Quizplus · Accepted Answer

The presence of pernicious anemia implies a deficiency in cobalamin absorption specifically due to lack of intrinsic factor. Pernicious anemia may also occur in adults following gastrectomy (removal of the stomach) or when the secretory portions of the stomach have been damaged by gastric carcinoma or have been removed surgically. Cobalamin absorption also may be decreased when there is a chronicovergrowth in intestinal bacteria or tapeworm, and the bacteria or parasites utilize the vitamin before intestinal absorption can occur.
