What is Blood pressure?

The force that propels blood through our circulatory system is referred to as blood pressure.

Without blood pressure, oxygen and nutrients would not be pumped around our circulatory system to nourish our tissues and organs.

Blood pressure is also important because it transports white blood cells, antibodies, and hormones like insulin, all of which are important for immunity.

Two numbers are used to determine blood pressure:

 

The first figure, known as systolic blood pressure, is a measurement of the pressure in your arteries when your heart beats.

The second figure, diastolic blood pressure, refers to the pressure in your arteries while your heart is at rest between beats.

If the measurement was 120 systolic and 80 diastolic, you’d say “120 over 80” or write “120/80 mmHg.”

To be considered normal, blood pressure should be less than 120/80 mmHg.

You have high blood pressure when your blood pressure, or the force of blood flowing through your blood vessels, is consistently too high (also known as High blood ressure or hypertension).

  • A systolic pressure of 130 to 139 mm Hg or a diastolic pressure of 80 to 89 mm Hg is considered stage 1 hypertension.
  • In the second stage of hypertension, the systolic pressure is greater than 140 mm Hg, whereas the diastolic pressure is larger than 90 mm Hg.
  • Hypertensive crisis occurs when systolic pressure exceeds 180 mm Hg and diastolic pressure exceeds 120 mm Hg

A value of less than 90 millimetres of mercury (mm Hg) for the top number (systolic) or 60 mm Hg for the bottom number (diastolic) is considered low blood pressure (diastolic).

Among the symptoms and signs are:

 
  • Dizziness or lightheadedness
  • Convulsing
  • Difficulty seeing or fading vision
  • Emesis
  • Tiredness
  • An inability to focus
