Normal Blood Pressure by Age

Blood pressure is recorded as two numbers: systolic (the pressure when the heart beats) over diastolic (the pressure when the heart rests between beats).

Blood Pressure Categories for Adults

• Normal: below 120/80 mmHg
• Elevated: systolic 120–129 and diastolic below 80
• High blood pressure (Stage 1): systolic 130–139 or diastolic 80–89
• High blood pressure (Stage 2): systolic 140 or higher, or diastolic 90 or higher
• Hypertensive crisis: systolic higher than 180 and/or diastolic higher than 120 — this requires immediate medical attention

These categories apply broadly across adulthood rather than having separate official ranges for every age group.

How Blood Pressure Tends to Shift With Age

Blood pressure, particularly systolic pressure, tends to rise gradually with age as arteries naturally become less flexible over time. This is common, but "common" doesn't mean risk-free — the same diagnostic categories above still apply, and higher readings still carry the same long-term risks regardless of age. This age-related stiffening can also produce isolated systolic hypertension — a pattern common after age 60 where systolic pressure is elevated while diastolic pressure stays in the normal range. It's diagnosed and managed using the same categories above and carries the same cardiovascular risks as other forms of high blood pressure.

Why One Reading Isn't the Full Picture

A single elevated reading can reflect stress, caffeine, or the "white coat effect" of being in a clinical setting. Diagnosis of high blood pressure is typically based on multiple readings over time, sometimes including home monitoring.
