What is Bronchitis

What is Bronchitis

Bronchitis occurs when the lining of small tubes that connect the windpipe with the lungs gets inflamed. When these tubes, the bronchi, are inflamed, less air is able to flow to and from the lungs and a heavy mucus is coughed up. Some people have bronchitis with a bad cold, but their symptoms go away when the cold is over. This is called acute bronchitis. Persistent, or chronic, bronchitis does not go away. The airways become narrower, making it difficult to breathe.
