Etiology of recurrent tracheobronchitis: most of them are repeated upper respiratory tract infections, which make the disease spread downward. Most of them are caused by pathogenic microorganisms, and a few are related to primary immunodeficiency and airway malformation. Some children suffer from chronic sinusitis-bronchitis syndrome.
Therefore, I suggest you go to the Pediatrics Department of the Third Affiliated Hospital of Zhengzhou University to find Director Luan Bin for further examination and treatment.
(Dr. Wang Yating solemnly reminds me that because I can't see the patient face to face, I can't fully understand the condition. The above suggestions are for reference only. Please go to the hospital for specific diagnosis and treatment under the guidance of a doctor! )
