Bronchitis is the inflammation of the bronchi. It may develop suddenly,
             following a head cold (acute bronchitis), or it may persist or return
             regularly for many years, causing progressive degeneration of the bronchi
             and lungs (chronic bronchitis). Certain people are more susceptible than
             others; Men are more of a target to bronchitis than women, out numbering
             them 10 to 1 cc the reasons are unclear. Of course smokers are 50 times
             more likely to get chronic bronchitis than noncsmokers. Acute bronchitis
             is a bacteria or virus infection, often following a cold smoking. People
             who have acute bronchitis usually have a mild fever, soreness under breast
             bone, irritated by coughing. First they have a dry cough then the cough

             night than during the day, and when the person breathes in smoke and fumes.
             The main symptoms most recognized in chronic bronchitis is, again, a cough,
             with sputum, often occurring in paroxysms. Other symptoms in chronic
             bronchitis are dependant on how much, or how little, emphysema is present.
             This disorder causes the lungs to become overstretched, making the
             breathing process difficult. The chronic bronchitic with no emphysema tends
             to be overweight and often has a bluish tinge to his or her li...
