For clarification sake: Is prehypertensive 140/90 or 139/89?

In nih.gov site, it specifically said norm is %26lt;120/80
prehypertensive is 120/80-139/89
hypertensive is %26gt; or equal to 140/90I've asked this question previously... why so many different and inconsistent replies? Thanks.
Answer:
The NIH.gov site has the ranges correct, so technically 139/89 is prehypertensive and 140/90 is hypertensive (stage 1). In general, the lower the blood pressure, the better (provided it doesn't get too low), which is why you've gotten so many different replies. It'd be healthier if someone could get their blood pressure less than 120/80 if possible, even though 120/80 isn't technically 'hypertensive.'Another thing one should know about blood pressure, is that it varies throughout the day. It is not a constant value--it fluctuates based on what you are doing and your mood. Thus, if you get a measurement of 139/89, it is so close to hypertensive, that a doctor may find that more concerning than a value of 121/81 (though both values are technically 'pre-hypertensive').

Borderline hypertensive is 140/90. The reason so many inconsistent replies is that the numbers are just a guide line. Some people can have slightly higher numbers and it can be normal for them. The best way to get your systolic and diastolic number down is: if you smoke, quit; if you eat junk food (fats and fried food), quit; exercise regularly and practice ways to keep you calm and balanced, like yoga and meditation and deep breathing.

Whar is all this prehypertension and prediabetes. This term is meaningless, since under different conditions BP can vary considerably. There is no prehypertension.
