Vitamin B12 is one of the most important vitamins which human being needs in their nutrition in day to day life. Cobalamin is the common name of vitamin B12, It is soluble in water and plays a major role in the metabolism of human cells as well as in the metabolism of fatty acids and amino acids.
Also, it plays a huge and significant role in the process of DNA synthesis. The half-life of vitamin B12 is about 6 days and metabolism occurs in the liver where its half-life is about 400 days. In it is excreted by the kidney.
It is absorbed from our digestive tract at the distal part of the small intestine called the ileum with the help of an intrinsic factor present in the colon.

- Poor diet
- Mal absoption
- Defect in stomach mucosa
- Any kind of defect or condition which cause damage or affect the intestines
- Some Medications
Deficiency Of Vitamin B12 Due To Intrinsic Factor.
There is one protein named intrinsic factor which plays a major role in the absorption of vitamin B12. This intrinsic factor is produced by the stomach and get stored in the ilium.
Due to any kind of defect in stomach mucosa or damage to the stomach, mucosa causes damage to parietal cells also. These parietal cells are responsible to produce the intrinsic factor, therefor damage leads to no production or less production of this protein leads to deficiency of vitamin B12.
Anemia due to deficiency of intrinsic factors is also known as pernicious anemia. Which may show neurological symptoms also.
Sometimes it is autoimmune in which the immune system of the body harms the healthy tissue of the body, which may lead to the deficiency of vitamin B12.

Damage to stomach mucosa.
Any kind of damage to stomach mucosa due to conditions like a gastric ulcer or decrease in the area of stomach mucosa due to partial gastrectomy can lead to less production of intrinsic factors which ultimately leads to low absorption of vitamin B12. This causes a deficiency of B12.
Any Condition Which Affects the Intestine.
Condition like peptic ulcer or damage to the mucosa of the intestine can lead to malabsorption and results in vitamin B12 deficiency.
Pregnancy & Some Medication.
Mothers during pregnancy are more prominent to deficiency of vitamin B12. During pregnancy nutrition need for B12 is increased compared to a normal day because the growing baby inside the mother needs more amount of B12.
And if this requirement is not fulfilled during the period of pregnancy then the mother has an increased chance to develop B12 deficiency.
