					One cause of anaemia is a lack of vitamin B12. Possible reasons for
the vitamin B12 deficiency are malnutrition and a disturbed
absorption in the intestine.




Anemia due to vitamin B12
deficiency - causes


Vitamin B-12 deficiency is a possible cause of anaemia. The reason
for the vitamin deficiency is a disturbed shot of the vitamin in the
intestine or inadequate intake of the food.

Impaired intake
A lack of the so-called intrinsic factor is often the cause   of this
form of anaemia.This is a substance that is produced in the   stomach
and is responsible for the absorption of vitamin B12 in the   small
intestine. A such conditional vitamin B12 deficiency occurs   following
diseases:

     Within a chronic Magenentzündung (autoimmune gastritis),
      produced antibodies are directed against those cells in the
      stomach, which produce the intrinsic factor.The cells are
      destroyed, which developed over time a deficiency of vitamin
      B12.The result is a vitamin B12 deficiency anemia.
     Small intestine diseases (e.g. Crohn's disease), diseases
      caused by the Diphyllobothrium bacterial intestinal bug
      settlement or the surgical removal of large sections of small
      intestine may have resulted that the consumption of vitamin B12
      is disturbed.
     People due to illness of stomach surgery needs to be removed
      which can develop as a result a vitamin B12 deficiency.

Lack of feed
Rarely, a poor diet for anaemia is responsible.Fish, meat and milk
are rich in vitamin B12.Therefore, a food-related lack of vitamin B12
concerns living mostly vegan people who eat no animal food.Even with
old people eat very one-sided sometime there is the risk of vitamin
B12 deficiencies.
