What Is Hypertension
Hypertension is the medical name for high blood pressure. It used to be that normal blood pressure was considered 120/80 and high blood pressure wasn’t diagnosed until the blood pressure reached a level of 140/90 or higher.
A lot of health-care workers still use that definition, that they make the point that pressures between 120/80 and 140/90 are less than desirable. Some physicians refer to blood pressures in this range as “pre-hypertension”.
What has changed is the realization that even relatively minor increases in blood pressure (for example a level of 130/85) can have some deleterious effects. Some physicians are even saying that while 120/80 is “normal” a somewhat lower pressure may be optimal. Such physicians like to see their patients blood pressures in a range of 110/75.
