It is estimated that 1 out of 20 people have asthma, but 1 out of 10 children have it. Asthma is a disease where no apparent reason can be given for its surfacing. It is intrinsic. Asthma usually goes away with age, but it can occur in adults of any age. The most common type of asthma is allergic bronchial asthma it is usually caused by allergies.

In severe or acute cases steroids, nedocromil sodium, or cromolyn sodium may be used, as well as oxygen treatments and hospitalization may be necessary. Although medication is very helpful in the treatment of asthma, it is still an incurable disease. But with proper care, such as staying away from known allergens, pets, and cigarette smoke, a person can lead a almost normal life.
