Vitamin B12 performs a number of basic functions in the body, which are responsible for physical and mental processes. Therefore, its deficiency can affect the body in different ways. Doctors recommend paying attention to four main symptoms.

First of all, any malfunctions in the body's systems are reflected on the tongue. For example, glossitis appears with B12 deficiency. In this case, the tongue becomes inflamed, changes shape and color, becomes swollen, red and painful. In addition, the receptors practically “disappear” on it, which makes the tongue appear smooth.

One of the most serious side effects of B12 deficiency is nerve damage. The substance takes part in the metabolic process, as a result of which myelin is formed. The latter surrounds the nerves with a kind of insulation, without which the nervous system cannot function normally. In toza, a person feels constant tingling all over the body, but most often the limbs suffer from it.

Another symptom of vitamin deficiency is blurred or impaired vision. This is due to damage to the optic nerve system.

In addition, it is worth paying attention to weakness or fatigue. The condition occurs when the body does not have enough B12 to make red blood cells, which carry oxygen around the body. As a result, the bloodstream is unable to effectively transport the vital gas to the cells, so a person begins to experience a sharp lack of energy.

Vitamin B12 is found in animal products, including meat, fish, poultry, eggs and dairy products. It can also be found in some types of bread and vegetable milk.
