You can help prevent stroke in many cases by modifying your risk factors.
A stroke can be a very disabling event, leading to problems with memory, thought, movement and speech. You can help to prevent strokes by controlling your risk factors.
But most strokes can be prevented. You and your doctor can identify your stroke-risk factors, and then take action to reduce them.
Control High Blood Pressure
High blood pressure, also called hypertension, is one of the strongest risk factors for strokes. It is also a risk factor that can be controlled, unlike your age, genetic makeup and race
Controlling your blood pressure may require the daily use of one or more medications. Several studies have proven that you can reduce your risk of having a stroke by 42% by lowering your blood pressure as little as five points.
If your blood pressure's top number (systolic) is between 120 and 139, or your bottom number (diastolic) is between 80 and 89, you have "pre-hypertension," a recently added category that says, "You may be heading toward full-blown high blood pressure." Because you are at risk of strokes and heart disease, it is important that you, like all people with high blood pressure, alter your eating habits and lifestyle. Here's how:
If you have high blood pressure and your numbers remain above 140 (systolic) or above 90 (diastolic) after you make lifestyle changes, your doctor will prescribe one or more medications to lower your blood pressure. It is important that you not miss doses. Most people with high blood pressure require lifetime treatment with medication.
