Pathological causes of high eosinophil percentage usually include allergic diseases, parasitic infections, malignant tumors and so on.
1. Allergic diseases: for example, drug allergy, food allergy, urticaria, etc., which may cause allergic rashes all over the body, thus causing high percentage of eosinophils.
2. Parasitic infections: For example, intestinal helminth infections, such as roundworms, hookworms, and liver flukes, will increase eosinophil elevation in most cases. In addition, allergic reactions caused by the acute phase of schistosomiasis can also manifest as eosinophilia.
3. Malignant tumors: for example, lung cancer, some lymphomas, multiple myeloma, etc. This is due to the fact that malignant tumors can kill bacteria, which can easily lead to high eosinophil percentage.
4. Blood system diseases: such as chronic granulocytic leukemia and eosinophilic granulocytic leukemia can also lead to high eosinophil percentage.
It is recommended that patients with high eosinophil percentage should go to the hospital in time, and under the guidance of the doctor to clarify the cause of the disease and take effective treatment.
