Hi
Mine was always low even taking the combined pill, post-meno and on HRT and over the last year or so it's been up and down. One 6 monthly reading was back to normal, the next one higher (partly because I was running late and in traffic on the way!) but then the last reading a few weeks ago was high again. Doc doesn't seem too worried at the moment. Said to cut salt which I do because I hate it and salty foods, I try to exercise more and have always watched what I eat so it's a tad frustrating! So I think there is a link, Doc said sometimes no matter what you do it can be in the genes that it rises as you get older.
