READING LOOKUP

Blood pressure 124 over 50 to 109

A top number of 124 is in the Elevated range. The bottom number decides the rest: under 80 stays Elevated, 80 to 89 is Stage 1, and 90 or higher is Stage 2.

124/80 to 89: Stage 1 hypertension
124/90 to 109: Stage 2 hypertension

Every 124 reading

Pulse pressure is the top number minus the bottom number. MAP (mean arterial pressure) is the bottom number plus a third of the pulse pressure.

What to do with a 124 reading

Keep checking now and then, the same way each time. Your category comes from the average of many home readings, so one number tells you less than a week of them.

With a bottom number of 80 or higher, the reading is at or above 130/80. In that case: sit quietly for 5 minutes and take two readings a minute apart. If home readings average in this range over a week, share them with your doctor, who will look at them alongside your overall heart risk.

Readings move from minute to minute, and the first one usually runs a few points higher. The home measuring guide covers how to get a reading you can trust, and the 7-day home average turns a week of readings into the number your doctor uses. To check any reading, use the category checker.
