10 Causes of Pneumonia

6. Bronchitis

Although we have already discussed how bacteria is the primary cause of pneumonia, there is one bacterial condition that does deserve a special mention: bronchitis. Bronchitis is a condition caused when the bronchial tubes in the lungs become inflamed, creating a multitude of symptoms, most significantly a rattling, telltale "hacking" sound. When this bacterial infection goes untreated, or when the bacteria begin to multiply, bacterial pneumonia can readily develop. This is why it is extremely important to diagnose and treat bronchitis as early as possible.
