The normal blood pressure for a healthy adult is generally considered to be less than 120 mmHg systolic (the upper number) and less than 80 mmHg diastolic (the lower number), often written as "120/80 mmHg" or lower
. More specifically:
- Normal blood pressure is below 120/80 mmHg.
- Elevated blood pressure is systolic between 120-129 mmHg with diastolic less than 80 mmHg.
- High blood pressure (hypertension) stage 1 is systolic 130-139 mmHg or diastolic 80-89 mmHg.
- Hypertension stage 2 is systolic 140 mmHg or higher or diastolic 90 mmHg or higher.
- A hypertensive crisis is when systolic is higher than 180 mmHg and/or diastolic is higher than 120 mmHg, requiring immediate medical attention
Normal blood pressure can vary slightly by age and gender but generally remains under 120/80 mmHg for adults
. In summary, the widely accepted normal blood pressure range is less than 120/80 mmHg. Readings consistently above this range may indicate elevated or high blood pressure, which should be managed under medical guidance
