It was elevated BP reading that led to blood tests (because of the potential implications for kidney health) that led to my diagnosis. Although my BP was elevated at diagnosis, it wasn't as bad as the diagnostic readings suggested as my own monitoring demonstrated a nice profile for White Coat Syndrome (WCS).
As I got my blood results into the zone, and trimmed up, my blood pressure fell back too, and these days I normally run about 100-110/65-75, depending on what I'm up to.
WCS is still a bit of a pain though, as on a recent pre-op assessment my reading was elevated, but not by as much as on admission when it was something like 210/110. Allegedly, they don't operate over 200/100, but when I talked it through with the anaesthetist he reckoned the best approach was to just get me to sleep and let them get on with it. (Phew)
Your own readings could be informative, but otherwise do you have any trimming up to do, and how are your blood scores?
Erm,........ Obviously telling you not to be stressed wouldn't be helpful as that's not a voluntary thing, usually.
