​Vitamin B12 deficiency: Uncommon symptoms that indicate low levels of vitamin B12​

Our body needs 2.4 micrograms of vitamin B12 on a daily basis to perform important functions like the synthesis of nerves, DNA, and red blood cells. Our body can't produce vitamin B12 of its own for performing these functions hence the requirements needs to be met through foods and supplements. When one does not consume enough vitamin B12 through foods, the body reacts to its deficiency in several ways. Here are a few uncommon signs of vitamin B12 deficiency:

One of the classic signs of vitamin B12 deficiency is numbness in the limbs. This happens due to peripheral neuropathy in which the nerves are damaged. Vitamin B12 has a major role in the production of neurotransmitters and lack of its affects nerve transmission.

People who have extremely low levels of vitamin B12 find it difficult to walk in a proper manner. This is another consequence of peripheral nerve damage. Due to numbness in limbs, especially feet, it gets difficult for a person to walk properly.

Lack of vitamin B12 leads to glossitis. This is a condition where the tongue swells up and changes color. It appears more reddish. One also experiences unexplainable itching and burning sensation in the mouth.

Vitamin B12 is directly associated with mental health. It leads to cognitive difficulties and affects the reasoning and thinking ability of an individual which is mostly due to the disruption in neurotransmitters. Memory loss is a classic symptom of vitamin B12 deficiency which many people ignore.

Fatigue is commonly seen in those who have low levels of vitamin B12, though it is underdiagnosed in many.
