My Blood Pressure is 149/37 - good or bad?

149/37
mmHg
Stage 2 hypertension
Systolic (upper)149 stage 2
Diastolic (lower)37 low

Each scale rates one number on its own; the higher category counts. Blue = low (systolic under 90 or diastolic under 60) — a common label, not an AHA/ACC category.

If the reading is real and you feel faint, confused, short of breath, or cold and clammy, call 911 (US) or your local emergency number. Otherwise contact a doctor today.

What this reading tells you

This reading is in the stage 2 range. If your average stays here, your arteries are under clearly higher strain than they should be — this is the level where doctors usually start medication alongside lifestyle changes.

Your diastolic number (37) is below 60 — on its own that would count as low — while the other number sets the category, and the gap between the two is wide (112 mmHg). Mention this combination to your doctor. Because the diastolic number is very low, follow the box above.

Know your numbers

Mean arterial pressure74 mmHg

The average pressure that keeps your organs supplied — diastolic plus one third of the gap. Typical — within the usual range of 70–100.

Pulse pressure112 mmHg

Wide. A gap above 60 usually means the large arteries have lost some elasticity — common after 60 and a reason to keep the systolic number in check.

Questions to ask your doctor

  • Which medication do you recommend, and what side effects should I watch for?
  • Should we start with a combination pill?
  • Do I need tests of my kidneys, heart or eyes?
  • How soon should we re-check after starting treatment?

Your 7-day home check

One reading can mislead. Measure twice each morning (before medication and coffee) and evening for a week, skip day 1, and average the rest. Print this log or copy it. How to measure: How to Check Your Blood Pressure at Home.
