10 COPD Symptoms
Reviewed: Dr. Gromatzky
Symptom #3: Cough
A cough is a sudden and repetitive reflex that helps clear the airways of irritants, foreign particles, and fluids. It comes in the form of a distinctive sound produced by the violent release of air after the opening of the glottis.
Frequent coughing usually means that there may be an underlying disease or infection. Through an evolutionary perspective, pathogens such as viruses and bacteria have “learned” to spread to new hosts by causing the infected host to cough. Coughing is commonly observed with air pollution, asthma, COPD, post nasal drip, lung cancer, heart failure, and more.
