The basics of blood pressure

One in three Americans has high blood pressure, also called hypertension. Without treatment, they are three times more likely to get heart disease, and four times more likely to have a stroke. If you’re concerned about your blood pressure, you’ll want to be proactive. You can start by learning simple ways to lower it and protect your heart.

What is blood pressure?

Blood pressure is the amount of force your blood uses to get through your arteries. When your heart pumps, it uses force to push blood out to your arteries. They bring it to your body’s cells and tissues. If your blood pressure is too high, it can cause health issues. The only way to know your blood pressure is to measure it.

 

Blood pressure numbers
 

Two numbers make up a blood pressure reading: Less than 120/80 (or “120 over 80,” as you’d say) is considered normal.

  1. The top number: measures the force when your heart muscle is squeezing and actively pushing blood throughout your body. That’s called your “systolic” pressure 
  2. The bottom number (or “diastolic” pressure): measures the lesser force when your heart is relaxed 

It’s normal for blood pressure to rise and fall throughout the day. Blood pressure naturally goes up in response to physical effort or emotional stress. Your pressure drops when you relax. If one or both numbers are always high over time, that’s a sign that something is wrong.

 

 

High blood pressure facts
 

  • A blood pressure cuff is called a sphygmomanometer 
  • Normal blood pressure is under 120/80
  • High blood pressure is above 130/80
  • 1 in 3 Americans is affected by high blood pressure
  • High blood pressure is the 2nd major risk factor for heart disease after smoking
  • Lowering your blood pressure extends your life by 5 years

Why is high blood pressure bad?

Why is high blood pressure bad?

High blood pressure doesn’t cause any noticeable symptoms at first. So why is it a problem? Untreated, it can lead to many serious problems, including:
 

  • Blindness or other eye problems

  • Kidney disease

  • Leg pain and trouble walking from peripheral artery disease 

  • Problems during pregnancy

  • Heart attack

  • Stroke  

What causes high blood pressure?

There are two main causes of high blood pressure: lifestyle and genetics (how traits are passed down in the family). 

 

Unhealthy habits can put you at risk. These include:
 

  • Poor diet 

  • Not enough exercise

  • Heavy drinking and/or smoking 

  • Stress and/or not enough sleep 

 

You’re also more likely to have high blood pressure if you:
 

  • Have a family history of high blood pressure, heart disease or diabetes

  • Are older than age 55

  • Are African American 

  • Are pregnant

How to lower your blood pressure 

 

You already know that you should exercise, quit smoking and cut back on alcohol. Besides those healthy moves, here are five other ways proven to lower your blood pressure.

 

1. Improve your diet and/or lose weight. If you’re carrying around extra pounds, dropping them will lower your blood pressure. But even people who are at a healthy weight can stand to improve their diet. The Dietary Approaches to Stop Hypertension (DASH) eating plan was made just for people with high blood pressure. The diet recommends more vegetables and whole grains and fewer fatty and sweetened foods. Consider probiotics as well; some studies suggest that gut bacteria influences blood pressure.

 

2. Relax and manage stress. Blood pressure rises in response to stress. Finding ways to manage stress can help fight high blood pressure. That can mean yoga, meditation, listening to music, spending time in nature ― whatever works best for you.  

 

Learn simple ways to reduce your stress level in 10 minutes or less.

 

3. Take your medication. For some people, healthy habits are not enough: High blood pressure is in their genes (it runs in their family). So taking prescriptions exactly as the doctor says is what’s more helpful. 

 

4. See your doctor twice a year. People who see their doctor at least twice a year are 3.2 times more likely to keep their blood pressure under control, according to the American Heart Association. Make sure to discuss with your doctor all the prescription and over-the-counter medications you take. Many drugs and natural remedies can add to high blood pressure when taken regularly. These include:
 

  • Asthma rescue inhalers
  • Pain relievers
  • Decongestants
  • Gingko
  • Licorice

5. Check your blood pressure at home, too. People who check their blood pressure at home ― along with regular doctor visits ― tend to lower their blood pressure more than patients who rely on doctor visits alone. The connection isn’t clear, but it may reflect a better understanding of how personal habits can affect blood pressure.
