In patients who have undergone a gastrectomy, there is a significant reduction in the stomach's ability to produce intrinsic factor, which is crucial for the absorption of Vitamin B12. This can lead to Vitamin B12 deficiency, as intrinsic factor binds to Vitamin B12 and facilitates its absorption in the ileum, a part of the small intestine.
Due to this impaired absorption, it is necessary to provide supplemental Vitamin B12 to maintain adequate levels and prevent deficiencies. Vitamin B12 supplements can be administered orally in higher doses or through injections, bypassing the need for intrinsic factor.
