<s>[INST] I am a healthy 69 year old female and was in my Drs office today for my wellness exam and my blood pressure was high for me. It is usually 129/64. Today it was taken 3 times. 155/84, then 162/65, then 141/58. What could cause that jump in a year. The nurse practitioner didn t seem too alarmed but she wouldn t let me leave until it came down to the final reading [/INST] hi. Good to see your concern about your health. So far as your question is concerned, with the information provided there may be  many causes of increased blood pressure with most important being the age itself. Moreover, additional environmental and psychological conditions like exertion or anxiety may increase the blood pressure momentarily. That may be the scenerio in your case while ariving to the physician office you might have had a walk or may be gone upstairs. Additionally in such a settings, a little bit of anxiety may also be there. In such conditions i advise my clients to record their B.P twice daily for atleast a week. then come up with the B.P record to the physician for appropriate further action as a single reading or few readings taken in a short while is not the indication for antihypertensive therapy unless its to high that it necessitates urgent action. I hope these words might help to better understand your health status.Wishing you the best of health.Regards. </s>
