A blood pressure reading features two numbers: a top number, which is called systolic blood pressure, and a bottom number, which is called diastolic blood pressure. Systolic blood pressure measures how much pressure your blood exerts against your artery walls. When the heart contracts, it pumps extra blood into the circulatory system, increasing the pressure.
That increase is measured by systolic blood pressure. Zocdoc helps you find and book top-rated doctors, on demand. Visit them in their offices, or video chat with them from home. Diastolic pressure then measures the pressure within the system when the heart is at rest, says Dr. Systolic blood pressure is the peak pressure during a heartbeat while diastolic blood pressure is the lowest pressure between heartbeats when the heart relaxes briefly.

When it comes to race and ethnicity, Dr. Desai says certain groups have a higher rate of hypertension. There are five blood pressure stages: normal and four specific stages of hypertension, which range from very treatable to urgent. People with a blood pressure range of 90 to systolic and 60 to 80 diastolic have normal blood pressure, says Dr.
A systolic reading below 90 signifies low blood pressure. A blood pressure reading of to systolic and less than 80 diastolic signifies elevated blood pressure and, thus, a higher probability of developing hypertension. It also results in [the] micro-tearing of the artery wall, leading to cholesterol deposition atherosclerosis.
This leads to [the] narrowing of the vessel and further elevation of blood pressure. Hypertension Stage I is defined by a systolic reading of to and a diastolic reading of 80 to Wong says while doctors initially treat this stage of hypertension by suggesting a healthier lifestyle—eating more vegetables and whole grains, using less salt, increasing physical activity and controlling stress—medications may be needed if blood pressure falls in this range on multiple readings over a period of time in people with other cardiovascular risk factors.
Risk factors for atherosclerosis may include high cholesterol and triglyceride levels, high blood pressure, smoking, diabetes, obesity, physical activity and eating saturated fats. Hypertension Stage II is marked by a systolic reading of at least and diastolic reading of at least Still, this stage of hypertension is more serious than the former and should be watched carefully. A hypertensive crisis is an emergency situation and occurs when the systolic blood pressure reading exceeds and the diastolic reading exceeds Gain portability without compromising accuracy.

It develops over time and often happens as a result of unhealthy lifestyle choices, according to the Centers for Disease Control and Prevention CDC.

Elevated Elevated blood pressure is when readings consistently range from systolic and less than 80 mm Hg diastolic. Hypertension Stage 1 Hypertension Stage 1 is when blood pressure consistently ranges from systolic or mm Hg diastolic.
Hypertensive crisis This stage of high blood pressure requires medical attention. Prescription for Success Your donation funds research, education and advocacy efforts that are saving lives every day. Measuring your blood pressure is the only way to know whether you have high blood pressure.
High blood pressure usually develops over time. It can happen because of unhealthy lifestyle choices, such as not getting enough regular physical activity. Certain health conditions , such as diabetes and having obesity, can also increase the risk for developing high blood pressure.
High blood pressure can also happen during pregnancy. You can manage your blood pressure to lower your risk for serious health problems that may affect your heart, brain, kidneys, and eyes. High blood pressure can damage your health in many ways. It can seriously hurt important organs like your heart, brain, kidneys, and eyes. The good news is that, in most cases, you can manage your blood pressure to lower your risk for serious health problems.
High blood pressure can damage your arteries by making them less elastic, which decreases the flow of blood and oxygen to your heart and leads to heart disease. In addition, decreased blood flow to the heart can cause:. High blood pressure can cause the arteries that supply blood and oxygen to the brain to burst or be blocked, causing a stroke.
Brain cells die during a stroke because they do not get enough oxygen. Stroke can cause serious disabilities in speech, movement, and other basic activities. A stroke can also kill you. Having high blood pressure, especially in midlife, is linked to having poorer cognitive function and dementia later in life. This is the diastolic pressure. Diastolic blood pressure can increase with age as a result of stiffening arteries. Blood pressure BP readings are expressed as a ratio of the systolic pressure the first number or numerator , over the diastolic pressure the second number or denominator.
When systolic and diastolic blood pressures fall into different categories, the higher category should be used to classify blood pressure level. You can measure your own blood pressure at home with a digital blood pressure device that can be purchased at most pharmacies.
