Your lungs have a branching system of tubes called the bronchial tubes that carry air in and out. Acute bronchitis happens when these tubes become irritated and swollen, usually following a cold or another respiratory infection.
Because the lining of these tubes is inflamed, your body produces extra mucus, which is the thick fluid commonly called phlegm. This irritation makes your body want to cough frequently to clear the tubes, which is why a persistent cough is the most common sign of the condition.
Common Symptoms
- A cough that produces clear, yellow, or green mucus.
- Mild wheezing or a whistling sound when you breathe.
- A slight fever and chills.
- Chest soreness or a tight feeling when you cough.
- Shortness of breath.
