Understanding the Tell-Tale Cough in Acute Bronchitis
Published: Sep 29, 2023
The persistent cough in acute bronchitis is more than just an annoyance. Understanding this symptom can help in managing the condition effectively.
Characteristics of the Cough
The cough in acute bronchitis often starts abruptly and can last for one to three weeks. It may be dry or produce mucus, and can be accompanied by wheezing or mild shortness of breath. Recognizing these characteristics helps differentiate it from other respiratory issues.
Why the Cough Persists
The cough is caused by inflammation of the airways due to a viral infection. This inflammation can lead to temporary bronchial hyperreactivity, making the cough linger even after the initial infection clears. Knowing this can reassure patients that the cough will eventually resolve.
When to Be Concerned
While the cough is usually harmless, if it is accompanied by high fever, chest pain, or persists beyond three weeks, it may indicate a more serious problem like pneumonia. These signs warrant medical evaluation to rule out other conditions.
