>If you are consistently measuring blood pressure with an unsupported arm, and that gives you an overestimated BP of 6.5 mmHg, that's a potential difference between a systolic BP of 123 and 130, or 133 and 140 Have hypertension due to genetics, can confirm this is *exactly* what happens. Lazy doctors will check your blood pressure incorrectly, declare you have hypertension and ermagerd you need all the meds! Then you worry about hypertension when you return to the doctor, your blood pressure spikes due to nervousness, and ermagerd it's higher and you need more meds. Repeat every visit. If you get your own blood pressure monitor and support your arm properly, you see your actual (lower) blood pressure...and without the added spike from nervousness. If you still need meds, it's at a much lower dose dictated by genetics rather than an ever-increasing dose caused by poor test methodology.
