What if the treatment of bronchitis is not timely?

Why do middle-aged and elderly people become a high-risk group of bronchitis? In addition to the environmental factors such as environmental deterioration and air pollution, there are many human factors. Among them, smoking is one of the biggest factors. So what is the relationship between bronchitis and smoking?

What if the treatment of bronchitis is not timely?

How does smoking induce bronchitis?

Smoke contains a variety of harmful substances, including tar, carbon monoxide, nitrogen monoxide, hydrogen cyanide, acrolein and nicotine. Animal experiments have shown that after inhalation of smoke, nerve excitability increases, bronchial smooth muscle spasm; respiratory mucosal cilia movement ability is weakened; bronchial submucosal gland cells increase, hypertrophy, excessive secretion of mucus, weakening the cleansing effect of the respiratory tract; bronchial mucosa congestion, edema The function of phagocytic cells in the lung cells is weakened, which may easily lead to infection of the bacteria.

Similarly, people who smoke regularly, bronchial mucosa epithelial cilia fall off, mucous gland hyperplasia, bronchospasm, susceptible to bacterial infection. Autopsy found that all smokers had small bronchial changes, mainly manifested as bronchial mucosal damage, inflammation of the wall, especially small bronchial inflammation; mucosal edema, fibrosis, increased secretion of mucous gland cells. Thereby inducing bronchitis.


The treatment of bronchitis does not become a hidden danger of many diseases in time.

Not only is the disease itself affecting health, after 5 years, if it is not clearly controlled, there will be complications such as obstructive emphysema, pneumonia, bronchial pneumonia, and bronchiectasis. After 8 to 10 years, these comorbidities can prevail, threatening human health and even life.


In addition, long-term prolonged prolonged bronchitis can lead to the occurrence of chronic bronchitis, causing other diseases during the course of the disease, such as lung infection, pneumonia, bacteremia, etc., acute exacerbations of the disease often have sinister risks. Because the condition of chronic bronchitis can be delayed for several years or decades, elderly patients are more common. The lung infection and pneumonia caused by chronic bronchitis pose a serious threat to the health and longevity of the elderly.
