Chronic Obstructive Pulmonary Disease (COPD) is a lung condition where the lungs are damaged or remodeled in a way that they can't go back to normal, leading to long-term breathing problems.
COPD may be linked to diseases that make it hard to breathe, like emphysema, chronic bronchitis, certain genetic issues, and injuries to the brain or spine. Asthma isn't considered COPD, but some people with asthma might also have COPD.
