Health conditions

  • High blood pressure. The risk of a stroke begins to increase at blood pressure readings higher than 140/90 millimeters of mercury (mm Hg). Your health care provider will help you decide on a target blood pressure based on your age, whether you have diabetes and other factors.
  • High cholesterol. Eating less cholesterol and fat, especially saturated fat and trans fat, may reduce the plaques in your arteries. If you can’t control your cholesterol through dietary changes alone, your provider may prescribe a statin or another type of cholesterol-lowering medication.
  • Cardiovascular disease. This includes heart failure, a heart defect, a heart infection or a heart rhythm that isn’t typical.
  • Carotid artery disease. In this condition, the blood vessels in the neck that lead to the brain become clogged.
  • Peripheral artery disease (PAD). PAD causes the blood vessels that carry blood to the arms and legs to become clogged.
  • Diabetes. Diabetes increases the severity of atherosclerosis — narrowing of the arteries due to accumulation of fatty deposits — and the speed with which it develops.
  • High levels of homocysteine. Elevated levels of this amino acid in the blood can cause the arteries to thicken and scar, which makes them more susceptible to clots.
  • Excess weight. Obesity, especially carrying extra weight in the abdominal area, increases stroke risk in both men and women.
  • COVID-19. There is evidence that SARS-CoV-2, the virus that causes COVID-19, may raise the risk of stroke.

Lifestyle choices

  • Cigarette smoking. Quit smoking to reduce your risk of a TIA and a stroke. Smoking increases your risk of blood clots, raises your blood pressure and contributes to the development of cholesterol-containing fatty deposits in the arteries (atherosclerosis).
  • Physical inactivity. Engaging in 30 minutes of moderate-intensity exercise most days helps reduce risk.
  • Poor nutrition. Reducing your intake of fat and salt decreases your risk of a TIA and a stroke.

  • Limit sodium. If you have high blood pressure, avoiding salty foods and not adding salt to food may reduce your blood pressure. Avoiding salt may not prevent hypertension, but excess sodium may increase blood pressure in people who are sensitive to sodium.
  • Exercise regularly. If you have high blood pressure, regular exercise is one of the few ways you can lower your blood pressure without drugs.
  • Limit alcohol intake. Drink alcohol in moderation, if at all. The recommended limit is no more than one drink daily for women and two a day for men.
