Chronic obstructive pulmonary disease. Chronic obstructive pulmonary disease (COPD) is a common lung disease. Having COPD makes it hard to breathe. There are two main forms of COPD: Chronic bronchitis, which involves a long-term cough with mucus. Emphysema, which involves damage to the lungs over time.
Chronic Cough Is the First Symptom. Cough is the first sign of COPD. According to the Mayo Clinic, COPD is diagnosed if your cough is persistent for three months (or longer) out of a year for at least two years. The cough may persist every day, even if there are no other symptoms of illness, such as a cold or the flu.
