The following signs indicate someone is deficient in vitamin B12 intake

TEMPO.CO, JakartaVitamin B12 helps the body keep nerve cells and blood cells healthy. This vitamin also plays a role in forming DNA.

The body does not produce vitamin B12 so it can only be obtained through food and drink intake. Deficiency of vitamin B12 can cause several health problems ranging from skin problems, poor eye health, and nervous disorders.

There are a number of common signs seen in people who have a deficiency of vitamin B12. The following is a complete explanation as quoted from Times of India.


National Health Service (NHS) states that if the symptoms of vitamin B12 deficiency can be seen in four parts of the body, namely the hands, arms, legs, or the ankle area and below. People with a deficiency of this vitamin can experience some strange sensations in these four areas of the body. This condition is called paresthesia.

However, experiencing paresthesia is not necessarily an effect of a lack of vitamin B12. It can be caused by a number of other conditions such as pressure on a nerve, pinched nerve, neurological disease, reduced blood supply, hyperventilation, diabetes, multiple sclerosis, hyperthyroidism and many more. Therefore, it is important to carry out tests to confirm the diagnosis.


Apart from paresthesia, glossitis is also a sign of vitamin B12 deficiency. According to WebMDglossitis is characterized by fading or even disappearance of the small bumps on the tongue (papillae).

This can happen because a lack of vitamin B12 can make red blood cells produced in abnormally large quantities and not function properly. It is important to know that glossitis can also occur due to other medical conditions such as allergic reactions, dry mouth due to Sjögren’s syndrome, bacterial, fungal or viral infections, certain sexually transmitted diseases, skin conditions that affect the mouth and others.
