BronchitisBronchitis is an obstructive pulmonary disorder characterized by inflammation of the bronchi of the lungs. Airways are the tubes in your lungs that air passes through. The inflammation may be caused by a virus, bacteria, smoking or the inhalation of chemical pollutants or dust. The mucus plugs up the airways and makes it hard for you to get air into your lungs. Acute bronchitis is usually a short illness that commonly develops from a severe cold or following other viral infections and is characterised by cough with green sputum and a soreness in the centre of the chest and perhaps fever and some (usually mild) shortness of breath. People with chronic bronchitis also have varying degrees of breathing difficulties. Sometimes chronic bronchitis is called ‘chronic obstructive lung disease' or ‘chronic obstructive airways disease. Most cases of acute bronchitis disappear within a few days without lasting effects, although coughs may linger three weeks or more. But if you have repeated bouts of bronchitis, see your doctor. You may have a more serious health problem such as asthma, chronic bronchitis or emphysema that needs attention. Symptoms of chronic bronchitis include a cough that produces mucus (sometimes called sputum), trouble breathing and a feeling of tightness in your chest. Acute bronchitis is most often caused by one of a number of viruses that can infect the respiratory tract and attack the bronchial tubes. Even one puff on a cigarette is enough to cause temporary paralysis of the tiny hair like structures in your lungs, called cilia , that are responsible for brushing out debris, irritants, and excess mucus. Chronic bronchitis is defined by the presence of a mucus-producing cough most days of the month, three months of a year for two successive years without other underlying disease to explain the cough. People who have chronic bronchitis are more susceptible to bacterial infections of the airway and lungs, like pneumonia. Pneumonia is more common among smokers and people who are exposed to secondhand smoke. Causes of BronchitisThe common Causes of Bronchitis :
