Question

if your patient presents with low intrinsic factor what deficiency is most likely? a) b6 b) b9 c) b12 d) iron

Explanation:

Intrinsic factor is essential for the absorption of vitamin B12 in the ileum. A deficiency in intrinsic factor leads to impaired B12 absorption. Vitamin B6 (pyridoxine) has different functions (e.g., neurotransmitter synthesis). Vitamin B9 (folic acid) absorption is not directly dependent on intrinsic factor. Iron absorption has its own mechanisms (e.g., regulated by hepcidin) and is not related to intrinsic factor.

Answer:

c) B12
