For adults (aged 18 or over) the WHO categorized the DBP in 5 levels:
(values in mmHg)
Severe Hypertension
>110
Moderate Hypertension
100-109
Mild Hypertension
90-99
High Normal Blood Pressure
85-89
Normal Blood Pressure
<85
If your DBP falls within the “normal” range (<90), it is still possible to have high systotic blood
pressure. The WHO categorized blood pressure by the systolic level:

with note of past readings and the patient’s present medical condition.
