If you have chronic bronchitis, your airways are inflamed and narrowed. The narrowing of the airways affects how well and how easily air is emptied out of your lungs.
Bronchitis can be short-term (acute) and long-term (chronic). In COPD, bronchitis is chronic. You can more about acute bronchitis inflammation on the NHS website.
Symptoms of chronic bronchitis include:
- a continuous cough that produces phlegm (mucus) – according to the NHS, this is defined as a daily cough for three months of the year, for two or more years in a row
People with chronic bronchitis often develop emphysema – when the air sacs in the lungs are damaged.
