Bronchitis is usually considered as an inflammation of bronchial tube lining. Bronchial tubes are responsible to carry air to your lungs. Bronchitis generally results in production of thickened mucus while coughing. Bronchitis can either be acute or chronic.

Acute bronchitis is very common due to the common cold, fever and respiratory tract infections. Chronic bronchitis is a serious condition that causes irritation or inflammation of the bronchial tube lining. Acute bronchitis can be cured in few days whereas; chronic bronchitis requires immediate medical attention and takes a longer time to recover completely.
