Vitamin B12 deficiency symptoms: Three signs you can see on your skin

Other symptoms of a vitamin B12 deficiency

As well as skin manifestations of a vitamin B12 deficiency, there is the gastrointestinal issue of glossitis.

Glossitis is a sore or white tongue, clarified the national health body.

A vitamin B12 deficiency can also lead to “neuropsychiatric” symptoms, such as irritability, cognitive and olfactory impairment.

The AARF added that it can also lead to areflexia, which is when the muscles don’t respond to stimuli.
