Bronchitis

From Wikipedia, the free encyclopedia

Bronchitis is an inflammation of the bronchi.

More specifically, it may refer to:

• Acute bronchitis, caused by viruses or bacteria and lasting several days or weeks
• Chronic bronchitis, a persistent, productive cough lasting at least three months in two consecutive years.

In bronchitis, the membranes lining the larger bronchial tubes become inflamed and an excessive amount of mucus is produced. The person with bronchitis develops a bad cough to get rid of the mucus.
