Blood Pressure: Do You Know Your Numbers?

Emmi hadn’t gone to the doctor in quite a while. When she finally did, she was surprised to learn she had high blood pressure (also called hypertension). But she felt just fine – how could something be wrong?

She’s not alone. Almost half of people in the United States have high blood pressure. About 1 in 4 don’t even know it, which is why hypertension is called “the silent killer”. You may feel fine, but high blood pressure can still harm your body. It raises the risk of heart disease, heart failure, kidney problems, and stroke.

Blood pressure is considered high if it’s 130/80 mmHg or higher.

About 1 in 10 women ages 20-44 have high blood pressure, and about 40% of these women don’t have it under control. This can be very dangerous for a mom and baby during pregnancy.

Gestational Hypertension (high blood pressure during pregnancy) is:

  • Diagnosed after 20 weeks of pregnancy
  • When blood pressure is 140/90 or higher, checked at least twice, 4 or more hours apart.

Women with high blood pressure during pregnancy should:

  • Have their blood pressure checked 7–10 days after delivery (but many do not).
  • Know that they are 6 times more likely to have a stroke during pregnancy.

It’s important to control blood pressure, especially before you get pregnant. If you’ve had high blood pressure in a past pregnancy, it’s important to keep checking and controlling it.

Blood Pressure and Children

Children should have yearly blood pressure checks starting at age 3. Children who are overweight are at higher risk of having high blood pressure and should be checked

Are You at Risk?

Risk Factors You Can't Change:

  • Family history of high blood pressure
  • Race/ethnicity
  • Age
  • Gender (men are at higher risk)
  • Chronic kidney disease
  • Obstructive Sleep Apnea (though it can be treated)

Risk Factors You Can Change:

  • ✓ Smoking and secondhand smoke
  • ✓ Diabetes
  • ✓ Being overweight or obese
  • ✓ High cholesterol
  • ✓ Unhealthy diet (too much salt, not enough potassium)
  • ✓ Drinking too much alcohol
  • ✓ Not getting enough physical exercise
Healthy Changes That Help Healthy Changes That Help

The good news is simple lifestyle changes can help lower your risk of high blood pressure. Here’s how:

Be more active.

Try to get 2 ½ hours of moderate physical activity or 75 minutes of vigorous activity each week.

  • Moderate activity includes: fast walking, bike-riding, water aerobics, mowing the lawn, and dancing.
  • Vigorous activity includes: jogging or running, swimming laps, riding a bike fast or on hills, and playing basketball or tennis.
Be more active.
Eat the DASH way

Eat the DASH way (Dietary Approach to Stop Hypertension).

  • Choose foods rich in potassium (bananas, beans, potatoes, yogurt, fish).
  • Eat more calcium-rich foods (milk, yogurt, cheese, greens, soy milk).
  • Add magnesium-rich foods (nuts, seeds, whole grains, spinach, beans).
  • Cut back on sugary drinks, sweets, and foods high in unhealthy fats.
  • Limit salt to 2,300 mg per day (less for kids). High-sodium foods include deli meats, sausage, canned foods, fast food, and instant meals. Check food labels:
  • ✓ 5% DV or less = low sodium
  • 20% DV or more = high sodium

Reach and maintain a healthy weight.

  • Extra weight makes your heart work harder and raises blood pressure.
  • Even losing a small amount – like 5 to 10 pounds – can help bring your numbers down.
  • Eating balanced meals, watching portion sizes, and staying active are healthy ways to reach and keep a good weight.
