A protein secreted by the stomach that is necessary for the absorption of vitamin B12?
The protein secreted by the stomach that is necessary for the absorption of vitamin B12 is called intrinsic factor. Intrinsic factor binds to vitamin B12 in the small intestine, allowing for its absorption into the bloodstream. Without intrinsic factor, vitamin B12 cannot be effectively absorbed and can lead to a deficiency.
Why oral administration of vitamin B12 not effective as a treatment of pernicious anemia?
Pernicious anemia is due to a deficiency of a vitamin called intrinsic factor, which is normally produced by cells of the stomach. Intrinsic factor is required for the absorption of vitamin B12, so if intrinsic factor levels are insufficient, vitamin B12 will not be absorbed well. So administration of vitamin B12 will only help treat vitamin B12-deficiency anemia if vitamin B12 can be absorbed, and this can only happen if there are adequate levels of intrinsic factor to begin with. Patients with pernicious anemia do not have adequate intrinsic factor levels, so they will not be helped by vitamin B12 treatment since they can't absorb it well enough.
Can a Vitamin B12 deficiency be connected to something serious like leukemia?
A Vitamin B12 deficiency is not directly linked to leukemia.

However, some symptoms of Vitamin B12 deficiency, such as anemia, fatigue, and weakness, may overlap with symptoms of leukemia, so it is important to consult a healthcare professional for proper evaluation and diagnosis.
