What does the blood pressure reading 130/90 mean? Is this a healthy blood pressure or not?
Lorico [155]

Answer with Explanation:

High Blood Pressure refers to a condition wherein the heart is pumping more blood, thus causing a narrowing of the arteries. Such narrowing of arteries causes the pressure of blood to increase.

A person's blood pressure is dependent on the "systole" and "diastole" of the person. The "systole" is the pressure on top of the reading and is caused by the contraction of the ventricles (between the first and second heart sounds). The "diastole" refers to the relaxation of the muscles.

Depending on your health condition and age, a blood pressure reading of 130/90 may be normal or abnormal. For example, if you have a kidney disease, your blood pressure may be elevated than normal. So, this makes 130/90 a normal blood pressure for you. However, if your normal blood pressure is 120/80 then you suddenly get 130/90, then it means this is abnormal for you. There are probably factors, such as eating salt foods that contributed to this.

<u>Normal blood pressure is 120/80 and less than 140/90.</u> Thus, we can consider 130/90 as a healthy blood pressure. Those blood pressure lower than this may also be acceptable. Remember that when you are getting older, your blood pressure is increasing because the arteries in your body is changing regarding its structures.
