Elevated white blood cell (WBC) counts often accompany prednisone use, but many other conditions can cause this. Infections, from bacterial pneumonia to viral influenza, frequently trigger a rise in WBCs. Your body’s natural response to fight these invaders increases the number of these cells.
Inflammation also plays a significant role. Conditions like rheumatoid arthritis, inflammatory bowel disease (Crohn’s disease or ulcerative colitis), and lupus can all elevate WBC levels due to the body’s ongoing inflammatory response. This is because your immune system is actively combating inflammation.
Certain cancers, such as leukemia and lymphoma, directly impact WBC production. These malignancies often cause a significant increase in WBCs, sometimes with unusual cell types. Regular blood tests are essential for monitoring these conditions.
Stress, whether physical or emotional, can temporarily raise WBC counts. Severe trauma or surgery, for instance, can trigger this response. This temporary increase usually resolves once the stressor subsides.
Specific medications, beyond prednisone, can also affect WBC counts. Some antibiotics and anticonvulsants are known to cause this side effect. Always inform your doctor of all medications you’re taking.
Finally, a variety of less common causes exist, including certain autoimmune diseases and genetic disorders. A thorough medical evaluation is key for accurate diagnosis and treatment.
