"Why Do Eosinophil Counts Tend to Be Low in Sinusitis?"

Reasons for Low Eosinophil Count in Sinusitis

Low eosinophil levels in sinusitis may stem from various factors such as the early stage of sinusitis, mild sinusitis symptoms, medication effects, and more. Patients are advised to seek medical attention promptly and follow the treatment plan under a doctor's guidance. Here are some possible reasons:

1. Early Stage of Sinusitis

Sinusitis is an inflammatory reaction of the sinus mucosa caused by bacterial infection. If sinusitis is in its early stage, the number of pathogens may be low, which may not trigger an increase in eosinophils, resulting in the aforementioned situation. Typically, no special treatment is required, and as the condition progresses, eosinophil levels will gradually rise.

2. Mild Sinusitis Symptoms

Patients with mild sinusitis symptoms, such as slight runny nose and sneezing without other discomforts, may exhibit low eosinophil counts in test results. In general, no specific treatment is necessary. Patients are advised to rest adequately and avoid unhealthy habits like overexertion and staying up late.

3. Medication Effects

If a patient has taken anti-allergic medications, such as Loratadine Tablets or Cetirizine Hydrochloride Tablets, before a blood routine examination, these drugs may suppress eosinophils, leading to low counts. This is usually normal and eosinophil levels will return to normal after discontinuation of the medication.

4. Other Factors

Patients with immune system disorders or hematological diseases may have weakened immune systems, predisposing them to sinusitis. Such patients' abnormal immune function can also cause low eosinophil levels. They are advised to undergo relevant examinations for diagnosis and follow the doctor's instructions in taking medications like Prednisone Acetate Tablets, a glucocorticoid.

In daily life, patients are encouraged to maintain a light diet, including protein-rich foods like eggs and milk. It's also important to stay hydrated, maintain a positive mindset, and avoid emotional stress.
