What is high blood pressure?
High blood pressure is a common disease among older people but it is becoming increasingly younger. It arises when blood pressure in the arteries rises, proportional to each heartbeat.
If the blood pressure is too high, the heart is forced to work harder to meet the blood supply and enough blood to pump throughout the body. Therefore, if the blood pressure rises too high, it is easy to lead to a stroke, accompanied by heart attacks, in addition to kidney damage.
Normal blood pressure level is 120 / 80mmHg. Of which, 120 is the number for systolic blood pressure (maximum blood pressure - the highest pressure in the artery), and 80 is the number for diastolic blood pressure (minimum blood pressure - pressure) lowest in arteries).
When your blood pressure is greater than 120 / 80mmHg - 139 / 89mmHg, it is called prehypertension, and a blood pressure of 140 / 90mmHg or higher is called hypertension.
High blood pressure levels
The level of hypertension
The threshold for diagnosing high blood pressure may fluctuate slightly depending on the different blood pressure measurements. However, based on the blood pressure values obtained after the proper blood pressure measurement performed by health care workers, the blood pressure level is divided into the following levels:
Optimal blood pressure: Systolic blood pressure <120 mmHg and diastolic blood pressure <80 mmHg.
Normal blood pressure: Systolic blood pressure 120 - 129 mmHg and diastolic blood pressure 80 - 84 mmHg.
Prehypertension: Systolic blood pressure 130 - 139 mmHg and diastolic blood pressure 85 - 89 mmHg.
Hypertension 1: Systolic blood pressure 140 - 150 mmHg and diastolic blood pressure 90 - 99 mmHg.
Hypertension level 2: Systolic pressure 160 - 179 mmHg and diastolic pressure 110 - 109 mmHg.
Grade 3 hypertension: systolic blood pressure ≥ 180 mmHg and diastolic blood pressure ≥ 110 mmHg (a life-threatening condition)
Single systolic hypertension: Maximum blood pressure ≥ 140 mmHg and minimum blood pressure <90 mmHg.
In the case of systolic and diastolic blood pressure are not the same classification as above, a higher priority to rank is preferred. Isolated systolic hypertension is also graded according to the fluctuation of systolic blood pressure.
