My blood pressure was 160 over 90 yesterday morning and last night was 164 over 80 then 125 over 78 and then this morning it is 131 over 75. Can caffeine or anxiety cause to shoot up like it did yesterday? (Had two espressos on an empty stomach in the AM which I never do.) I was also in an oral surgeon's office for the first reading. I am 5'7", 126 lbs. female, mid fifties, eat low salt diet, no red meat, exercise and drink lots of water and normally, green tea.
