Leukocytosis in infants: causes, symptoms, treatment
Leukocytosis in children is most often not a disease, it is a pathological condition that is caused by a change in blood composition, namely, an increase in the level of leukocytes. Such a phenomenon in most cases should not cause panic or anxiety, since this is how the body reacts to the action of internal and external factors. However, sometimes an increase in the number of leukocytes can be a sign of the pathological process taking place in the baby’s body. When does leukocytosis present a health risk and require treatment?
Leukocytes are also known as white blood cells, although in reality they are colorless. In the body they perform a protective function, that is, they recognize harmful microbes and bacteria and literally attack them. The reaction of leukocytes is instantaneous, thanks to the blood vessels they easily spread throughout the body. These cells are produced:
- the spleen;
- bone marrow;
- lymph nodes.
In the first day of life of the newborn, the level of leukocytes in his blood is between 8.5 and 24.5 units, this is due to the lack of formation of the immune system in the baby. This indicator persists for several weeks, but gradually it decreases and by semiannual age should be in the range of 5.5-12.5 units. Exceeding these values is called leukocytosis.
