What is the optimal range for blood pressure levels?

Less than 120/80: Normal blood pressure (BP) is less than 120/80 for all adults. While we don't treat most unless repeated BP greater than 140/90, we won't treat elderly (older than 60yo) until greater than 150/90 on 2 or more occasions. With that said, recent studies show no benefit to driving BP down below 120/80. Instead, taking enough meds to drop below 140/90 (or 150/90 if older) is fine. Don't forget lifestyl ...Read more

Is 120/90 a good blood pressure level for a 48 year old man? What does the 9 represent? Thank you.

Diastolic HTN: 120 is excellent. But the 90 needs to be worked on. It indicates that your diastolic blood pressure is high which means your heart is working against more pressure than it would like to. Minimize salt, try dash diet, exercise, lose weight, don't smoke, and avoid stress and you may be able to get it to around 80 millimeters of mercury where it should be. Good luck to you. ...Read more
