I was recently diagnosed with pernicious Annemia. My initial B12 level was too low to read on the blood analysis system used.
I received 4 injections in a week and my level rose to ~260. I thne began receiving injections every tow weeks for the last several months and my level does not rais above ~225.
Has this happened to others? Do i need a bigger dose (I assume there is "normal" dose?)or a dose more frequently? Seems odd that the level won't raise much above 200. Could this be an indication of some other issue?
