There are two main forms of COPD: Chronic bronchitis, which causes long-term swelling and a large amount of mucus in the main airways in the lungs Emphysema, a lung disease that destroys the air sacs in the lungs Most people with COPD have symptoms of both. Alternative Names COPD; Chronic obstructive airways disease; Chronic obstructive lung disease; Chronic bronchitis; Emphysema; Bronchitis - chronic Causes, incidence, and risk factors Smoking is the leading cause of COPD. The more a person smokes, the more likely that person will develop severe bronchitis. Secondhand smoke may also cause chronic bronchitis. Air pollution, infection, and allergies make chronic bronchitis worse. In rare cases, nonsmokers who lack a protein called alpha-1 antitrypsin can develop emphysema. Other risk factors for COPD are: Exposure to certain gases or fumes in the workplace Exposure to heavy amounts of secondhand smoke and pollution Frequent use of cooking gas without proper ventilation Symptoms Cough that produces mucus - may be streaked with blood Fatigue Frequent respiratory infections Headaches Shortness of breath (dyspnea) that gets worse with mild activity Swelling of the ankles, feet, or legs, which affects both sides Wheezing Some people may have few or no symptoms. Signs and tests The health care provider make hear wheezing or abnormal breathing sounds when listening to the chest and lungs with a stethoscope. However, lung sounds can be normal during the exam. In severe cases, a person with COPD can seem anxious and may breathe through pursed lips (the shape lips make when you whistle). During a flare up, the muscles between the ribs contract while the person is breathing in. This is called intercostal retractions. The person will use other muscles to breathe. The number of breaths per minute (respiratory rate) may be high. Continue reading this article
