Weight?? BMI? Any family history of HTN?

Hi. Since you have multiple readings which are more than 120/80 but less than 140/90, we call it as pre-hypertension. At your age of 25 years we do not expect high BP, hence if detected other secondary causes need to be ruled out. First these values need to be taken in a proper way, calm rested state (after 10 min of resting) not while talking or watching TV or just after some activity argument emotional stress.If most values are above 120/80but less than 140/90 you can do lifestyle modification. Like balanced low salt diet, regular exercise, relaxing techniques If majority of the values are more than 140/90 then you should get evaluated to rule out secondary causes of hypertension (kidney causes or certain hormone secreting lesions etc) A BP of 140/90 should not cause fainting dizziness. If you haveepisodes like that get yourself evaluated.
