Preventing Stroke in Women of All Ages

Stroke can happen in an instant, and it can be a life-altering event. It inspires a fair amount of fear and worry in many. And for good reason. A stroke can strike anyone—no matter your age, ethnicity, or sex. There is no typical stroke victim.

 A stroke happens when blood can’t flow to the brain. A blood clot or bleeding in the brain is most often responsible. In the United States stroke is now more common in women than men. More than half of the 795,000 strokes that occur each year happen to women, and 60 percent of stroke deaths occur in women. 

The American Heart Association  recently updated its guidelines for preventing strokes in women. Certain factors can boost the chances of having a stroke. While women have many of the same risk factors for stroke as men high blood pressure, smoking and diabetes they also have other risk factors to consider.

Hormonal changes can raise a woman’s risk for stroke. During pregnancy, some mothers-to-be may develop preeclampsia – a form of high blood pressure. Certain birth control pills can also put a woman at higher risk for stroke – especially if she smokes, is older than 35 and suffers from certain types of migraines.

People with atrial fibrillation (AF) are four to five times more likely to have a stroke. AF more commonly occurs in women because AF afflicts older people and women tend to live longer than men. 

Know the Signs of Stroke 

During a stroke, both men and women often report that the following symptoms appear suddenly:

• Numbness or weakness in the face or limbs
• Trouble seeing
• Dizziness or loss of balance and coordination
• Confusion and trouble speaking or understanding
• Severe headache with no known cause

Other symptoms may include hiccups, nausea, chest pain, fatigue, shortness of breath, and a racing heartbeat.

Recognizing these symptoms and getting immediate medical care when they occur can save your life. It may also lower your risk for more serious disability. Compared with men, women have a lower quality of life after a stroke. One recent study found women were more likely to have trouble moving and doing daily activities up to a year after their stroke.

If you suspect you or a loved one is having a stroke, call 911 right away. Time is essential for receiving lifesaving treatment. 

Eight Ways to Help Women Prevent a Stroke

You can‘t change your family history, but you can change some behaviors to help reduce your risk of stroke.

1. Lower your blood pressure. Maintain a blood pressure of less than 120 (top number) over 80 or less (bottom number). To reach the sweet spot, reduce the salt in your diet, avoiding high-cholesterol foods and eat a balanced diet. Take medication if it is recommended by your doctor.
2. Maintain a healthy weight. Keep your body mass index (BMI) between 20 and 25.
3. Exercise. Engage in moderate intensity physical activity at least five days a week for 30 minutes.
4. Drink in moderation. Limit your drinking to one serving a day. One standard-sized drink is either a 5-ounce glass of wine, a 12-ounce beer or 1.5-ounce glass of hard liquor.
5. Take a baby aspirin. Talk to your doctor to make sure aspirin is safe and appropriate for you.
6. Treat atrial fibrillation. Atrial fibrillation is a form of irregular heartbeat that causes clots to form in the heart. See your doctor for the best treatment.
7. Monitor diabetes. High blood sugar damages blood vessels over time, making clots more likely to form inside them. Monitor your blood sugar and keep it under control. 
8. Quit smoking. Smoking speeds up clot formation in a couple of different ways. It thickens your blood, and it increases the amount of plaque buildup in the arteries.
