Vitamin B12 is crucial for neurological function, the formation of red blood cells, and the maintenance of a healthy nervous system. Deficiency can occur due to inadequate dietary intake (common in vegetarians and vegans), malabsorption issues, certain medical conditions, or medications that interfere with B12 absorption.

If you suspect a vitamin B12 deficiency based on these symptoms or risk factors, it’s essential to consult a healthcare professional for evaluation, diagnosis, and appropriate management. Treatment typically involves B12 supplementation, dietary changes, and addressing any underlying causes contributing to the deficiency.
