This document discusses neutrophilia, which is an increased number of neutrophils in the blood. Neutrophils are a type of white blood cell that helps fight infections. Neutrophilia can be caused by infections, inflammation, smoking, stress, and other factors. Symptoms may include bleeding, low body temperature, and respiratory issues. The absolute neutrophil count is used to define neutrophilia as greater than 8,000 cells per cubic mm. Treatment involves identifying the underlying cause, bone marrow testing, medication changes, and lifestyle modifications to support the immune system.
