Chronic bronchitis is known to be a chronic inflammatory disease that is attached to the bronchi, which is characterized by mucus formation in the respiratory tract and prolonged cough. Emphysema, on the other hand, is a chronic progressive disease of the lung where there is a destruction of the tissues that are supporting the function of the lungs.
The major thing that causes chronic bronchitis is smoking. Risk factors include a weak immune system, polluted air, continuous attack of acute bronchitis, and irritants. Just in a similar manner, the major cause of emphysema is also smoking. Risk factors include hereditary factors, asthma or allergies, air pollution, age, male gender, and the deficiency of congenital alpha-1 antitrypsin.
The symptoms of chronic bronchitis are swelling and inflammation of the bronchi, lack of air, fatigue, chest pain, rales, and the production of yellow, green, or white sputum. The symptoms of emphysema include severe dyspnea, enlarged chest, and effort to exhale.
