Risk factors

Many factors can increase your stroke risk. Potentially treatable stroke risk factors include:

Lifestyle risk factors

• Being overweight or obese
• Physical inactivity
• Heavy or binge drinking
• Use of illegal drugs such as cocaine and methamphetamine

Medical risk factors

• High blood pressure
• Cigarette smoking or secondhand smoke exposure
• High cholesterol
• Diabetes
• Obstructive sleep apnea
• Cardiovascular disease, including heart failure, heart defects, heart infection or abnormal heart rhythm, such as atrial fibrillation
• Personal or family history of stroke, heart attack or transient ischemic attack
• COVID-19 infection

Other factors associated with a higher risk of stroke include:

• Age — People age 55 or older have a higher risk of stroke than do younger people.
• Race — African Americans have a higher risk of stroke than do people of other races.
• Sex — Men have a higher risk of stroke than women. Women are usually older when they have strokes, and they're more likely to die of strokes than are men.
• Hormones — Use of birth control pills or hormone therapies that include estrogen increases risk.
