The diagnosis is made by physician, following the typical course of the disease and auscultation of the lungs. Cough and dyspnoea are the regular symptoms of the disease. Cough with expectoration of secretion occurs mostly in morning hours. Sometimes, wheezes and dry rales may also be heard in the lungs.

Chronic bronchitis requires complex therapy.
