How is bronchitis caused?

Both biological and abiotic factors can lead to bronchitis. Among them, virus infection

This is one of the most common reasons, and a few patients may have bacterial infection.

Situation.

Biological factors such as age and immunity may affect the onset or acute exacerbation of bronchitis and mycoplasma.

Or chlamydia infection

It can also lead to bronchitis.

Abiotic factors, including seasonal changes, cold air, dust, irritating gases (or particles), smoke inhalation, etc. , can lead to bronchial mucosal injury and inflammatory reaction.

What are the causes of bronchitis?

Acute bronchitis

The common cause is microorganism, virus infection is the most common, and other microbial factors include bacteria and chlamydia pneumoniae.

And mycoplasma pneumoniae

Wait;

Inhalation of cold air, dust, irritating gas or smoke can stimulate the trachea-bronchial mucosa, causing acute injury and inflammatory reaction;

Common inhaled allergens, such as pollen, organic dust, fungal spores, animal fur excretions, and allergies to bacterial proteins, hookworms and roundworms.

The migration of larvae in the lungs can cause acute tracheobronchitis.

chronic bronchitis

The etiology is not completely clear, which may be the result of long-term interaction of many factors. Viral, bacterial and mycoplasma infections

Is one of the important reasons for its occurrence and development. Inhalation of harmful gases and particles, immunity, age and climate are also important factors for the occurrence and development of chronic bronchitis.

capillary angioma

It is mainly caused by viruses of bronchial epithelial cells, among which respiratory syncytial virus is the most common, accounting for more than 50%, and it is also the most likely pathogen to cause severe diseases, which can cause outbreaks and great harm.

Acute bronchiolitis is mainly seen in infants under 65,438+0 years old, living environment where people gather, tropical rainy season, no breastfeeding or breastfeeding for less than 65,438+0 months, age less than 65,438+02 weeks, bottle feeding, smoking addiction during pregnancy and premature delivery.

, suffering from heart and lung disease or low resistance are all hidden danger factors.

Bronchiolitis obliterans

There are many possible reasons, including rejection after organ transplantation.

Connective tissue disease

, virus infection, Qiang Sen's syndrome, pneumocystis pneumonia.

Wait a minute. Non-transplant-related bronchiolitis obliterans is rare. Sometimes bronchiolitis obliterans also refers to severe bronchiolitis in children caused by adenovirus infection.
