    Chronic bronchitis is a disease with cough and expectoration, which lasts for at least 3 months or more than one year, sometimes for more than two years

    Common causes of the disease include: Smoking - smoking causes the trachea to contract, the cilia to move slowly, the airway resistance to increase, the mucous membrane to be thick, the glands, more and more goblet cells and mucus to secrete excessively

    Although smoking is considered the most important cause, only 12 to 15 percent of smokers suffer from chronic bronchitis

    Air pollution: Industrial and household smoke and sulfur dioxide are the main air pollution factors causing chronic bronchitis

    Infection: the role of infection is uncertain, but now it seems that once chronic irritation develops, it may become emphysema

    It mainly involves Haemophilus influenza and Streptococcus pneumoniae

    Mycoplasma pneumonia may also be involved

    Occupation: coal miners and industrial workers exposed to dust and smoke are often stimulated to cause bronchitis

    In addition to the above reasons, family heredity and genetic abnormalities related to alpha antiprotein deficiency are also one of the reasons

    The following are the common types and symptoms of this disease: the main symptom of chronic bronchitis is expectoration, which starts from "winter cough" and "smoker cough", gradually increasing the severity and duration

    The concentration of expectoration varies according to the degree of infection

    In addition, there are shortness of breath, airway obstruction, bronchospasm and other symptoms, long-term development can form emphysema.
