I have a bit of a mystery with my B12 levels. I do not have pernicious anaemia, but not only can I not increase my B12 levels dietarily, they drop extremely rapidly after injections. A recent example is that a couple of weeks after a course of 3 injections, my level was at about 1400. After just 5 weeks I was down to 250, and feeling ill from it. I have been down to 80 in the past as well (have been deficient on and off for 2 years now). This really rapid drop has happened twice now, and is really affecting my health. I have seen a haematologist who appeared unconcerned, but offered no explanation as my haematocrit (sp?) was normal. My GP is stumped, she has never seen it in 30 years. I am concerned as I have been ill (with undiagnosed celiac) for a long time, I am working really hard to get my health back, but I can't seem to get this under control. If someone with pernicious anaemia can get by on 1 injection every 3 months, why should I need to have them all the time?
Any thoughts would be much appreciated.
Confused and anaemic!
