Emphysema is a type of chronic obstructive pulmonary disease (COPD) that primarily involves the destruction of the alveoli in the lungs, leading to a reduction in respiratory function. One of the hallmark symptoms of emphysema is a chronic productive cough. This cough often results from the accumulation of mucus in the airways as the body attempts to clear debris and irritants. Patients may notice that their cough produces sputum, which can vary in color and consistency.

In the context of learning about the symptoms of emphysema, it's vital to understand that while some patients may experience wheezing or have a dry cough at times, the persistent and productive nature of the cough is a key indicator of the disease. Chronic productive cough occurs in the later stages of the disease as lung function declines and the airways become obstructed. Recognizing this symptom can aid in differentiating emphysema from other respiratory conditions, which may present differently in terms of cough characteristics.
