Bronchitis Symptoms

The hallmark of bronchitis is a cough that brings up mucus. Everything else clusters around it. Knowing the ordinary course - and the red flags that break the pattern - tells you when to wait and when to see a doctor.

Acute bronchitis: the typical picture

• Cough: the dominant symptom - dry at first, then productive within a few days
• Mucus (sputum): clear, white, yellow or green. Colored mucus alone does NOT mean bacterial infection - it is your immune cells doing their job, not an automatic antibiotic signal
• Chest discomfort: a raw, sore feeling behind the breastbone, worse with coughing
• Wheeze and mild breathlessness: from narrowed, mucus-coated airways
• Low fever, body ache, sore throat, runny nose: the cold it rode in on
• Course: most symptoms settle in 7-10 days; the cough itself commonly lingers 3 weeks, sometimes up to 8 - an annoying but normal tail

Chronic bronchitis: the long pattern

• Daily mucus cough, most mornings, for months every year
• Gradually increasing breathlessness - first on exertion, then at rest
• Frequent "chest colds" that hit harder and last longer than other people's
• Wheeze, chest tightness, fatigue

Red flags - see a doctor promptly

• High fever (above 100.4 F / 38 C) or fever lasting beyond 3 days - suggests pneumonia or flu, not simple bronchitis
• Breathlessness at rest, rapid breathing, chest pain
• Blood in the mucus
• Cough beyond 3 weeks, or one that keeps getting worse instead of better
• Symptoms in someone with asthma, COPD, heart disease, diabetes, or weak immunity; in adults over 65; in infants
• Bluish lips or confusion - an emergency: call 112 / 102

The classical note

Classical texts separated coughs by their texture - dry and hacking (Vataja Kasa), burning with yellow sputum (Pittaja), heavy with thick white mucus (Kaphaja), the cough of chest injury (Kshataja), and the wasting cough (Kshayaja). The useful instinct: a cough's character and company (fever, weight loss, blood) matter as much as its presence.

One-line summary

A mucusy cough after a cold that improves over 1-3 weeks is ordinary bronchitis; high fever, breathlessness, blood, or a cough that overstays 3 weeks is a doctor's visit.
