Monocytes in the blood increased: the main causes

Monocytes are one of the varieties of white blood cells. And despite the fact that they account for only 1–8% of all white blood cells, it is impossible to overestimate their importance for the body. After all, these structures are involved in the neutralization of bacterial infection and the removal of foreign bodies from the body. But what does it mean if monocytes are elevated in the blood?

Monocytes and their role in protecting the body

As already mentioned, these cells are a type of white blood cell. It should be noted that these are rather large structures, which, like all blood cells, are formed in the bone marrow, after which they enter the bloodstream, where they remain active for about 70 hours. After that, monocytes migrate into the tissues of the organs (a large number of them are found in the liver and spleen). This form of white blood cells is primarily responsible for the elimination of bacterial infections, since the size of the cells allows them to absorb and remove rather large structures, including pathogenic microorganisms and damaged tissues.Monocytes in the blood also provide antiviral and antifungal protection. Their main functions include the formation of a specific immune response of the body. In addition, they can slow down the process of malignant transformation and the formation of tumors. Therefore, it is natural to assume that monocytes in the blood are elevated in the presence of an infectious disease. But this is not all reasons.

If a significant increase in the number of these cells was found during a blood test, the reasons may be as follows:

  • infectious diseases, including such severe ones as tuberculosis, brucellosis, sarcoidosis, and syphilis;
  • viral and fungal infections;
  • systemic autoimmune processes, such as lupus erythematosus, some forms of polyarthritis, rheumatoid arthritis;
  • blood diseases, in particular, lymphogranulomatosis, leukemia;
  • the formation of malignant tumors;
  • infective endocarditis;
  • if monocytes are higher than normal, then this may indicate some diseases of the digestive tract, in particular, the presence of ulcerative colitis;
  • In addition, a change in the leukocyte formula is observed in case of severe poisoning of the body with toxic substances.

It should be said that with similar test results, you should immediately consult a doctor. An increase in the level of these cells in the blood indicates only the presence of an inflammatory process, but does not at all explain the reasons for its occurrence. It is advisable to pay attention to the presence of any symptoms. For example, infectious diseases are often accompanied by fever, and enteritis and ulcerative colitis will affect the work of the digestive system. Be sure to tell your doctor about your well-being. To make an accurate diagnosis, it is necessary to conduct several additional tests and studies - this is the only way to accurately determine the cause of the increase in monocytes. Naturally, treatment depends on the disease that caused the increase of this type of white blood cells.
