    Hello ASHOK,

    Don't be surprised that your BP is always changing due to posture, time of day, if and when a Doc is present, when the temperature is different, etc. That is the whole point of your BP. It's designed to adjust as needed depending on your mood, surroundings, stress levels, have you just eaten, etc. Even differences in right and left limb are normal.

    If your BP often seems elevated, and you have some concern about whether you might be hypertensive, you should ask your physician about doing an Ambulatory Blood Pressure Monitoring (ABPM) study. This is designed to capture your BP throughout the day, and night, so that you have a true picture of your BP and how your body is reacting to all the factors mentioned above.

    Great point Kenny,
    Anybody out there who is diagnosed with hypertension based on a single measurement and given meds should fire their MD immediately. -Not only is the true BP variable, but the instruments are also variable, not to mention the environmental factors cited by you.
    Also, shame on the the AMA and CDC for specifying an exact figure for the "normal" blood pressure (e.g., 120/80 or 115/75).
    At the least they should add plus or minus 10 for systolic and 5 for diastolic in the calculation, since no precise single measure can possibly be valid. The notion that, e.g., 121 is pre-hypertensive and 120 is normal, applied to any particular reading, is downright silly.
