What illness causes high white blood cell count?

Leukocytes, commonly referred to as white blood cells, are likely what is meant by "white blood." In general, elevated white blood cell counts may be caused by conditions such as pneumonia, rheumatoid arthritis, leukemia, and others. Specific analyses are as follows:

1. Pneumonia

Pneumonia refers to inflammation of the terminal airways, alveoli, and lung interstitium. Main symptoms include fever, cough, and sputum production. Infections associated with pneumonia can lead to increased white blood cell count. Patients are advised to follow medical instructions and use medications such as cefdinir tablets or cefradine capsules for treatment.

2. Rheumatoid Arthritis

Rheumatoid arthritis is a systemic autoimmune disease that often presents with joint swelling and pain. Blood routine tests may reveal elevated white blood cell counts. Patients are advised to follow medical guidance and take medications such as ibuprofen sustained-release capsules or diclofenac sodium enteric-coated tablets.

3. Leukemia

Leukemia is a malignant clonal disorder originating from hematopoietic stem and progenitor cells. Symptoms may include fever and bone pain. Most patients show elevated white blood cell counts during routine blood examinations. Treatment should follow medical advice using drugs such as imatinib mesylate capsules or nilotinib capsules. When feasible, hematopoietic stem cell transplantation should be performed promptly.

In addition, other diseases such as suppurative tonsillitis, scarlet fever, sepsis, systemic lupus erythematosus, and lymphoma may also cause similar findings. Patients experiencing discomfort should seek timely medical attention to avoid delays in treatment. Additionally, maintaining a light diet and ensuring adequate rest are recommended in daily life.
