High blood pressure is abnormally high blood pressure with no known cause. Blood pressure measurements are read as two numbers:
High blood pressure is defined as systolic pressure greater than 140 mmHg and/or diastolic pressure greater than 90 mmHg. You are considered prehypertensive if your systolic blood pressure is between 120-139 mmHg, or your diastolic pressure is between 80- 89 mmHg. Your doctor will recommend monitoring and lifestyle changes.
High blood pressure puts stress on the heart, lungs, brain, kidneys, and blood vessels. Over time, this condition can damage these organs and tissues.
