If a significant part of this mechanism relies on re-absorption from bile that would be an issue due to lack of intrinsic factor breaking the "enterohepatic recirculation"

Chronic conditions impacting absorption include atrophic gastritis or pernicious anaemia, where there is a lack of intrinsic factor, a protein essential for the uptake of B12 in the digestive tract
