I just found out i have b12 deficiency. my b12 level was 169. can someone tell me exactly what this means and what else it can cause. ?

Anemia: Low B12 can come from chronic low dietary intake (vegetarian diet) , pernicious anemia , other GI problems that results in malabsorption, hematologist problems you need to have further evaluation for this but need regular B12 injections frequently to improve the levels. They should check other vitamin levels to make sure they are fine as well.

Try sublingual B12: Agree with dr. Patel's answer. Band, for those who cannot take B12 injections, new studies have shown that a sublingual (under the tongue) dissolving B12 tablet raises B12 levels as well as injections. Both bypass the digestive tract and go straight to the blood stream.
