Its sorta blows people’s minds when they hear I have hypertension because I look like I’m in shape.
That’s just cause they don’t know what they are on about.
How old are you? Hows the diet and what is the diet?
Do you smoke? drink alcohol? Drink coffee? Use prescription drugs of any sort? rec. drugs?
As someone else asked, how many/how long have you been following this? A heavy session at the gym will significantly raise BP for a while afterwards.
You have a family history and that sadly is likely all that you need to have high BP i’m afraid (as this could simply be a genetic predisposition for thicker than average artery walls or whatever).
TBH, i am not sure what you are asking - if you are asking if it is normal for someone to lead a healthy lifestyle and still have high BP… then the answer is yes. It happens.
The best you can do to control it is exactly as your doc (will have i’m sure,) suggested - low sodium, increase cardiovascular exercise to at least 20mins 5x/week, watch dietary fat intake, don’t smoke and limit alcohol, all the normal crap for high BP!
