High blood pressure, or hypertension, is generally considered too high when the systolic pressure (the top number) is 130 mm Hg or higher, or the diastolic pressure (the bottom number) is 80 mm Hg or higher
. Blood pressure categories according to the American College of Cardiology and the American Heart Association are:
- Normal: Less than 120/80 mm Hg
- Elevated: Systolic 120-129 mm Hg and diastolic less than 80 mm Hg
- Stage 1 Hypertension: Systolic 130-139 mm Hg or diastolic 80-89 mm Hg
- Stage 2 Hypertension: Systolic 140 mm Hg or higher or diastolic 90 mm Hg or higher
A blood pressure reading higher than 180/120 mm Hg is considered a hypertensive crisis, which is a medical emergency requiring immediate attention
. Untreated high blood pressure increases the risk of heart attack, stroke, and other serious health problems. Regular monitoring and lifestyle changes or medication are important to manage high blood pressure effectively
