Asthma is a breathing condition characterized by intermittent wheezing, shortness of breath, and widespread narrowing of the airways. It may abate either spontaneously or as a result of treatment. One characteristic feature of asthma is inflammation of the airways, resulting in swelling of the lining of the bronchi in hyper-responsiveness (which is an exaggerated airway narrowing). The inflammatory changes may be triggered or caused by extrinsic factors such as dust, pollen, animal dander, molds, and other allergens. The airway hyper-responsiveness may be triggered by the above, and in addition exercise, stress, and cold dry air. There are a number of cases of asthma that are not brought on by any presently known external factors. This type of asthma is called intrinsic asthma, and it is also known as late-life asthma. Heredity, including allergies and certain occupational causes of asthma are also important.

Diseases Which May Complicate COPD

• Cancer of the lung

• It is well-known that cancer and COPD are closely related. It has now been shown that patients with air flow obstruction have a higher incidence of cancer of the lung than those without obstruction.

• Heart disease

• Pneumonia

• Pneumothorax (collapsed lung)

• Sleep disorders

• Pulmonary embolism (blood clot in the lung)
