What causes white blood cells to rise?

There are many potential causes for an elevated white blood cell count. Some common causes include:

- Infection: This is a common cause, as white blood cells help the body fight infection. Infections that cause a high white blood cell count include bacterial, viral, and fungal infections.

- Inflammation: Inflammation refers to the body's response to injury or irritation. Many conditions can cause inflammation, leading to an elevated white blood cell count, such as rheumatoid arthritis, lupus, and Crohn's disease.

- Trauma: Trauma, such as a car accident or major surgery, can cause a temporary increase in white blood cell count.

- Cancer: Some cancers, such as leukemia, cause an abnormal and excessive increase in the production of white blood cells.

- Medical conditions: Certain medical conditions, such as autoimmune disorders, spleen problems, and thyroid disorders, can affect white blood cell production and lead to a high count.

- Medications: Certain medications, such as steroids, chemotherapy, and some antibiotics, can cause changes in white blood cell count.

- Stress: In some cases, stress can cause a transient increase in white blood cell count.

- Exercise: Intense exercise can also lead to a temporary elevation of white blood cell count.

- Allergic reactions: Severe allergies can cause a temporary increase in white blood cell count.

It is important to consult a healthcare professional if you have an elevated white blood cell count. They can order appropriate tests to identify the cause and determine the best course of action for treatment.
