What is heavy chronic bronchitis caused from?

Answer 1

Heavy chronic bronchitis is primarily caused by long-term exposure to irritants that damage the airways, with cigarette smoke being the most significant factor. Other contributors include air pollution, dust, chemical fumes, and recurrent respiratory infections. This condition leads to inflammation and excessive mucus production in the bronchial tubes, resulting in persistent cough and breathing difficulties. Managing exposure to these irritants and seeking medical treatment are crucial for alleviating symptoms.
