term disability
• A major cause of paralysis and communication difficulties

The faster treatment begins, the better the chance of preserving brain function and reducing disability.

Medical Conditions That Increase Stroke Risk

Although stroke can affect anyone, certain health conditions significantly increase the likelihood of having one.

High Blood Pressure

High blood pressure is the leading risk factor for stroke.

Over time, elevated blood pressure can:

• Damage blood vessels in the brain
• Cause arteries to narrow
• Lead to blood vessel rupture
• Increase the risk of blood clots

Managing blood pressure is one of the most effective ways to reduce stroke risk.

High Cholesterol

Cholesterol is a waxy substance produced by the liver and found in certain foods.

When levels of LDL ("bad") cholesterol become too high, cholesterol can build up inside arteries, causing:

• Narrowed blood vessels
• Reduced blood flow
• Increased risk of stroke and heart disease

Maintaining healthy cholesterol levels can help protect blood vessels throughout the body.

Diabetes

Diabetes can damage blood vessels and contribute to arterial blockages.

People with diabetes often have additional stroke risk factors, including:

• High blood pressure
• Unhealthy cholesterol levels
• Obesity

Proper diabetes management is essential for reducing stroke risk.

Lifestyle Habits That Can Increase Stroke Risk

Daily lifestyle choices play an important role in stroke prevention.

Poor Diet

Diets high in:

• Saturated fats
• Trans fats
• Cholesterol
• Sodium

have been linked to stroke and other cardiovascular diseases.

Excess sodium can also contribute to high blood pressure.

Physical Inactivity

A lack of regular exercise increases the risk of several stroke-related conditions, including:

• High blood pressure
• High cholesterol
• Obesity
• Diabetes

Obesity

Obesity is associated with several stroke risk factors, including:

• Elevated cholesterol levels
• High blood pressure
• Diabetes
• Increased triglycerides

Smoking

Smoking damages the heart and blood vessels while reducing oxygen delivery throughout the body.

Cigarette smoking can:

• Raise blood pressure
• Damage artery walls
• Increase the risk of blood clots
• Significantly increase stroke risk

Know the Warning Signs of Stroke

Every minute matters during a stroke.

Approximately 1.9 million brain cells die each minute a stroke goes untreated, increasing the risk of disability and death.

Seek immediate medical attention if you experience or observe any of the following symptoms:

• Sudden weakness or numbness in the face, arm, or leg, especially on one side of the body
• Sudden confusion
• Difficulty speaking or understanding speech
• Sudden vision loss or changes
• Loss of coordination or balance
• Unexplained dizziness
• Sudden severe headache with no known cause
• Sudden falls

Remember F.A.S.T.

One of the easiest ways to recognize a stroke is the F.A.S.T. test.

F – Face Drooping

Ask the person to smile.

Does one side of the face droop?

A – Arm Weakness

Ask the person to raise both arms.

Does one arm drift downward?

S – Speech Difficulty

Ask the person to repeat a simple phrase.

Is speech slurred or unusual?

T – Time to Call 9-1-1

If you notice any of these symptoms, call 9-1-1 immediately and note the time symptoms began.

Stroke Treatment: Why Quick Action Matters

Prompt treatment can improve survival rates and reduce long-term complications.

Treatment for Ischemic Stroke

For ischemic strokes, treatment may include:

• Tissue plasminogen activator (tPA), a clot-busting medication
• Mechanical thrombectomy, a procedure that removes the clot using specialized devices

Treatment for Hemorrhagic Stroke

For hemorrhagic strokes, treatment focuses on:

• Controlling bleeding
• Relieving pressure on the brain
• Repairing damaged blood vessels
• Treating aneurysms when present

How to Reduce Your Stroke Risk

Many strokes can be prevented through healthy lifestyle choices and proper medical management.

Healthy Habits for Stroke Prevention

• Exercise at least 30 minutes a day, five days per week
• Maintain a healthy weight
• Stop smoking
• Limit alcohol consumption
• Manage diabetes
• Control high blood pressure
• Monitor cholesterol levels

Heart-Healthy Nutrition Tips

Consider making these dietary changes:

• Keep portion sizes moderate
• Drink more water
• Limit salt intake
• Reduce added sugars
• Limit refined carbohydrates
• Cook with olive, canola, corn, or safflower oil
• Choose fresh, lean meats
• Trim visible fat before cooking
• Eat plenty of fruits and vegetables

These small changes can have a significant impact on cardiovascular and brain health over time.

Recovery After a Stroke

Every stroke survivor's recovery journey is unique.

Recovery depends on several factors, including:

• The severity of the stroke
• The area of the brain affected
• How quickly treatment was received

Some individuals spend a few days in the hospital, while others may require extended rehabilitation.

Recovery Is an Ongoing Process

Stroke recovery often involves improvements in:

• Physical strength and mobility
• Communication skills
• Emotional well-being
• Cognitive function
• Daily living activities

Many survivors continue to make progress for months or even years after a stroke.

Prevention Is Your Best Defense

While stroke can be life-changing, many risk factors are manageable.

By maintaining a healthy lifestyle, managing chronic medical conditions, recognizing warning signs, and seeking immediate treatment when symptoms occur, you can significantly reduce your risk of stroke and improve your overall health.

Knowledge is one of the most powerful tools for stroke prevention. Understanding your risk factors today can help protect your future tomorrow.
