When you lack in vitamin B12, it could also lead to nerve cell damage leading to pins and needles sensation in hands and feet. If unchecked it could become a permanent condition called paraesthesia. B12 is required for myelin production that protects the nerve fibers and increases the nerve impulses. Lack of vitamin B12 also leads to deterioration of cerebral tissue, optic nerve, spinal cord and peripheral nerves. Further signs could be loss of balance, and wobbliness while walking on flat surfaces.

4. Swollen, inflamed tongue

Among signs of vitamin B12 deficiency, lacking in the vitamin is experienced by 10-15% of people over 60. Either they could have a direct vitamin B 12 deficiency or a health condition that leads to reduction of vitamin B12. Ageing decreases absorption of protein bound vitamin B12. In this case, treatment should be done immediately to prevent irreversible damage that could put one at risk of dementia, confusion and decline in cognitive ability. It is necessary to eat fortified foods to boost the vitamin levels in the body.

Apart from these signs of vitamin B12 deficiency, there are other factors that cause lack of the vitamin. Conditions like weight loss surgery, celiac disease, chronic alcoholism, IBS can obstruct absorption of vitamin B12. Even if one has moderate symptoms, consult a doctor for the necessary supplements of vitamin B12.
