Chronic obstructive pulmonary disease (COPD) is a lung condition that develops because of breathing in polluted air. It is a progressive problem that intensifies over a period of time. Some common COPD symptoms are difficulty breathing, wheezing, chronic cough, fatigue, and shortness of breath. Although the disease is not entirely curable, specific treatments can help manage the signs. These include non-invasive ventilation, medication, physical exercise, and oxygen therapy.
