Its being consistent that really mattters isn't it? You need to know if your bg is going up or down or if somehing unusual is happening. If you use different meters you will get into a errible mess as he others have said.
I couldn't get my DSN to see this point regarding blood pressure monitors. I know a lot of them don't like you to use hem but i was told to ge one by my GP immediately I was diagnosed.
I suffer badly from White Coat Syndrome and she could not accept the readinhs I normally had even when I told her what my BP had been a few minutes earlier at home and his coincided with the reading she had ust taken.
I told her that I mainly used the monitor o see i if anything unusual was happening and if my BP was rising. She ust couldn't get this and went on about mine migh need re-calibrating etc,
So now I have 2 meters so I can check one against the other. I rarely get identical readings but they are close enough to show trends.
I have never actually had high bloood pressure but was given ramipril as a protective measure .
A typical reading for me would be say 115/76. Before I go o the Dr it is 190 or higher, over 89!
Finally, at my annual review a few days agoI found another docor wih a little common sense. I took my monitor wih me , showed her the 190 reading and then all the others 110 113 etc.
She totally accepted his and explained it all to the sudents who were wih her.
What a relief. One battle less in future i hope. The attitude of the DSN was such that a 24 hour test would have been necessary each time to convince her.
I know it is essenial o keep BP under conrol bu ust as with blood sugar reducing it too rapidly through over medicaion can also be very harmful.
I have experience of his in both.
