It was during the 1800s that this condition causing the inflammation of bronchial mucous membranes came to be known. Further clinical studies have enabled detailed information on the causes, symptoms and treatment of Acute Bronchitis.

Inflammation of the main air passages to the lungs (called the bronchi) and the complications related to it, collectively lead to the condition called Acute Bronchitis. During Acute Bronchitis, sticky mucus fills up the bronchi causing them to swell up. This inflammation impedes the flow of air in and out of the lungs, causing great discomfort to patients.

The inflammation of the bronchi is in response to the virus attack on the air passage. This triggers bronchial epithelial injury leading to the said condition.

Bronchitis could take on a chronic form, also called Chronic Bronchitis. The distinguishing feature between Acute Bronchitis and Chronic Bronchitis lies in the duration of the condition - Acute Bronchitis could leave its victims 'under weather' for a brief period;in contrast, Chronic Bronchitis could last a lifetime.

This is a condition that is usually ignored by people. Occasionally this condition can cause severe damage to the air passages of the lungs.
