In general, high eosinophils cannot be cured by themselves. Eosinophil refers to eosinophil, and its high index is often caused by parasitic infections, skin diseases, blood diseases, etc. It is necessary to clarify the cause of the disease and actively treat the primary disease in order to be cured. 1. Parasitic infections: people are prone to parasitic infections due to poor hygiene habits, eating unclean fruits and vegetables, etc., which may result in high eosinophils, which can be treated with medication under the guidance of a doctor, such as Mebendazole and Albendazole. 2. Skin diseases: high eosinophils can also be seen in skin diseases. Skin diseases are caused by viral infections, physical and chemical stimuli, often accompanied by itching, tingling and other symptoms, because of the body’s autoimmune response, which leads to high eosinophils. Generally, it can be treated by applying prednisone, dexamethasone and other drugs under the guidance of doctors. 3. Hematological diseases: It can be seen in primary eosinophilia, which cannot be cured by itself, and the treatment drugs include glucocorticosteroids such as prednisone. Eosinophilic granulocytes are generally not self-curable. As one of the components of leukocytes, eosinophils are important cells in the immune response process and are closely related to the disease response, so eosinophil values can be restored by treating the primary disease. Patients should also pay attention to skin protection, light diet, avoid overeating, eating spicy and stimulating food. Drugs need to be used under the supervision of a physician.
