When you visit your primary care provider, one of the first steps in your appointment is a blood pressure check. This quick measurement gives your care team important information about how well your heart and blood vessels are working. By checking your blood pressure at every visit, your provider can identify changes early and work with you to support your long‑term health. 

Why Blood Pressure Matters 

Blood pressure is the force of your blood pushing against your blood vessels. When that pressure stays too high, it can harm your body over time. Your heart works around the clock. High blood pressure (hypertension) makes its job harder, and without regular blood pressure checks, it can easily go undetected.  

According to the American Heart Association, heart disease is the leading cause of death in the United States for both men and women. Understanding your blood pressure — and checking it often — is one of the easiest ways to protect your heart. 

“Staying on top of your blood pressure is one of the simplest ways to stay healthy,” Vicki Cornelius, RN, BSN, Chief Nursing Officer at Covenant Health Claiborne. “It gives you real information about what’s happening inside your body.” 

Hypertension increases your risk for: 

  • Heart disease 
  • Heart failure 
  • Stroke 
  • Atrial fibrillation 
  • Kidney disease 
  • Dementia

“Treating hypertension early and to goal reduces the long-term risks of heart attack and stroke as well as reducing the risk of progressive kidney disease,” says Rodney Diehl, DO, interventional cardiologist with Knoxville Heart Group. “It may also help reduce the risk of certain types of dementia.”  Nearly half of American adults have hypertension, and many don’t know it. But you can manage it — and Covenant Health is here to help. 

Understanding Your Numbers 

Every blood pressure reading includes two numbers: 

  • Systolic (top number): Pressure when your heart beats 
  • Diastolic (bottom number): Pressure when your heart rests 

Your ideal numbers may vary based on your age, health history or pregnancy status. Most adults should aim for a blood pressure below 130/80. You may have hypertension if your reading is 130/80 or higher. A reading over 180/120 is serious, and you should contact your provider right away. 

How to Check Your Blood Pressure at Home 

A home blood pressure monitor lets you track your numbers between appointments. This is important for people with higher risk factors for heart disease, such as: 

  • Hypertension 
  • High Cholesterol 
  • Diabetes 
  • Obesity 

For the most accurate reading, avoid the following for 30 minutes prior to taking your blood pressure: 

  • Smoking 
  • Exercising 
  • Drinking caffeine 
  • Drinking alcohol 

During the Reading: 

  • Rest for 5 minutes 
  • Sit upright with feet flat on the floor 
  • Keep your arm supported at heart level 
  • Don’t talk 
  • Keep your legs uncrossed 
  • Place the cuff on bare skin above your elbow 

Healthy Habits Help Your Heart 

High blood pressure is the most common reason people develop heart disease. But you can lower your risks. Healthy eating, regular movement, good sleep and medication (when prescribed) can make a major difference. 

“Simple changes add up,” notes Dr. Diehl. “You don’t have to do everything at once. You just have to start.”
