High Blood Pressure
High blood pressure is abnormally high blood pressure with no known cause. Blood pressure measurements are read as two numbers:
- Systolic pressure: higher number, normal reading is 120 millimeters of mercury (mmHg) or less
- Diastolic pressure: lower number, normal reading is 80 mmHg or less
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.
High blood pressure puts stress on the heart, lungs, brain, kidneys, and blood vessels. Over time, this condition can damage these organs and tissues.
