Strokes can happen at any age, even to babies in the womb. Still, the odds of a stroke climb quickly after middle age.

To cut your odds of having a stroke:

Avoid tobacco.Smoking cigarettes and chewing tobacco — even — cause physical changes in your body. They can thicken your blood and make it more likely to clot and cause fatty buildup in your arteries.

Control your cholesterol levels. High levels of , or “>cholesterol, make it more likely that plaque will build up in your arteries, putting you at greater risk of a clot that causes a heart attack or stroke.

Check your weight and waist. Your doctor can let you know if these numbers are in a healthy range. If you have a belly that’s bigger than 40 inches around for men or more than 35 inches for women, that may be especially risky.
