Right middle lobe bronchial stenosis manifests itself in various ways, such as coughing, coughing up sputum, blood in sputum or hemoptysis as well as dyspnea and wheezing.
1. Cough, cough sputum: It is the most important symptom of bronchial stenosis. Bronchial stenosis due to infections, malignant tumors and other reasons will lead to a decrease in the ability of the airways to clear secretions and produce excessive airway secretions, which will lead to coughing and coughing up sputum.
2. Blood in sputum or hemoptysis: especially in central lung cancer, bronchial stenosis caused by tumor, necrosis of tumor tissue or rupture of bronchial arteries may appear with blood in sputum or hemoptysis.
3. Dyspnea and wheezing: it is mostly seen in asthmatic stenosis caused by bronchial asthma, which manifests as expiratory dyspnea and high rumbling sound in lungs.
It is recommended that patients go to the hospital in time to improve the relevant examination and receive standardized treatment.
