Asthma
Asthma is a disease of the respiratory system in which the airways constrict, become inflamed, and are lined with excessive amounts of mucus, often in response to one or more "triggers," such as exposure to an environmental stimulant (or allergen), cold air, exercise, or emotional stress. In children, the most common triggers are viral illnesses such as those that cause the common cold[1]. This airway narrowing causes symptoms such as wheezing, shortness of breath, chest tightness, and coughing, which respond to bronchodilators. Between episodes, most patients feel fine.The disorder is a chronic or recurring inflammatory condition in which the airways develop increased responsiveness to various stimuli, characterized by bronchial hyper-responsiveness, inflammation, increased mucus production, and intermittent airway obstruction. The symptoms of asthma, which can range from mild to life threatening, can usually be controlled with a combination of drugs and lifestyle changes.
Public attention in the developed world has recently focused on
asthma because of its rapidly increasing prevalence, affecting up
to one in four urban children.[2] Susceptibility to asthma can be
explained in part by genetic factors, but no clear pattern of inheritance
has been found. Asthma is a complex disease that is influenced by
multiple genetic, developmental, and environmental factors, which
interact to produce the overall condition.
