Hi Lynda07
Here is what it says on this website about HRT and hypertension:
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.
You should be fine with transdermal oestrogen but if it is borderline high then I presume you are taking steps to reduce it naturally anyway eg re body weight, exercise, salt, smoking, alcohol, diet - if necessary that is!? Not sure whether the norethisterone (the progestogen) has any effect? Sounds like it could be due to anxiety but important to monitor anyway as you are doing.
