Bronchitis is defined as a disease with acute inflammation of the respiratory tract. The term is basically coined from the Greek words bronchos, which means windpipe, and itis, meaning inflammation. Bronchitis takes place when the trachea or windpipe and the bronchi (both small and large) become inflamed which is likely caused by an infection or other factors.

Bronchitis has two types, acute and chronic. Acute bronchitis is mainly caused by viral or bacterial infections and from the acute word itself, it is only for a short period of time, but that is another story.

Chronic bronchitis, on the other hand, is a long term bronchial inflammation consequently followed by a raise in the production of mucus. It is also a type of chronic obstructive pulmonary disease (COPD), which is a group of respiratory diseases that hampers with normal breathing.

Chronic bronchitis can be caused by no specific factor but cigarette smoking is believed to be the major culprit of the illness. Following smoking, other causes may include environmental pollution (especially air pollution) and bacterial or viral infections.

To be considered as chronic bronchitis, the patient must experience cough and expectorations (meaning with phlegm or sputum) for no less than 3 months in a year for two successive years. Furthermore, other factors that may cause symptoms such as TB (tuberculosis) or other respiratory health problems must be excluded.

As a category of COPD, primary symptoms of chronic bronchitis are mucus expectoration, cough, and dyspnea or labored breathing during physical exertion. These symptoms commonly deteriorate over time. Persistent cough and mucus expectoration usually come first years before the development of aberrations in the airflow of the respiratory tract.

Dyspnea or labored breathing, due to its severity, more often than not causes interference in the patient’s day to day activities. Loss of weight is fairly not uncommon since eating needs a certain amount of physical exertion and the sometimes only breathing itself can be energy consuming for the patient.

There will come a time when the patient will find it difficult to even participate in mild exercise because of dyspnea. As bronchitis progresses, labored breathing will be experienced by the patient even at rest. Then the patient will become in danger of acquiring more respiratory infections and respiratory insufficiency, which consequently raises the danger for both chronic and acute respiratory failure.

Other warning signs of chronic bronchitis may include swelling of the feet, abnormal lung signs, heart failure, and bluish discoloration of the lips and skin.
Symptoms may be similar to other respiratory problems; therefore it is advisable that the patient should consult a physician. This is due to the fact that chronic bronchitis is frequently associated with other diseases of the respiratory system such as asthma, tuberculosis, sinusitis, pulmonary emphysema, and other upper respiratory infections.
