My Blood Pressure is 101/30 - good or bad?

101/30
mmHg
Very low blood pressure
Systolic (upper)101 normal
Diastolic (lower)30 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.

Measure again now

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

A reading this low is far below the usual range. Either the measurement went wrong — a loose cuff, a moving arm, a device error — or your blood pressure may be too low to keep the brain and other organs well supplied. Don't wait to see whether it passes: follow the steps in the box above.

Know your numbers

Mean arterial pressure54 mmHg

The average pressure that keeps your organs supplied — diastolic plus one third of the gap. Low: below 65, the organs can be under-supplied — measure again and follow the guidance for low readings above.

Pulse pressure71 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

  • Could any of my medicines be lowering my blood pressure?
  • Should we check my blood pressure lying down and standing up?
  • Do my symptoms (if any) need tests such as an ECG or blood count?

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.
