What are the symptoms of bronchitis?
Bronchitis causes a persistent cough that may be dry or bring up clear, white, yellow, or green mucus, often with chest tightness, wheezing, fatigue, and sometimes a low-grade fever. The cough typically lasts one to three weeks.
Bronchitis is inflammation of the bronchial tubes, the airways that carry air to your lungs. When they swell and produce extra mucus, the result is the hallmark cough that defines the illness. Here is what the full symptom picture usually looks like and what each sign is telling you.
The Core Symptoms
- Persistent cough — the main feature. It may be dry or bring up mucus that is clear, white, yellow, or green. Color alone does not mean you need antibiotics; it simply reflects the immune response.
- Chest discomfort or tightness — a sore, heavy feeling in the chest, usually from the repeated coughing rather than a heart problem.
- Mucus (sputum) production — your airways clearing themselves as they recover.
- Wheezing — a whistling sound as air moves through narrowed, inflamed airways.
- Shortness of breath with activity — feeling winded going up stairs, more noticeable when the infection is at its peak.
- Low-grade fever and chills — a mild fever is common and expected.
- Fatigue — feeling run down while your body fights the infection.
- Sore throat and runny nose — common early on, because acute bronchitis often follows a cold or other viral upper respiratory infection.
What the Timeline Tells You
Acute bronchitis symptoms usually build over a few days and improve within one to three weeks, though the dry cough can linger a while after everything else clears. A cough that keeps returning over months or seasons may point to chronic bronchitis, which is a different, longer-term condition often linked to smoking.
Which Symptoms Are Dangerous
Most of the symptoms above are uncomfortable but expected. A different set of symptoms means the illness may no longer be simple bronchitis:
- Trouble breathing at rest, fast breathing, or bluish lips — signs of low oxygen
- A high fever above 102 F, one lasting more than three days, or shaking chills — a clue the infection may have become pneumonia
- Chest pain when you breathe in, feeling much sicker rather than better, or coughing up blood
These warning signs mean the lung tissue itself, not just the airways, may be involved, and they warrant prompt evaluation.
