How does bronchitis cause

summary

All the inflammation in bronchial mucosa and surrounding tissues can be summarized as bronchitis. The main cause of bronchitis is the repeated infection of bacteria or virus. There are many factors that indirectly lead to bronchitis. For example, when the temperature drops, people's respiratory tract is prone to spasm and ischemia. As a result, the defense ability of respiratory tract is reduced, and bacterial viruses are easy to infect and cause bronchitis. The continuous stimulation of smoke or dust on the bronchus is also easy to cause bronchitis. In addition, air pollution is closely related to bronchitis. Let's take a look at the following.

How does bronchitis cause

First: people who often smoke tend to have bronchospasm, which will also lead to the variation of bronchial mucosa, which will reduce the motor function of the fibrous hairs on the bronchial mucosa, which is not conducive to the self-cleaning of the bronchus, so that bacteria or viruses and some dust fumes can easily adhere to the bronchial mucosa, and then cause inflammation.

Second: the specific bacteria that can cause bronchitis are usually Haemophilus influenzae, Streptococcus and Staphylococcus. The common gases that can cause bronchitis are carbon dioxide, nitrogen dioxide and chlorine. Because allergic bronchitis is more common is fungal spores, pollen, bacterial protein.

Third: the onset of bronchitis may sometimes be caused by allergy, the more typical is allergic bronchitis. In addition, chemical stimulation may also lead to bronchitis. After the onset, patients often cough and cough up sputum. In cold seasons, cold air stimulation may also cause bronchitis.

matters needing attention

Bronchitis has certain genetic factors, such as allergy may be inherited and induce bronchitis. Respiratory immune dysfunction or immune abnormality is also an important cause of bronchitis.
