During a study I conducted, 77% reported taking their blood pressure incorrectly. Misdiagnosis and overtreatment of hypertension is a problem in America.
High blood pressure, or hypertension, is a very common condition. 1 in 3 Americans are diagnosed with it today. Hypertension is a leading risk factor for the development of cardiovascular and other complications, particularly stroke, heart attack, and kidney disease. There is no question that identifying and effectively treating hypertension saves lives and greatly reduces the risk of these life-threatening events.
We are fortunate to have many medications available that can reduce blood pressure back to normal and greatly reduce cardiovascular risk.
As a hypertension specialist, my number one goal for each patient is a normal blood pressure using the least amount of medication necessary. This is achievable with almost every patient.
All the conclusions from studies on the risks of hypertension and the benefits of treatment are based on blood pressure measurements that are taken after patients have been sitting quietly for 5 minutes or so. That’s because it takes a few minutes for our blood pressure to settle down to a steady, resting level. And that’s why every guideline recommends that patients sit quietly for 5 minutes before measurements are taken.
But in a clinical setting, like a visit to the doctor's office, a patient's blood pressure is often taken right away. Likewise, when people measure their own blood pressure at home, most do it without waiting.
Readings obtained without waiting can be 5 or 10 millimeters, or more, above our resting blood pressure level.
diagnosis and treatment of patients who might not have high blood pressure to start with and an unnecessary increase in medication for patients who have already been diagnosed and are taking medication.
Obviously, diagnosing and medicating someone for hypertension who doesn’t have high blood pressure isn’t good.
Overtreating, aside from additional cost, increases the risk of side effects, and of lowering blood pressure too much. This can cause fatigue, lightheadedness, and even fainting.
I regularly see new patients who are concerned because their blood pressure readings have remained elevated despite treatment. I found that many of those patients were taking their readings without waiting. Many ended up with lower readings when they waited the recommended 5 minutes before taking their blood pressure.
My decades of clinical experience agree with these results. I’ve followed the blood pressure of many patients during periods of severe stress in their lives. While their blood pressure may temporarily increase, it eventually falls back into a normal range and does not directly lead to persisting hypertension.
So how often do Americans measure their blood pressure without waiting?
In a study we published, (Nonadherence to Recommended Guidelines for Blood Pressure Measurement. Levy,J, Gerber, LM, Wu, X, Mann, SJ. J Clin Hypertens.
2016;18:1157), we asked patients if their blood pressure measurements were taken by a physician, nurse, technician, or themselves with or without waiting at least a few minutes.
The numbers were staggering!
I often hear how patients are brought into a room, seated, and their blood pressure is measured immediately.
In fairness, physicians are often pressed for time. But the importance of waiting a few minutes can mean the difference between diagnosis, overmedicating, or worse.
Yes, physicians should follow the guidelines, but more importantly, you (the patient) should feel empowered to check your blood pressure at home.
I want to emphasize the importance of measuring your blood pressure and ensuring it is in the “normal” range. To avoid overtreatment or a misdiagnosis, make sure you are taking your blood pressure, or having it taken, per the recommendation of sitting quietly for a few minutes before taking the reading. It’s time to bring attention to this problem.
This award-winning book by Dr. Mann dives deep into the relationship between repressed emotion and illness. Our ability to repress emotions is a vital gift of evolution, but, silently, the emotions we've repressed do persist and can affect our health years later. This recognition can lead to new pathways to understanding, treatment, and healing.
