Thank you very much I will check and ask if 24 hour monitoring is available for me in NZ too.
Yes, that's possible.
What you should do, is asking your doctor for a 24 hour blood pressure monitoring, which will give a more correct picture of your blood pressure and how it changes when you are anxious, calm, asleep, etc.
The focus on how important normal blood pressure is, and how dangerous high blood pressure is, can make anyone anxious and produce false blood pressure results. And 149/80 is just mildly elevated. Anxiety will make the blood pressure increase in everyone. It's a normal response.
In Norway, almost no one get the diagnosis of high blood pressure without a 24 hour monitoring, to reveal the true blood pressure.
