Normal blood pressure is considered less than 120 mmHg systolic and less than 80 mmHg diastolic (written as 120/80 mmHg).

Stage 1 Hypertension is when systolic is 130-139 mmHg or diastolic is 80-89 mmHg. Lifestyle changes and possibly medication may be recommended.

A hypertensive crisis (systolic over 180 and/or diastolic over 120) requires immediate medical attention, especially if accompanied by symptoms.

For most adults, checking blood pressure at least once a year is recommended. Those with high blood pressure may need to check more frequently.

Readings can be affected by stress, caffeine, exercise, full bladder, smoking, time of day, and position during measurement.
