(HealthDay News) -- Bronchitis is an inflammation of the bronchial tube lining, says Mayo Clinic. People who have bronchitis often cough up thick, discolored mucus. Though complications are rare, bronchitis can lead to pneumonia in some people.
To help prevent bronchitis, Mayo suggests:
Avoid cigarette smoke.
Get vaccinated for flu.
Wash your hands regularly.
Mayo also reminds people to wear a surgical mask if they have chronic obstructive pulmonary disease.
