What can blood pressure tell you?
Blood pressure is divided into two values:
– Systolic Blood Pressure is the blood pressure in the blood vessels that occurs when the heart contracts.
– Diastolic Blood Pressure is the pressure in the blood as the heart relaxes.
In Thailand, normal blood pressure is defined as systolic blood pressure of not more than 140 and diastolic pressure of not more than 90.

millimeter of mercury High blood pressure is divided into 3 levels:
– Level 1 upper body exceeds 140 mm Hg or lower body exceeds 90 mm Hg.
– Second degree, upper body exceeds 160 mm Hg or lower body exceeds 100 mm Hg.
– Level 3 upper body over 180 mm Hg or lower body over 110 mm Hg.

However, a single blood pressure measurement cannot conclusively indicate high blood pressure. It is necessary to repeat the measurement 2-3 times and monitor periodically because blood pressure is a number that can easily be affected by many factors such as tiredness, stress or anxiety.
