What happens when wbc count goes down?

When the white blood cell (WBC) count decreases, a condition known as leukopenia occurs, which can impair the body's ability to fight infections. This reduction may result from various factors, including bone marrow disorders, autoimmune diseases, severe infections, or the effects of certain medications and treatments. A low WBC count can increase susceptibility to infections, leading to symptoms like fever, fatigue, and increased illness. Monitoring and addressing the underlying causes are crucial for restoring immune function.
