For example: 122/76 (122 over 76); systolic = 122, diastolic = 76. Blood pressure of less than 140 over 90 is considered a normal reading for adults. A systolic pressure of 130 to 139 or a diastolic pressure of 85 to 89 needs to be watched carefully. A blood pressure reading equal to or greater than 140 (systolic) over 90 (diastolic) is considered elevated (high).In some people, the system that regulates blood pressure goes awry: arteries throughout the body stay constricted, driving up the pressure in the larger blood vessels. Sustained high blood pressure - above 140/90 mm Hg, according to most experts - is called hypertension.
About 90 percent of all people with high blood pressure have "essential" hypertension - meaning that it has no identifiable cause. In the remaining 10 percent of cases, the elevated blood pressure is due to kidney disease, diabetes, or another disorder. |
