<p><b>New page</b></p><div>Vitamin B<sub>12</sub> deficiencies have a greater effect on the pregnant, young children, and elderly people, and are more common in middle and lower developed countries due to malnutrition. The most common cause of vitamin B<sub>12</sub> deficiency in developed countries is [[malabsorption|impaired absorption]] due to a loss of [[Intrinsic factor|gastric intrinsic factor]] (IF) which must be bound to a food-source of B<sub>12</sub> in order for absorption to occur. A second major cause is an age-related decline in [[Gastric acid|stomach acid]] production ([[achlorhydria]]), because acid exposure frees protein-bound vitamin. For the same reason, people on long-term antacid therapy, using [[proton-pump inhibitors]], [[H2 blocker|H<sub>2</sub> blockers]] or other antacids are at increased risk.</div>FuzzyBot
