What does my blood pressure mean?

Enter your reading to see which category it falls into, based on the 2017 American Heart Association / American College of Cardiology guideline for adults.

–

    The categories

    Normal: below 120/80. Elevated: 120 to 129 and below 80. Stage 1: 130 to 139 or 80 to 89. Stage 2: 140 or higher, or 90 or higher. Above 180 and/or above 120 needs attention right away: measure again after 5 minutes and contact your doctor.

    One reading is not a diagnosis

    Blood pressure changes during the day. Your doctor will look at many readings over time, which is why a home log is so useful. This chart is for information only and is not medical advice.

    FAQ

    Good to know.

    What is a normal blood pressure?

    For adults, below 120 systolic (top number) and below 80 diastolic (bottom number) is considered normal in the 2017 AHA/ACC guideline.

    What do the top and bottom numbers mean?

    The top number (systolic) is the pressure when your heart beats. The bottom number (diastolic) is the pressure between beats. Both are measured in mmHg.

    Which number counts if they fall in different categories?

    The higher category counts. For example, 125/82 is stage 1, because the bottom number is 80 or higher.

    How should I measure at home?

    Sit quietly for 5 minutes with your feet flat and your arm supported at heart level. Avoid coffee, exercise and smoking for 30 minutes before. Take two readings a minute apart.
