What Causes a Vitamin B12 Deficiency
Vitamin B12 deficiency means exactly that. Your body does not have enough of the B12 vitamin to complete necessary bodily functions. This may be due to an insufficient amount of Vitamin B12 in one's diet. It is rare to not consume enough Vitamin B12 on a daily basis. However, vegetarians and vegans are at a greater risk of vitamin B12 deficiency due to the lack of the consumption of the B12 sources such as meat and dairy products. A Vitamin B12 deficiency may also be due to the body's inability to absorb or properly use Vitamin B12. Certain diseases such as Crohn's, digestive tract surgeries, certain medications and alcohol consumption may affect the bodies ability to absorb Vitamin B12.
Pernicious anemia is another cause of a Vitamin B12 deficiency. This is due to the deficiency of intrinsic factor. Intrinsic factor is produced in the stomach and is used in the small intestine to absorb Vitamin B12.

Vitamin B12 Deficiency Treatment
With early diagnosis, a Vitamin B12 deficiency can be successfully treated with minimal damage to the body. Treatment includes restoring your bodies Vitamin B12 supply. This can be done by;
- Oral B12 vitamins. This will be a higher dose than what would be found in a regular multivitamin.
- Vitamin B12 intramuscular injections. These may be started with one injection a week. And then one injection per month.
- Vitamin B12 nasal spray.
Other treatments of a Vitamin B12 deficiency include;
- Treatment of the underlying cause of the deficiency
- Changing your diet. Including more foods high in Vitamin B12, such as meats and milk products.
Usually treatments are lifelong depending on the cause. Most people have relief from the symptoms soon after treatment has begun. However, in severe cases treatment will not correct any/all brain and/or nerve damage already done. Your doctor will again check your levels of Vitamin B12, through a blood test, a few months after beginning the treatment.
Vitamin B12 in pill form is not always successful in treating a vitamin B12 deficiency and you may need to consider receiving injections. Injection treatments are more successful in treating a vitamin B12 deficiency because an intramuscular injection is better absorbed by the body than the oral route.
