What causes B12 deficiency?

People who have a condition called pernicious anemia lack a natural substance needed to absorb B12 from the intestines and can develop a B12 deficiency. Also, people who follow special dietary instructions, for example, a strict vegetarian diet, can develop B12 deficiency. On the other hand, people who eat a standard diet, including meat, fish, and dairy products, usually get enough B12 from food.

What happens if B12 is low?

Low B12 levels can lead to neurological symptoms, nerve damage, and a type of anemia called megaloblastic anemia. Signs and symptoms of low B12 include glossitis (inflammation of the tongue), fatigue, pale skin, palpitations, weight loss, numbness and tingling, infertility, and dementia.
