Two small changes in the mouth can reveal a vitamin deficiency that affects blood, nerves and energy

We all know that vitamins and nutrients are essential for the proper functioning of the body, and we usually get them through food. However, sometimes a deficiency of certain nutrients can occur, and two unusual symptoms in the mouth can indicate a deficiency of the important vitamin B12.

Vitamin B12 plays a key role in the body, maintaining the health of blood cells and nerves and helping to prevent anemia, a condition that can cause chronic fatigue and weakness. Although fatigue, numbness and weight loss are common signs of vitamin B12 deficiency, there are other less well-known symptoms, writes Express.co.uk.

According to the guidelines of the British National Health Service (NHS), a painful and red tongue, known medically as glossitis, can signal a lack of vitamin B12. Glossitis causes a change in the color and shape of the tongue, which becomes painful, red and swollen. Due to inflammation, the tongue can also take on an unusual smooth appearance, as the small bumps on the surface, which contain the taste buds, disappear. Another possible symptom is ulcers – small, painful sores in the mouth.

Insufficient vitamin B12 can lead to anemia, and one of its signs is the loss of the sense of taste. Deficiency usually results from irregular feeding. A diet rich in meat, fish and dairy products usually provides sufficient amounts of this vitamin. Therefore, people who do not regularly consume these foods are more at risk of developing a deficiency.

Anemia caused by a lack of vitamin B12 is usually treated with injections. If you suspect that you may be deficient, it is advisable to consult your family doctor, who can instruct you to do a blood test to check the level of the vitamin in the body.
