Leucocytosis in the blood: a sign of illness?


Is the leukocytosis in the blood a cause for concern or a sign of an active lifestyle? You can never be sure until the end. In any case, this is another reason to check your health.

Leukocytes, or white blood cells, are basicdefenders of the body from external and internal pathogenic substances, agents, organisms. And they realize in the body standard pathophysiological processes (inflammation, allergy, etc.). The level of leukocytes in the blood is judged on the state of the body as a whole.

blood leukocytosis

Excess of the norm of their maintenance in peripheral blood (it is revealed by the usual analysis "from a finger") carries the name "leucocytosis". Usually for an adult, a normal level is 9-11x109/ l. Anything higher is the leukocytosis in the blood.

A living organism is a dynamic system, allthe parameters of which are constantly changing. Similarly, there are daily fluctuations in the level of leukocytes. The so-called physiological leukocytosis in the blood should not cause anxiety. It is enough to overheat (in a sauna, on the beach, on a sunny street or in a hot shop) or intensively exercise - and there will be increased leukocytosis in the blood. Smoking, copious intake of food or emotional stress will also cause an increase in the number of white cells. For pregnant women (especially in the second-third trimesters), leukocytosis is the norm.

leukocytosis in the blood of the cause
To eliminate all of the above factorsthe general analysis of a blood surrender in special conditions (in the morning, on an empty stomach, etc.). But if there is a permanent leukocytosis in the blood, the reasons can be much more serious. In principle, for almost any disease the body responds with increased production of its defenders - leukocytes. Especially it is typical for any inflammation, for example, for bronchitis, pneumonia (generally infectious diseases of the respiratory tract), otitis, bacterial infections of the gastrointestinal tract (including appendicitis, cholecystitis) and the genitourinary system (glomerulo- or pyelonephritis). Especially high figures are reached by leukocytosis in the blood in purulent infections of any localization.

The level of natural defenders of the bodyincreases after hemorrhage, trauma or burn, as well as after surgery or blood transfusion. Leukocytosis is a companion of viral infections (including most often infectious mononucleosis caused by the Epstein-Barr virus), rheumatic diseases (arthritis).

In certain diseases, the number of individual types of leukocytes selectively increases. For example, when the body is infected with any parasite, the number of eosinophils increases.

increased leukocytosis in the blood
Leukocytosis in the blood can indicateoncological diseases, as well as to accompany such acute life-threatening conditions as myocardial infarction. But the most dangerous situation is the blood reaction to the extremely malignant disease of the hematopoietic system - leukemia.

It is important to remember that in itself, leukocytosis is notis a disease. It is only one of the signs that should be evaluated in a comprehensive manner. If the leukocytosis in the blood is detected by accident, then, of course, a doctor's consultation is required to find out its cause.
