I just did a 24 hour blood pressure check. I am a 5' 3", 55 y.o white female and active (run, bike, tennis etc), and am approx 10-15 lbs overweight (according to me!) and in good health. The BP results were gave an avg of 132/76. It appears this is a high normal, correct? I should be able to reduce my systolic by diet and exercise, and avoid medication, correct?
