Symptom Guide For Vitamin B12 Deficiency

Numbness Or Tingling

The numbness or tingling sensations can occur due to nerve damage resulting from a severe vitamin B12 deficiency. The nerves in the body are covered by a protective sheath known as myelin. Vitamin B12 is an important contributor in the metabolic pathway leading to the production of myelin.

If there is not enough vitamin B12 in the body, the protective sheath is produced differently where it fails to protect the nerve ending from damage by free radicals. A burning sensation on various parts of the body is among the signs the nerves have lost their protective sheath. The numbness and tingling are mostly felt in the hands and the feet. With that said, the sensation of pins and needles may have many causes, so other symptoms of a vitamin B12 deficiency must be present for an accurate diagnosis.
