Vitamin B12 deficiency is usually progressive, meaning that it may take years to develop. And when it does the symptoms may manifest differently for different people, depending upon age, gender and genetic vulnerabilities of its victims. The severity of the Signs & Symptoms of Vitamin B12 Deficiency will also depend upon the duration and severity of the deficiency itself.
