A low eosinophil count may be caused by physiological reasons such as hunger and exertion, or by pathologic reasons such as severe burns or major surgery.
Physiologic causes include factors such as hunger, exertion, mental stimulation, or cold, which can cause a physiologic decrease in eosinophils in the blood, resulting in a low eosinophil count.
Pathological causes of eosinophilia include severe burns or major surgeries, early typhoid fever or paratyphoid fever, and prolonged use of adrenocorticotropic hormone, adrenocorticotropic hormone and other medications, which will cause a pathological decrease in eosinophils, resulting in a low eosinophil count.
If the eosinophil count is low, it is necessary to actively consult a doctor to clarify the cause of the disease and then carry out targeted treatment.
