Here are new guidelines for preventing stroke, the nation's 4th biggest killer

The majority of strokes could be prevented, according to new guidelines aimed at helping people and their doctors do just that.

Stroke was the fourth leading cause of death in the U.S. in 2023, according to the Centers for Disease Control and Prevention, and more than half a million Americans have a stroke every year. But up to 80% of strokes may be preventable with better nutrition, exercise and identification of risk factors.

The first new guidelines on stroke prevention in 10 years from the American Stroke Association, a division of the American Heart Association, include recommendations for people and doctors that reflect a better understanding of who gets strokes and why, along with new drugs that can help reduce risk.

The good news is that the best way to reduce your risk for stroke is also the best way to reduce your risk for a whole host of health problems — eat a healthy diet, move your body and don't smoke. The bad news is that it's not always so easy to sustain.
