Chronic bronchitis

Chronic bronchitis is a disease of the bronchi, manifested by coughing with sputum for at least 3 months for 2 consecutive years with the exception of other bronchopulmonary and / or cardiovascular diseases, which are accompanied by a chronic productive cough.

  • air pollution of residential premises heated by wood-burning stoves;
  • passive smoking;
  • ambient air pollution;
  • frequent respiratory infections in childhood.

The main symptom is a cough with mucosal sputum production. At the beginning of the disease, the cough bothers several times during the day, usually intensifies in cold and wet weather, lasts for several months, but not less than 3, for 2 or more years and gradually becomes permanent;

Chronic bronchitis is a diagnosis of exclusion, because it can be established only in the absence of other pathologies of the bronchi and lungs (bronchiectasis, tuberculosis, pneumonia, bronchial asthma, lung cancer, etc.).
