What is Hypertension?

Normal blood pressure. Your blood pressure is normal if it’s below 120/80 mm Hg. Elevated blood pressure. Elevated blood pressure is a systolic pressure ranging from 120 to 129 mm Hg and a diastolic pressure below (not above) 80 mm Hg. Elevated blood pressure tends to get worse over time unless steps are taken to control blood pressure. Elevated blood pressure may also be called prehypertension. Stage 1 hypertension. Stage 1 hypertension is a systolic pressure ranging from 130 to 139 mm Hg or a diastolic pressure ranging from 80 to 89 mm Hg. Stage 2 hypertension. More-severe hypertension, stage 2 hypertension is a systolic pressure of 140 mm Hg or higher or a diastolic pressure of 90 mm Hg or higher. Hypertensive crisis. A blood pressure measurement higher than 180/120 mm Hg is an emergency that requires urgent medical care. If you get this result when you take your blood pressure at home, wait five minutes and retest. If your blood pressure is still this high, contact your doctor immediately. If you also have chest pain, vision problems, numbness, or weakness, breathing difficulty, or any other signs and symptoms of a stroke or heart attack, call emergency. Both numbers in a blood pressure reading are important. But after age 50, Green the systolic reading is even more important. Isolated systolic hypertension is a condition in which the diastolic pressure is normal (less than 80 mm Hg) but systolic pressure is high (greater than or equal to 130 mm Hg). This is a common type of high blood pressure among people older than 65. Because blood pressure normally varies during the day and may increase during a doctor visit (white coat hypertension), your will likely be requested to take several blood pressure readings at three or more separate appointments before diagnosing you with high blood.
