18 Hidden Causes of High Neutrophil Counts That Doctors Want You to Know

10. Injury

Injuries, especially those that cause significant tissue damage and bruising, increase the risk of individuals experiencing neutrophilia. One of the major reasons this happens is that the body will respond to the injury with inflammation. Inflammation signs, of course, include pain, redness, warmth, and swelling. Neutrophils are part of the immune response to an injury. In fact, neutrophils are the first white blood cells to respond to an injury. They are the cells that release chemical signals to attract other immune cells to the injury. The intent is to heal and protect the injury. However, serious injuries can result in extended periods of inflammation, and thus, neutrophilia.
