Hi kazzy123
Sorry to hear you are feeling rough at the moment and without HRT.
Great link from Taz about the effects of diet, body weight and exercise on blood pressure.
Also, this is what it says on this site about high blood pressure and HRT:
Hypertension
Blood pressure should be measured and, if high, should be controlled prior to starting HRT. Blood pressure measurement should be repeated 3 months after starting HRT and is then usually checked at annual review. There is a very small risk of conjugated equine estrogens causing a rise in blood pressure which resolves on cessation of treatment. In the presence of controlled hypertension, HRT is unlikely to worsen control; some recommend using transdermal (patch or gel) HRT.
Sage should be used with caution if hypertensive and St.John's Wort should be used with caution if taking antihypertensive therapy.
How old are you/how long since menopause and what type of HRT were you on?
