Understanding Normal Blood Pressure (Systolic, Diastolic)


What Is Normal BP? 

Do you feel dizzy and lightheaded after waking up, have problems viewing things due to blurred vision, or sometimes your nose bleeds, or you go through constant headaches and blackouts? If that’s the case, you might be dealing with abnormal blood pressure (BP). Trust us, and please don’t ignore these signs. Our body shows certain signs or symptoms when something is not right internally or externally in the body. If you are experiencing any of the above-mentioned symptoms, it’s wise to analyze your body and consult a doctor.  

Blood pressure (BP) is the pressure of blood circulation from the heart to the entire body. The Average blood pressure differs for different sex, and it tends to rise with age. You need to understand how blood pressure affects your health and how to combat those challenges. According to the American Heart Association, normal blood pressure for adults (ages 20 and older) is less than 120/80 mm Hg. 

Normal BP Range For Women 

Do you know high blood pressure is sometimes referred to as a ‘silent condition’ in women? Women dealing with high blood pressure may not experience any high BP symptoms whatsoever, which is why the name ‘silent condition’. Often time’s symptoms don’t appear until the condition has become severe or when the elevated blood pressure has damaged the blood vessels to break. These symptoms include red spots in front of the eyes, dizziness, and skin flushing. Women aged 21-25 have the lowest normal diastolic reading (115.5-70.5), while women aged 31-35 have the lowest normal systolic reading (110.5/72.5). The age group with the highest normal blood pressure reading in women is between ages 56 and 60 (132.5/78.5). 

 Normal Bp Range For Men 

The average BP range for men varies by age group. The age group with the lowest normal blood pressure reading in men is 31-35 years (114.5/75.5). The age group with the highest normal blood pressure level reading in men is 61-65 years (143.5/76.5).  

Here are a few healthy tips for keeping your blood pressure in the normal range:- 

Blood Pressure Stages 

Blood pressure for adults is divided into stages. At each stage, there is a greater risk to your health and body. These stages vary from normal, elevated to high blood pressure conditions. A hypertensive crisis, which is measured at 180/120, is a sharp increase in blood pressure that may cause a stroke. 

Stages of High Blood Pressure:  

  Range of Systolic blood pressure  Range of Diastolic blood pressure 
Elevated  120-129 mm Hg  Less than 80 
Stage 1 Hypertension  130-139 mm Hg  80-89 mm Hg 
Stage 2 Hypertension  140 mm Hg and up  90 mm Hg and up 
Hypertensive crisis  180 mm Hg and up  120 mm Hg and up

Low Blood Pressure Range 

With lack of concentration, fatigue, nausea, blurred vision, fainting, and dizziness as symptoms, low blood pressure is caused by heat exhaustion, liver disease, heart failure, excessive medications, pregnancy, or hormonal problems such as under-active thyroid, diabetes, and hypoglycemia. Low blood pressure does not require treatment, although instilling some healthy habits in your day-to-day activities can keep your blood pressure level in normal parameters:

Diastolic Blood Pressure Range  

The heart rests between beats, so it can be reloaded with blood, this pause in between beats for the refilling of blood is known as “Diastole”. A normal diastolic blood pressure range during quiet rest is 80 mmHg or a little below. If you have high blood pressure, the diastolic number is often higher even during quiet rest. A Low diastolic pressure range may be detected with dehydration or with severe bleeding. 

Typical diastolic BP range: 

Blood Pressure Category   Diastolic pressure range mmHg 
Normal   Less than 80 
Elevated   Less than 80 
High blood pressure   80-89 
High blood pressure   90 or higher  
Hypertensive crisis   Higher than 120
