B12d and Cortisol?

After a B12D diagnosis, mid December 2016, following a number of blood tests due to having "classic" B12 deficiency symptoms including big neurological one's, but apparently no anaemia, I was started on the usual loading phase followed by weekly B12 injections, which I have had now for the last 12 weeks, plus numerous additional blood tests.

My GP has just sent me a message via his secretary, that he wants me to have yet another blood test, specifically to test my Cortisol levels. Having been reading this site regularly since I was first diagnosed, I do not recall anyone ever having mentioned Cortisol levels or testing.......can anyone enlighten me as to why this would be requested and the likely reason for it please.

Thanks for the link - I haven't visited this site for a very long time and it's really improved - very useful and simply expressed explanations. Lots of questions answered on the first page. Personally, the info about the pituitary really struck a chord, as when I first met my current GP he said he thought I had nervous system/pituitary damage but he didn't know why and there was no treatment. According to the info on the site, low B12 damages the pituitary.


I don't trust anything from that site. Never have. It is full of such dodgy gems as -

the heart is a big bundle of a special sort of muscle which is also nerve


lack of references is a bit frustrating but not a lot of time to research other info
