The first two signs of B12 deficiency are named

Low levels of vitamin B12 and iron are the main causes of anemia. This condition occurs when the body does not have enough healthy red blood cells, which are responsible for delivering oxygen to the tissues.

The first symptoms of anemia are usually loss of appetite, constipation, headaches, irritability, and difficulty concentration of attention. However, there is another important symptom of B12 deficiency that is often overlooked.

The vitamin is critical to the proper functioning of the body and performs many vital functions, including making DNA and red blood cells. It is necessary for the health of nervous tissue and brain activity. Therefore, quite often the first sign of its deficiency is pain in the face, which, as a rule, appears only on one side.

“This pain is so different from person to person that it is difficult to describe it. It can be a dull pain in the cheekbone right under the eye, a sharp shooting pain in the forehead, sometimes going from the forehead to the nose,” the doctors said. The sensations can be quite sharp, but fleeting.

Another sign is a pale complexion, sometimes with a yellow tint. The main cause of this symptom is insufficient production of red blood cells.

To prevent vitamin B12 deficiency, it is recommended to include or increase the amount of animal products in the diet, especially meat and dairy products. If the body is unable to absorb the substance naturally, doctors prescribe B12 injections.
