What is pathophysiology of chronic bronchitis?
Pathophysiology. Chronic bronchitis is thought to be caused by overproduction and hypersecretion of mucus by goblet cells. Epithelial cells lining the airway response to toxic, infectious stimuli by releasing inflammatory mediators and eg pro-inflammatory cytokines.
Is chronic bronchitis recurrent?
Chronic bronchitis is a more serious condition that develops over time rather than striking suddenly. It’s characterized by recurrent episodes of bronchitis that last for several months or years.
What causes recurring bronchitis?
What causes chronic bronchitis? The cause of chronic bronchitis is usually long-term exposure to irritants that damage your lungs and airways. In the United States, cigarette smoke is the main cause.

What are the differential diagnosis for bronchitis?
Differential Diagnosis of Acute Bronchitis
| Disease process | Signs and symptoms |
|---|---|
| Reactive airway disease | |
| Asthma | Evidence of reversible airway obstruction even when not infected |
| Allergic aspergillosis | Transient pulmonary infiltrates |
| Eosinophilia in sputum and peripheral blood smear |

Does chronic bronchitis ever go away?
Unlike acute bronchitis, which usually develops from a respiratory infection such as a cold and goes away in a week or two, chronic bronchitis is a more serious condition that develops over time. Symptoms may get better or worse, but they will never completely go away.
How do you permanently cure chronic bronchitis?
There is no cure for chronic bronchitis, and treatment is aimed at reducing symptoms and improving lung function.
- Medications to help suppress the cough or loosen and clear secretions may be helpful.
- Bronchodilator inhalers will help open airways and decrease wheezing.
How do you diagnose chronic bronchitis?
Chest X-ray — Chest X-rays can help confirm a diagnosis of chronic bronchitis and rule out other lung problems. Sputum Examination — Analysis of cells in your sputum (mucus) can help pinpoint the cause of some lung problems.
What is the difference between bronchitis and bronchospasm?
Bronchospasm is an abnormal contraction of the smooth muscle of the bronchi, resulting in an acute narrowing and obstruction of the respiratory airway. A cough with generalized wheezing usually indicates this condition. Bronchospasm is a chief characteristic of asthma and bronchitis.
