To the best of my knowledge -
High Blood Pressure - Blood pressure of 140/90 or higher is considered high blood pressure. If one or both numbers are usually high, you most likely have blood pressure problem. This is something you want to discuss with your Dr. as perhaps an adjustment in your lifestyle is all you need to bring your BP into the normal range.
I was dx with high BP in my forties and with a bit of medicaiton and some change in my diet - low salt diet - I maintain a normal BP.
