There are many reasons for elevated white blood cells, depending on the degree of elevation, what type of elevated white blood cells, clinical presentation, etc. Different conditions cause elevated white blood cells, and treatment such as lowering white blood cells varies.
Among these are physiological factors such as strenuous exercise, prolonged exposure to cold air, after a full meal or shower, menstruation, ovulation, and emotional stress, where the increase in white blood cell count is temporary and not high enough to require medication, and normalization quickly occurs after removing the influencing factors. There are many pathological factors, and the methods to reduce the white blood cells vary. For example: various infections: such as certain bacterial, viral, fungal, rickettsial and other infections, treatment is based on anti-infective drugs. Non-infectious inflammatory diseases such as rheumatic diseases are treated mainly with primary diseases. Hematological diseases: acute leukemia (acute myeloid leukemia, acute lymphocytic leukemia, etc.), chronic myeloproliferative diseases (such as chronic granulocytic leukemia, chronic lymphocytic leukemia, true erythrocytosis, idiopathic myeloid metaplasia, primary thrombocytosis, etc.), treatment of the primary disease is the main focus, such as: chemotherapy, etc. Such as chronic granulocytic leukemia, etc., with significantly elevated white blood cells, oral hydroxyurea, application of interferon, etc., but these drugs have significant side effects and are not used casually, and need to be given after medical consultation. Others such as tissue necrosis, acute blood loss and hemolysis, malignant tumors, thyroid crisis or diabetic acidosis can cause neutrophilia, and drugs to treat the primary disease are the mainstay. In addition, some drugs such as epinephrine, catecholamines, glucocorticoids, etc. can also cause leukocytosis, which can gradually decrease after discontinuation. In conclusion, treatment varies with different etiologies and requires a hospital visit to improve the examination and confirm the diagnosis before using the medication.
