See below: B-12 anemia is a deficiency in vitamin b-12 (cobalamin). Pernicious anemia is a deficiency or lack in intrinsic factor (produced by cells in the stomach) which is a protein essential for absorption of vitamin B12 in the ileum (small intestine). Pernicious anemia requires replacement of intrinsic factor &/or b-12. B-12 anemia needs only b-12 supplementation.

If my baby has anemia, is it safe to give him iron supplements?

Yes: Not only is it safe, but it is essential. Untreated iron-deficiency anemia can lead to permanent problems with school and behavior. Iron is absolutely essential to normal human health. If a baby's iron is low and he cannot get it in his diet, he must take supplements.

Hi im anemic and my doctor want me to do iron infusion and colonoscopy , why?

Need more info: I suspect that your doctor has found that you have iron deficiency anemia. This is a very straightforward diagnosis to make. The colonoscopy is helpful to make sure that you are not losing it in the bowel. If oral iron is not helping then you might need IV iron to rapidly make up for what you can't get from pills.
