What is vitamin B12 deficiency?

A vitamin deficiency is what occurs anytime your body doesn’t have enough of a nutrient that it needs in order to fulfill your basic needs.  Vitamin B12 deficiency is one such type of malnourishment that is sometimes caused by diet, but can also result from other factors, such as autoimmune disorder, medications, illness, or surgical procedures. Of all forms of malnourishment, vitamin B12 deficiency symptoms are the most common in the US.

What causes vitamin B12 deficiency?

Vitamin B12 occurs naturally in all animal-based foods. If you regularly include plenty of meat, poultry, fish, eggs, and milk in your diet, then you probably won’t develop symptoms of vitamin B12 deficiency, as your body is able to store several years’ worth of vitamin B12 in the liver at one time.  If you are a vegan, then you must supplement with vitamin B12 regularly, in order to prevent vitamin B12 deficiency symptoms.

Even if you are a meat-eater, you may still be at risk for suffering a slow depletion of vitamin B12. People with a family history for pernicious anemia, a condition sometimes caused by autoimmune disorders, should check their vitamin B12 levels regularly, in addition to looking out for symptoms indicating vitamin B12 deficiency.

Also, if you regularly suffer gastrointestinal problems, such as diarrhea, vomiting, acid reflux, or stomach ulcers, then you may need to replenish your vitamin B12 levels. Illnesses such as Crohn’s disease, migraines, celiac disease, fibromyalgia, and chronic fatigue syndrome are all high risk factors for vitamin B12 deficiency symptoms.

Patients of gastric bypass surgery or ileostomy should also be on the alert for warning symptoms of vitamin B12 deficiency, as removal of the ileum interferes with vitamin B12 absorption.
