In this post, you will figure out what causes vitamin B12 deficiency, what are symptoms and treatments, and which foods can help you get vitamin B12 naturally.
B12 deficiency can be a consequence of different factors such as malabsorption, nutrient insufficiency, or inherent reasons.
Lack of vitamin B12 can lead to macrocytic anemia and neuropsychiatric disorders.
If our bodies can’t absorb B12 for a long time, a shortage of this essential vitamin will take place.
What causes vitamin B12 deficiency can be three primary reasons as following:
1. Dietary Insufficiency
Your body stores surplus vitamin B12 in the liver. If your body can’t get this vitamin naturally from your diet for the long term, it will start to use the stored B12.
Here is where the deficiency will arise over time.
A study shows that the risk of B12 deficiency and anemia in people who suffer from autoimmune thyroid disease is higher than others.
The absence of inherent factors can result in malabsorption of vitamin B12 in people who endure pernicious anemia.
Also, gastric bypass surgery, damages to the small intestinal, or tapeworm infection can increase the risk of B12 deficiency.
Besides, any conditions related to ileal inadequate functioning, namely, tropical sprue, coeliac disease, and Crohn’s disease may bring about malabsorption and consequently B12 deficiency.
