Four alarm alarming vitamin B12 deficiency that cannot be ignored

Vitamin B12 is one of the most important trace elements, which depends on the normal functioning of both the body and the brain. Its deficiency often develops unnoticed, but can subsequently lead to serious disorders in the body. Doctors named four key symptoms that may indicate a lack of this substance.

1. The inflamed tongue

One of the first B12 deficiency signals is changes in the tongue. In the case of deficiency, a condition known as glossitis may occur. The tongue turns red, swells, becomes painful and as if "smooth" - due to the disappearance of taste receptors. Tongue lesions - an early marker of disorders in metabolic processes that accompany B12 deficiency.

2. Tingling in the extremities

This vitamin plays a key role in the production of myelin - a substance that forms a protective sheath around the nerves. Without it, the transmission of impulses in the nervous system is disturbed, which is manifested in the form of tingling, numbness or burning, most often - in the hands and legs.

3. Vision Deterioration

Insufficient B12 can also affect the optical nerve, which leads to visual impairment. A person may feel the fuzzy image or partial loss of visual acuity, especially in chronic deficiency.

4. The constant fatigue and weakness

B12 is involved in the production of erythrocytes, which are responsible for the delivery of oxygen to the tissues. If the vitamin is lacking, the number of red blood cells decreases and the cells do not get enough oxygen. As a result, there is a general weakness, lethargy and a decrease in energy, even without physical activity.

How to fill in B12 deficiency

Most vitamin B12 is found in animal products - meat, fish, eggs, poultry and dairy products. It is almost absent in plant foods, but some products may be enriched with B12 - for example, certain types of bread or vegetable milk. For vegetarians and vegans, doctors recommend using vitamin in the form of additives.

If you notice the symptoms described - you should consult your doctor and take an analysis for B12. Early diagnosis will help to avoid serious complications.
