Asthma is a widespread disease that affects many cultures and has no boundaries. It does not care about country, race, religion or sex.

Some common signs and symptoms of asthma are coughing, wheezing and shortness of breath. Asthma is a common long term disease of children, but some adults have asthma too.
Asthma is most common in people under eighteen years of age. Nine million children in America have asthma. It is the most common chronic disease among children and the leading cause of missed school. Children have smaller airways and that makes asthma especially serious for them. Asthma occurs more frequently in boys than girls, the reason being that a boy’s airway size is smaller than a girls. Heredity plays a big role in children getting asthma. It is said that three-fifths of all asthma cases are hereditary. Many things can trigger an asthma attack. Allergens such as mold, pollen or animals, irritants like cigarette smoke or air pollution can all be triggers. Weather such as old air or even sudden changes in the weather can also cause an attack. Exercise is another trigger for an asthma attack. If a child has airway hyper reactivity this is another risk factor for asthma. However not all people who have airway hyper reactivity develop asthma, but if one does have it they have a greater chance of developing asthma.
There are several other ways that children can develop asthma. Atopy which is allergic hypersensitivity is another way that a child can develop asthma. Atopy may include eczema, allergic rhinitis or allergic conjunctivitis. There have been studies done that indicate that 40-50% of children with eczema develop asthma. Indoor air pollutants are a large factor in asthma. Some...
