I think the standard is still 140/90 to be classified as hypertensive.
The 120-139/80-89 category is called "prehypertensive" and means one should keep an eye on their blood pressure and make lifestyle changes to try to reduce the numbers.
The new optimum is to have blood pressure under 120/80.
Many doctors will try to medicate you if you are in the 120-139/80-89 range, but this is still considered OK pressure, and I would resist attempts to medicate in this range. I would seriously try to make some lifestyle changes like reduce salt, better diet, lose weight and get exercise in this range.
Someone correct me if I am wrong on these facts.
I wish someone had told me about the "prehypertensive category" and what I should do. I might have tried to lose my extra 35 pounds and start exercising earlier. Who knows if it would have made a difference, but I am in medication land now, and weight loss and exercise doesn't seem to be able to change that.
