Reading the Two Numbers
Systolic (upper) is the pressure while the heart beats; diastolic (lower) while it rests. Per the American Heart Association: Normal <120/<80 · Elevated 120-129 and <80 · Stage 1 hypertension 130-139 or 80-89 · Stage 2 ≥140 or ≥90 · Crisis >180 and/or >120 (seek care immediately). European (ESC) cutoffs run slightly higher — 140/90 for hypertension — which is why your doctor's wording may differ.
Measure seated, rested for 5 minutes, arm at heart level, no caffeine or smoking for 30 minutes prior; take 2-3 readings and average. A single high reading is not a diagnosis — patterns over days matter, and only a clinician can diagnose hypertension.
Frequently Asked Questions
My two numbers fall into different categories — which counts?
The higher category wins. 125/85 is Stage 1 (because of the 85), not Elevated.
Is 90/60 too low?
Below 90/60 is generally called hypotension. If you feel fine it is often harmless, but with dizziness or fainting it deserves a medical check.
Why does my home reading differ from the clinic?
"White coat" effect can add 10-20 mmHg at the clinic; the reverse (masked hypertension) also exists. Home averages taken properly are considered highly informative by guidelines.
