The causes of high or low levels of eosinophils vary from case to case and depend on existing medical conditions. Sometimes the body redirects a large number of eosinophils to a specific site. This is eosinophilia and is usually due to an infection.
Some health conditions such as autoimmune diseases, tumors, endocrine disorders, and skin conditions can prompt eosinophilia, as well. Specific diseases that can lead to eosinophilia include parasitic infections, asthma, Crohn's disease, and cancer. Allergic reactions and parasitic infections are the most common causes of high levels of eosinophils.
