Bronchitis is an inflammation of the lining of tubes that carry air to and from your lungs. People who have bronchitis often have a cough that brings up thickened, discolored mucus. They may also have wheezing, chest pain, and shortness of breath.
Chronic bronchitis is a form that develops over time rather. There are many bouts of bronchitis that last for several months or years. The constant inflammation in the airway cause increased level of sticky mucus. This makes it harder for air to move into and out of the lungs. The airflow gets worse over time.

- Long-term exposure to chemicals, dust, and other substances that have been inhaled
- Long-term cigar or marijuana smoking
- Exposure to secondhand smoke
- Family members with COPD
- History of frequent childhood lung infections
