Even if it happens only occasionally, the feeling of breathlessness can be uncomfortable and scary.ĬOPD is an umbrella term for a group of lung diseases, including chronic bronchitis and emphysema, that make it increasingly difficult to breathe because of blocked airways. It’s also associated with bronchospasms, which the Cleveland Clinic says occur when the muscles that line the airways in the lungs tighten, causing wheezing, coughing, and other symptoms.
Difficulty breathing is one of the most troubling symptoms of chronic obstructive pulmonary disease (COPD).
