👉 Neutrophilia is a condition characterized by an increase in the number of neutrophils, also known as white blood cells. These are immune cells that play a crucial role in the defense and healing processes of the body. They are found mainly in the bloodstream, but they can also be found in other tissues like the lining of the stomach or intestines. Neutrophilia is usually not serious but can sometimes lead to infections if it becomes chronic and persists for an extended period.
