Vejthani

Because vitamin B12 deficiency can take a while to develop, it may be years before symptoms show up, gradually intensifying over time. Moreover, these symptoms may be confused with those of other conditions.

Here are signs and symptoms to look out for if you are at risk of having a vitamin B12 deficiency.

1. Tingling and Other Strange Sensations

Your nerves are surrounded by a fatty substance called the myelin sheath. This lipid-rich layer serves as insulation and protection for your nerves. A lack of vitamin B12 may cause damage to your myelin sheath, resulting in nerve damage. This is one of the more severe side effects of long-term vitamin B12 deficiency. This may lead to symptoms such as numbness and tingling in the hands and feet, and paresthesia, which is the sensation of pins and needles.
