Causes of B12 Deficiency 

Vitamin B12 deficiency occurs when the body does not have enough vitamin B12 to function properly. Deficiency can be caused by a number of factors, including:

Dietary Deficiencies

One of the biggest reasons of B12 deficiency is lack of B12 in your diet. Individuals following a vegetarian or vegan diet may not get enough vitamin B12 from their diet and may need to take supplements or eat fortified foods.

Malabsorption

Lack of intrinsic factors is another reason of occurring B1 deficiency. In addition, intrinsic is a  protein produced by the stomach lining that is necessary to absorb vitamin B12. Intrinsic factor binds to vitamin B12 in the stomach, allowing it to be absorbed by the small intestine. If the body does not produce enough intrinsic factors, vitamin B12 cannot be absorbed, leading to a deficiency. This condition is known as pernicious anemia.

Medical Conditions

People who take these medications may need to use B12 supplements in order to prevent deficiency.

Alcohol Abuse

Consumption of alcohol may also lead to B12 deficiency. Long-term alcohol consumption can damage the lining of the stomach and small intestine, reducing the absorption of vitamin B12.
