A member asked:
If you have autoimmune atrophic gastritis or pernicious anemia, can your b12 levels fluctuate between low and low-normal(like 201)? or if you have either of those diseases will your b12 always be low until you start b12 injections?
A doctor has provided 1 answer
Regardless of the cause of your low B-12 levels, you need to supplement to return to a normal serum range, to avoid neurological complications. The most efficient and rapid approach involves monthly injections.
