What is normal blood pressure by age

Q.I take medication for hypertension and monitor my own blood pressure. But it seems what is considered normal keeps changing. What numbers do you advise?

A. The most recent guidelines use a reading of less than 120/80 mm Hg as normal (see below).

But that is not some magical number to guide what an individual person should strive for. Instead, it's best to consider the right range of blood pressure that best fits your personal circumstances, with a general goal of striving for lowest acceptable top and bottom numbers.

So the big question is: What is acceptable?

No one size fits all. It depends upon many factors, including the presence of other chronic conditions, such as heart disease or kidney disease. For example, if you have coronary artery disease, you don't want your diastolic pressure (the bottom number) to be less than 50 to 55 mm Hg.
