Can you have B12 deficiency without pernicious anemia?
The symptoms of vitamin B12 deficiency can develop slowly and worsen over time. Some symptoms may be experienced by people who have a vitamin B12 deficiency without anemia. Some people may experience no symptoms, despite low levels of vitamin B12.
Can you have pernicious anemia with normal B12 levels?
Spuriously normal vitamin B12 levels can occur in pernicious anaemia due to anti-intrinsic factor autoantibody interference in the laboratory assay. Myelodysplastic syndromes and vitamin B12 deficiency share clinical and laboratory similarities, so a correct differential diagnosis is crucial for adequate treatment.
What is the difference between pernicious anemia and anemia?
Anemia is a condition in which the body does not have enough healthy red blood cells. Red blood cells provide oxygen to body tissues. There are many types of anemia. Pernicious anemia is a decrease in red blood cells that occurs when the intestines cannot properly absorb vitamin B12.
What vitamin is lacking in pernicious anemia?
Folic acid is also called folate. It is another B vitamin. Either a lack of vitamin B-12 or a lack of folate causes a type of anemia called megaloblastic anemia (pernicious anemia). With these types of anemia, the red blood cells don’t develop normally.

How does vitamin B12 deficiency cause pernicious anemia?
Vitamin B12 is needed for hemoglobin production. In other words, vitamin B12 aids the body to produce healthy red blood cells. Therefore, pernicious anemia is a type of vitamin B12 deficiency anemia. The major cause of pernicious anemia is the loss of stomach cells that produce intrinsic factor.
What happens if you have vitamin B12 deficiency?
As with iron-deficiency anemia, a lack of vitamin B12 can also cause your body to make fewer healthy red blood cells. This type of anemia, called pernicious anemia or megaloblastic anemia, is characterized by red blood cells that are larger than they should be and oval-shaped, instead of round.
What is the definition of pernicious anemia ( PA )?
What is Pernicious Anemia (PA) This is defined as a type of megaloblastic anemia, which occurs due to lack of vitamin B12 secondary to malabsorption as a result of intrinsic factor deficiency, a compound secreted by the inner mucosal lining of the intestines.
What’s the difference between iron deficiency anemia and B12 deficiency?
Both types of anemia are characterized by a smaller number of healthy red blood cells. Credit: hobo_018/iStock/GettyImages. There are two major nutritional causes of anemia: B12 and iron deficiency. A deficiency in another B vitamin, called folate, can also cause anemia.
