Bronchitis
Bronchitis refers to an inflammation of the mucous membrane lining the bronchi and bronchial tube within the chest. It is a breathing disorder affecting the expiratory function. In most cases, some infection also occurs in the nose and throat. It is a disease endemic to cold, damp climates, but may occur anywhere.

Bronchitis may be acute or chronic. In chronic cases, the disease is of long duration. It is more serious than the acute type as permanent changes may have occurred in the lungs, thereby interfering with their normal movements. Chronic bronchitis is more frequent in males than in females and mortality rate is also higher in males.

Symptoms
In most cases of bronchitis, the larynx, trachea and bronchial tubes are acutely inflamed. The tissues are swollen due to irritation. Large quantities of mucus are secreted and poured into the windpipe to protect the inflamed mucous membrane. The phlegm, when expelled is found to be viscid and purulent. There is usually a higher fever, some difficulty in breathing and a deep chest cough. Other symptoms are hoarseness and pain in the chest and loss of appetite. Breathing trouble continues until the inflammation subsides and mucous is removed.

Causes
The chief cause of bronchitis is wrong feeding habits. The habitual use of refined foods such as white sugar, refined cereals, and white-flour products results in the accumulation of morbid mater in the system and collection of toxic waste in the bronchial tube. Another important cause of this disease is smoking. Excessive smoking irritates the bronchial tubes and lowers their resistance so that they become vulnerable to germs breathed in from the atmosphere. Other causes of bronchitis are living or working in a stuffy atmosphere, use of drugs to suppress earlier diseases and hereditary factors. Changes in weather and environment are common factors for the onset of the disease.
