Know Your Risk: Common Factors That Increase Stroke Risk

The #1 risk factor for stroke. High blood pressure puts stress on your blood vessels, making them more likely to burst or become blocked. If you have high blood pressure, work with your provider to manage it—sometimes medication, diet changes, and regular exercise can make a big difference.

A diet high in sodium, saturated fats, and processed foods can contribute to high cholesterol, high blood pressure, and diabetes—all of which raise stroke risk. Choosing more fruits, vegetables, whole grains, and lean proteins supports heart and brain health.

Smoking damages blood vessels, raises blood pressure, and increases the risk of blood clots. Quitting—even after years of smoking—can greatly reduce your stroke risk.

Regular movement helps lower blood pressure, manage weight, and improve circulation. Aim for at least 30 minutes of moderate activity most days—think brisk walking, gardening, or dancing around the kitchen.

Drinking too much alcohol can raise blood pressure and increase stroke risk. Moderation is key—no more than one drink per day for women, and two for men.

• Diabetes: High blood sugar can damage blood vessels over time.
• High cholesterol: Can lead to plaque buildup in arteries, narrowing them and increasing stroke risk.
• Atrial fibrillation: This type of irregular heartbeat can cause clots that may travel to the brain.

Your risk of stroke increases as you get older, especially after age 55.

If a close family member has had a stroke, your risk may be higher. Let your provider know about any family history of stroke or cardiovascular disease.

If you’ve had a previous stroke or TIA (mini-stroke), your risk of having another is significantly higher. Ongoing care and preventive measures are essential.

Women are at higher risk for certain types of strokes, particularly if they’re pregnant, using hormone-based birth control, or going through menopause. Talk to your provider about your individual risk during these times.
