Moderate hypertension: ≥ 140/90 mmHg
Excessively low blood pressure: ≤ 90/60 mmHg
A single reading is not sufficient: the trend is observed over several days.
Why does blood pressure rise with age?
Arteries become less flexible.
The heart must pump harder.
Natural regulation is less effective.
After age 60, slightly higher blood pressure is often tolerated if other risk factors are not present.
