Leukopenia results from conditions and diseases such as aplastic anemia, HIV/AIDS, Kostmann's syndrome, leukemia and myelodysplastic syndromes, which destroy or damage the white blood cells or the bone marrow, according to Mayo Clinic. Congenital disorders, malnutrition, parasitic diseases, insufficient body vitamin, and treatment methods such as chemotherapy and radiotherapy are other possible causes of leukopenia. Additionally, medications including antibiotics and diuretics, and hypersplenism, which is a condition in which the spleen destroys premature white blood cells may also cause leukopenia.
Leukopenia is a condition in which the level of blood leukocytes, which are the cells that protect the body against disease attack, is lower than normal, notes Mayo Clinic. The condition is also known as low white blood cell count. Although different medical practices may have different thresholds for leukopenia, in most cases, patients are said to have leukopenia when their leukocytes are less than 4,000 in 1 microliter of blood. However, this threshold may be different for various sexes and ages.
Doctors discover leukopenia during a blood test, states Mayo Clinic. Patients diagnosed with leukopenia have high chances of developing infections and other diseases because of their weak immune system. To reduce the risks of developing diseases, its is advisable for the patients to practice preventive measures including regular washing of hands, wearing face masks and avoiding contact with people with contagious diseases.
