High blood pressure
is most of the time asymtomatic hence hypertension
needs tobe detected by doctor high BP
runs in family as you have positive family history. A single high recording of BP is not enough but if this is persistently high then some measures like common salt restriction and reduction in weight if you are overweight
,stopage of tobacco/smoking and alcohol ,and regular exercise if you are sedentary if these don't work or you keep high BP drugs are necessary and we have seen they are required for long periods or most of the times life long.
