Please what's the difference between pernicious anemia and vitamin B12 deficiency. My iron levels are perfect. I'm getting injections for vitamin b12.

Intrinsic factor: Vitamin B12 is present in meat and animal protein foods. Absorption of B12 occurs in the intestine (ileum) and requires intrinsic factor (IF), made by stomach cells. In pernicious anemia, IF production is deficient, and results in anemia, a reduction in hemoglobin/hematocrit. One can be vitamin B12 deficient without becoming anemic and/or without having deficient IF. Best wishes:) ...Read more

However, if levels are already low, i'd recommend starting B12 injections and testing for pernicious anemia. ...Read more
