High blood pressure is known as the "silent killer" because it usually doesn't come with symptoms, and it can be dangerous if left untreated. Show
The only way to know your blood pressure and keep track of your heart health is through accurate readings and frequent measurements. Here's what you need to know about your blood pressure reading and what it means for you. Blood pressure readingsBlood pressure is the force of blood pushing against the arteries in your body. It is measured by two numbers:
Blood pressure is measured in millimeters of mercury (mm Hg). To determine whether someone has high blood pressure, known medically as hypertension, doctors classify blood pressure readings into different categories. Shayanne Gal/InsiderNormal blood pressureNormal blood pressure is considered:
If you have a blood pressure reading around this number, it generally means your heart is healthy. However, even if you have normal blood pressure, certain factors can increase your risk of developing hypertension over time. These include:
Low blood pressureSometimes, blood pressure can be lower than normal. Low blood pressure is considered:
Low blood pressure isn't always cause for concern — in fact, it's often harmless, and can even indicate good health. "If you're an athlete, an exerciser, or someone who does a lot of things to take care of their body, it can be normal to have a relatively low blood pressure," says Jordana Cohen, MD, a hypertension expert at Penn Medicine. However, you should check in with your doctor when low blood pressure is accompanied by the following symptoms:
This may be a result of certain conditions or medications. Low blood pressure typically occurs with Parkinson's disease, hormonal changes, and pregnancy. Elevated blood pressureElevated blood pressure is considered:
This is the first warning sign for hypertension — and it's often called pre-hypertension. Your doctor will talk with you about implementing lifestyle changes that can effectively lower blood pressure, including:
Hypertension: Stage 1Hypertension is considered:
Medication is generally not considered necessary to treat hypertension at this level, and you should instead commit to making those healthier lifestyle choices to lower blood pressure, says Cohen. If you have to focus your energy on one blood-pressure-reducing activity, Cohen recommends exercise, as it not only lowers blood pressure on its own, but it can also reduce stress, which is another cause of high blood pressure. Hypertension: Stage 2Hypertension becomes worse when it rises to:
While intensive lifestyle modification to reduce high blood pressure is still necessary, Cohen says medication is also typically required to lower someone's stage 2 hypertension. If left untreated, blood pressure this high can lead to the following health threats:
Hypertensive crisisA hypertensive crisis is considered:
This can be very dangerous and require immediate medical attention, especially if it's combined with the following symptoms:
A hypertensive crisis can result in organ damage, and indicates a heightened risk for stroke, heart attack, and other life-threatening consequences. If you're experiencing blood pressure this high along with any of these symptoms, call 911 immediately. How often should you measure blood pressure?If you have normal blood pressure, and your doctor thinks you're at a low risk for developing hypertension, you'll likely only get your blood pressure measured once a year, at a routine check-up. However, if you're at risk or have hypertension, your doctor may recommend that you check blood pressure at home. If you have a clinician-approved at-home blood pressure measuring kit, you should measure your blood pressure twice in the morning and twice in the evening, waiting a minute between readings, says Cohen. Additionally, she says it's important to calmly wait five minutes before measuring your blood pressure, as it can affect the accuracy of your reading. "If you're checking your blood pressure when you're exercising, moving around, or without taking that five minute break, then it's just not a useful blood pressure," Cohen says. Cohen recommends using a blood pressure measuring device from an accredited source, such as Validate BP. Devices are independently reviewed by experts associated with the American Heart Association to see which ones provide the best, clinically accurate results. Related stories from Health Reference:
