Eosinophilic bronchitis, or eosinophilic bronchitis, is often characterized by a dry cough, little sputum and wheezing. Eosinophilic bronchitis is related to the inhalation of allergens such as dust and chemicals, and is characterized by a large number of eosinophilic infiltration in the airways, with symptoms similar to those of bronchitis, which makes it easy to misdiagnose. The disease is characterized by a chronic irritating dry cough or a small amount of mucous sputum, with wheezing in the morning, which lasts for more than 8 weeks without any other significant symptoms. Routines are mostly normal, with a few mildly elevated eosinophil counts. Chest X-ray was normal. Pulmonary function tests are all unremarkable and there is no airway hyperresponsiveness. Eosinophilic bronchitis should go to the hospital in time, under the guidance of the doctor’s active treatment, so as not to delay the condition.
