This pressure — blood pressure — is the result of two forces: The first force systolic pressure occurs as blood pumps out of the heart and into the arteries that are part of the circulatory system. The second force diastolic pressure is created as the heart rests between heart beats.
These two forces are each represented by numbers in a blood pressure reading. See how high blood pressure can damage your arteries and heart. The primary way that high blood pressure causes harm is by increasing the workload of the heart and blood vessels — making them work harder and less efficiently.
Over time, the force and friction of high blood pressure damages the delicate tissues inside the arteries. In turn, LDL bad cholesterol forms plaque along tiny tears in the artery walls, signifying the start of atherosclerosis. The more the plaque and damage increases, the narrower smaller the insides of the arteries become — raising blood pressure and starting a vicious circle that further harms your arteries, heart and the rest of your body.
High blood pressure usually has no warning signs or symptoms, and many people do not know they have it. 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.
Adults with diabetes, high blood pressure, or both have a higher risk of developing chronic kidney disease than those without these conditions. Measuring your blood pressure is quick and painless. Talk with your health care team about regularly measuring your blood pressure at home, also called self-measured blood pressure SMBP monitoring.
Many people with high blood pressure can lower their blood pressure into a healthy range or keep their numbers in a healthy range by making lifestyle changes. Talk with your health care team about. Both the systolic and diastolic pressures are recorded as "mm Hg" millimeters of mercury. This recording represents how high the mercury column in the blood pressure cuff is raised by the pressure of the blood.
Blood pressure is measured with a blood pressure cuff and stethoscope by a nurse or other healthcare provider. You can also take your own blood pressure with an electronic blood pressure monitor. These are available at most pharmacies. Use these numbers as a guide only. A single elevated blood pressure measurement is not necessarily an indication of a problem. Your healthcare provider will want to see multiple blood pressure measurements over several days or weeks before making a diagnosis of high blood pressure and starting treatment.
People in their early to middle adult years; men in this age group have higher blood pressure more often than women in this age group.
