Approximately 1 in 3 American adults has high blood pressure. In recognition of High Blood Pressure Awareness Month, Phillip Hecht, MD, a cardiologist on the medical staff at Baylor Regional Medical Center at Grapevine, presents these basic truths about hypertension.
1. Blood pressure is actually two separate measurements.
Expressed in millimeters of mercury (mmHg), the top number, systolic blood pressure, refers to the pressure inside the artery when the heart contracts and pumps blood through the body. The bottom number, diastolic blood pressure, is the lowest blood pressure in the arteries, which occurs between heartbeats.
2. Your blood pressure fluctuates throughout the day.
According to the American Heart Association, the optimal reading for adults is 120/80 mmHg; 140/90 or higher is considered hypertension. Because your numbers move up and down, a one-time reading in the doctor’s office won’t show the big picture. It is recommended to measure it over time to determine whether it’s remaining steady or inching slowly upward.
3. Hypertension has no symptoms.
In fact, you could have it for years and not know it. Young or old, even if you “feel fine,” have your blood pressure checked at least once a year. Left untreated, hypertension can lead to serious complications you don’t want to face: heart attack, heart failure, stroke and kidney disease.
4. Lifestyle changes can help lower blood pressure.
Quitting smoking, achieving a healthy weight and exercising regularly are a great start. Salt is a major culprit. Aim for 2,300 mg or less daily. You can follow a low-sodium diet like the DASH diet (Dietary Approaches to Stop Hypertension), rich in fruits, vegetables and whole grains. Simply decreasing salt in your diet may lower your systolic blood pressure by 10 points.
5. Medication may also be needed.
Even with lifestyle modifications, controlling hypertension may require medication. Your doctor may prescribe one or a combination based on your age, medical history and ethnicity. In African Americans, for example, hypertension tends to be more difficult to control, and certain medications are more effective than others.
