High blood pressure is the single biggest controllable risk factor for stroke. It damages artery walls over years, making clots and bleeds far more likely.
A healthy reading is below 120/80. Consistently above 140/90 counts as hypertension. Many people feel nothing — which is why it is called the silent killer.
Lowering blood pressure cuts stroke risk dramatically. The most effective steps: reduce salt, exercise 30 minutes most days, maintain a healthy weight, limit alcohol, and stop smoking.
Medication matters too. If your doctor prescribes blood pressure tablets, take them daily — stopping suddenly can be dangerous. Most people need long-term treatment.
Check your blood pressure at least yearly after age 40, or sooner if you have diabetes, are overweight, or have a family history of stroke or heart disease.
