What causes chronic bronchitis?

Chronic bronchitis is mostly caused by colds and coughs, and it may also be caused by long-term smoking, so we must quit smoking and drinking, and develop a good lifestyle habit.

The nature of the disease is not fully understood, but may be the result of a long-term interaction of multiple factors.

1.Smoking Smoking is the most important environmental element, and according to surveys, the incidence of chronic bronchitis in smokers is 2 to 8 times higher than that of non-smokers.

2.Infectious factors Infection is an important factor in the development and development of chronic bronchitis, mainly viral and bacterial infections.

3.Occupational dust and chemical exposures such as smoke, allergens, industrial exhaust fumes and indoor air pollution, etc., may contribute to the onset of chronic bronchitis in high concentrations or for too long.

4.Air pollution Harmful gases such as sulfur dioxide, nitrogen dioxide, chlorine, ozone, etc. in air pollution can damage the airway mucosal epithelium, reduce ciliary clearance function, increase mucus secretion, and increase conditions for bacterial infection.

The causes of chronic bronchitis are not fully understood, but common factors include the following.

Infect. Infections such as viruses, mycoplasma, and bacteria are one of the important causes of the occurrence and development of chronic bronchitis. Viral infections are influenza virus, rhinovirus, adenovirus, and respiratory syncytial virus.

Bacterial infections are often secondary to viral infections, and the common pathogens are Streptococcus pneumoniae, Haemophilus influenzae, Moraxella catarrhalis, and staphylococcus. These infectious agents cause damage and chronic inflammation of the tracheobronchial mucosa.

Other factors. Physical factors such as impaired immune function, airway hyperresponsiveness, and age are all related to the occurrence and development of chronic bronchitis.

Predisposing factors. Smoking.

Smoking is the main cause of chronic bronchitis. The prevalence of chronic bronchitis in smokers is 2 to 8 times higher than in non-smokers. Chemicals such as tar, nicotine and hydrocyanic acid in tobacco can cause damage to the mucous membranes of the airways.

Occupational dusts and chemicals.

Exposure to occupational dust and chemicals, such as smoke, allergens, industrial exhaust and indoor air pollution, or biofuels, can contribute to the onset of chronic bronchitis at high concentrations or for long periods of time.

Atmospheric pollution. Harmful gases in the atmosphere, such as sulfur dioxide, nitrogen dioxide, chlorine, etc., can damage the epithelial cells of the airway mucosa, and these injuries increase the susceptibility of the airways to bacteria, etc.

Hello, welcome to consult. Chronic bronchitis refers to coughing up sputum for 2 months a year for three or more consecutive years. or cough and sputum for 3 months per year, for two years or more.

This condition can be diagnosed as chronic bronchitis. Common causes of chronic bronchitis are: acute respiratory infections that are not completely controlled, long-term smoking, and low immunity.

At present, these symptoms appear, it is recommended to visit a hospital, improve blood routine, mycoplasma, chest X-ray and other examinations, assist in diagnosis, and guide**. Usually pay attention to a good lifestyle, acute respiratory infection, is to be thorough.

According to the symptoms, the patient should have chronic bronchitis, long-term lung disease or feeling wind and cold, or congenital endowment is insufficient, resulting in lung deprivation, pulmonary ventilation dysfunction, lung qi reversal, so cough and phlegm, shortness of breath, chest tightness, it is recommended to dispel wind and cold, cough and phlegm drugs such as Yangyin Qinglung granules, lung strength cough capsules** It is recommended to give antibiotic drugs such as amoxicillin capsules** to avoid wind and cold.
