Hypertension: Frequently Asked Questions
December 18, 2007 |
Answers to your frequently asked questions about hypertension, commonly called high blood pressure.
1. What Causes Hypertension?
While the cause of hypertension in most people remains unclear, a variety of conditions — such as getting little or no exercise, poor diet, obesity, older age, and genetics — can lead to hypertension.
2. What Is Systolic and Diastolic Blood Pressure?
The blood pressure reading is measured in millimeters of mercury (mm Hg) and is written as systolic pressure, the force of the blood against the artery walls as your heart beats, over diastolic pressure, the blood pressure between heartbeats. For example, a blood pressure reading is written as 120/80 mm Hg, or "120 over 80". The systolic pressure is 120 and the diastolic pressure is 80. Hypertension - frequently asked questions - WebMD
