Women and Stroke

women and stroke

The lifetime risk of stroke for women between the ages of 55 and 75 in the United States is one in five. Stroke kills twice as many women as breast cancer does, making stroke the third leading cause of death for women.

 

Surprised? You're not alone. Many women do not know their risk of having a stroke.

 

These facts are alarming, but there is good news: four in five strokes are preventable. That's why it's important to know your risk for stroke and take action to reduce the risk.

 

 

What is a stroke?

 

A stroke happens when blood flow to an area of the brain is blocked or when a blood vessel in the brain bursts. Blood carries oxygen to cells in the body. When brain cells are starved of blood, they die.

 

Stroke is a medical emergency. It's important to get treatment as soon as possible. Some treatments for stroke work only if given within the first three hours after symptoms start. A delay in treatment increases the risk of permanent brain damage or death.

 

 

What puts women at risk for stroke?

 

High blood pressure, also called hypertension, is a main risk factor for stroke. More than two in five women have blood pressure greater than or equal to 130/80 mmHg or are taking medicine to control their blood pressure. Only about one in four of those women have their blood pressure controlled to below 130/80 mmHg.

 

Stroke risk increases with age, and women live longer than men.

 

Women also have unique risk factors for stroke, including:

  •  Using certain types of birth control medicines, especially if they also smoke. About one in eight women smoke.
  • Having higher rates of depression.

 

 

Why are African American women at higher risk for stroke?

 

Stroke is the third leading cause of death among African American women, and they are more likely to die from a stroke than non-Hispanic white women or Hispanics in the United States. African Americans have the highest rate of death due to stroke.

 

Almost half of African Americans have a risk factors that can lead to a stroke.

  • More than two in five African American women are diagnosed high blood pressure (greater than or equal to 140/90 mmHg), which is a much higher rate than white women have.
  • African American women are diagnosed with higher rates of obesity (nearly three in five) and diabetes (more than one in eight), conditions that increase the risk for stroke.
  • Eating too much salt or sodium can raise your blood pressure, putting you at higher risk of stroke. Researchers think there may be a gene that makes African Americans more sensitive to the effects of salt, which in turn increases the risk of developing high blood pressure.
  • Sickle cell disease, a common genetic disorder in African Americans, can lead to a stroke. About one in 365 black or African American babies are born with sickle cell disease.
  • Smoking greatly increases stroke risk. About one in seven black or African American women smoke.

 

Stroke is the third leading cause of death for Hispanic women.

  • High blood pressure is one of the main risk factors for a stroke. About one in four Hispanic women have blood pressure above 140/90 mmHg, and nearly half of them do not have it under control.
  • People with diabetes are at a higher risk of stroke. More than one in nine Hispanic women have diabetes - including many who don't know they have the disease. Among adults of Hispanic origin, diabetes is the most common in people of Mexican and Puerto Rican ancestry.
  • Obesity increases the risk of stroke. About half of Hispanic women have obesity.

 

 

How can I prevent stroke?

 

Most strokes can be prevented by keeping medical conditions under control and making healthy lifestyle changes:

 

Know your ABCS of heart and brain health:

  • Aspirin: Aspirin may help reduce your risk for stroke, but you should check with your doctor before taking aspirin, because it can make some types of stroke worse.
  • Blood pressure: Control your blood pressure with healthy lifestyle changes and take your blood pressure medicines as directed.
  • Cholesterol: Manage your cholesterol with healthy lifestyle changes and take your medicine as directed.
  • Smoking: Don't start smoking. If you do smoke, learn how to quit.

 

Make lifestyle changes:

  • Eat healthy: Choose healthy foods most of the time, including foods with less salt, or sodium, to lower your blood pressure, and that are rich in fiber and whole grains to manage your cholesterol.
  • Get regular physical activity: Regular activity helps you reach and maintain a healthy weight and keeps your heart and blood vessels healthier.

 

Work with your health care team:

  • Talk to your doctor about your chances of having a stroke, including your age and whether anyone in your family has had a stroke.
  • Get other health conditions under control, such as diabetes or heart disease.
