Various types of infections are common causes of high white blood cells, such as upper respiratory tract infections, various types of pneumonia, lung abscesses, suppurative meningitis, suppurative appendicitis, skin infections, and urinary tract infections, etc. Inflammatory stimuli can lead to increased white blood cells in the body, with fever as the main manifestation, and the clinical manifestations of infections at different sites are different.
With elevated white blood cells, the cause and diagnosis should be clarified first, and anti-infective, symptomatic and supportive treatment should be given.
If high white blood cells are caused by a malignant hematologic disease, such as leukemia, the white blood cell abnormalities in this case are often accompanied by abnormalities in red blood cells, platelets, and hemoglobin. Patients may have malaise, fever, bone pain, swollen lymph nodes, and other uncomfortable manifestations, which are ineffective with symptomatic and anti-infective treatment and require further clear diagnosis by bone marrow aspiration biopsy. Fever in patients with leukemia often recovers gradually with chemotherapy and symptoms improve.
Therefore, it is important to pay attention when high white blood cells are found and seek medical attention in a timely manner. If caused by infection, it can be cured with anti-infection and symptomatic treatment; if it is a hematologic disease, it should be hospitalized as soon as possible to avoid missing the best time to treat the condition.
