A high white blood cell count (WBC), also known as leukocytosis, is not necessarily good or bad. It usually signifies that your immune system is working hard to fight off an infection or inflammation. However, it can also be a sign of more serious conditions like certain blood cancers or bone marrow disorders.
Here's why a high WBC count can be a normal response:
- Fighting infection: When your body is battling bacteria, viruses, or other pathogens, your white blood cells increase in number to help destroy the invaders.
- Inflammation: Inflammation, whether caused by injury or illness, can also trigger an increase in white blood cell count.
However, a persistently high WBC count could indicate:
- Blood cancers: Some types of leukemia and other blood cancers can lead to an abnormally high white blood cell count.
- Bone marrow disorders: Certain conditions affecting bone marrow, such as myeloproliferative disorders, can result in an overproduction of white blood cells.
It's important to consult a healthcare professional to understand the reason behind a high WBC count and receive appropriate treatment if necessary.
