How high is high blood pressure?

Answer 1

High blood pressure is a blood pressure reading of 140/90 mmHg or higher. Both numbers are important.

A blood pressure reading below 120/80 mmHg is considered normal. In general, lower is better. However, very low blood pressure can sometimes be a cause for concern and should be checked out by a doctor.

Doctors classify blood pressures under 140/90 mmHg as either normal or prehypertension.

Normal blood pressure is lower than 120/80 mmHg.
Prehypertension is blood pressure between 120 and 139 for the top number, or between 80 and 89 for the bottom number. For example, blood pressure readings of 138/82, 128/89, or 130/86 are all in the prehypertension range. If your blood pressure is in the prehypertension range, it is more likely that you will end up with high blood pressure unless you take action to prevent it.

Answer 2

high blood pressure - blood pressure higher than 140/90

by the way:
optimal : <120/<80
normal : <130/<85
high normal : 130-140/85-90

usually, it is taken that normal young adult should have the bp to be 110/75 and for 60 years and above they could be 130/90. typical blood pressure : 120/80

Answer 3

If the top number is over 140 and the bottom number is 90 you are starting to get into high blood preasure. The "normal" or ideal blood preasure is 120/80. I wouldn't worry until this rises to over 140/90. Then it is starting to get to the point where you need to see your doctor.

Answer 4

Usually anything over 120/80-Bottom number is more important
