High Blood Pressure - Facts

---

 

	High Blood Pressure Every time your heart beats, it pushes blood out to your entire body. The blood moves through blood vessels called arteries. The term blood pressure refers to how hard the blood is pressing against the walls of your arteries. When your heart contracts, blood is forced out of the heart, and the pressure increases. When your heart relaxes, the pressure decreases. A blood pressure monitor allows you to see the pressure at both points. The higher number is called the systolic pressure, and the lower number is the diastolic pressure. For example, a normal blood pressure is "115 over 70": 115 systolic pressure (heart contracting)/70 diastolic pressure (heart relaxing) What is high blood pressure High blood pressure, or "hypertension," often has no obvious cause, although many factors can contribute. When you have high blood pressure, your blood vessels are too narrow (constricted) or they may have too much blood volume circulating in them. High blood pressure puts an additional strain on blood vessels throughout your body and increases the workload on the heart. What should my numbers be? The chart below shows how blood pressure is classified in adults at least 18 years old. You want your blood pressure reading to be lower than "120 over 80."                                                              Systolic                                 Diastolic Normal                                              Less than 120                       Less than 80 Pre-High blood pressure             120 – 139                                80  - 89 High Blood Pressure – Stage 1     140 – 159                               90 – 99 High Blood Bressure – Stage 2     160 or over                           100 or over It's possible for only ONE of the numbers to be high (the systolic or diastolic). It is particularly important to keep an eye on a high systolic number. Be Cautious Friends! - ALBERT
