COURSE (development) OF COPD
Most people with COPD don’t realize that they have a problem until they are 40 years or older.
- At first the patient suddenly starts noticing a mild shortness of breath and occasional coughing.
- Soon he may develop a morning cough that produces a clear, colorless sputum (mucus).
- With further progress of disease, the cough becomes more frequent and the person has to make an increased effort to breathe air in and out of the lungs.
- If left untreated the disease may lead to serious complications like involvement of the heart. When the function of lung and heart is no longer adequate to deliver oxygen to the body’s organs and the tissues, the patient dies.
