Many strokes can be prevented by managing risk factors and adopting a healthy lifestyle. Controlling high blood pressure, diabetes, and high cholesterol through medications and lifestyle changes can significantly reduce stroke risk. Quitting smoking, maintaining a healthy weight, exercising regularly, and eating a diet rich in fruits, vegetables, and whole grains are also important preventive measures. For those at high risk, medications like anticoagulants or antiplatelet drugs may be prescribed to prevent blood clots. A study published in the Lancet found that addressing modifiable risk factors could prevent up to 90% of strokes worldwide.
