It is very difficult to diagnose whether the child has asthma or not. In many cases, the child shows symptoms which resemble the onset of asthma, but when observed carefully, the child does not get asthma. Adults may also get asthma.

There are two types of asthma.

1. Extrinsic
2. Intrinsic

Extrinsic asthma is the most common type of asthma seen in asthma patients. Extrinsic asthma develops due to allergies and allergens. Extrinsic asthma develops during childhood, since children are most susceptible to allergies. Most allergies in children are due to hay fever, eczema or family history of allergies.

These allergies disappear as the child grows up and so does asthma, but they may reappear in later stages of life. Intrinsic type of asthma occurs mostly in women who are in their 30s. It is not associated with allergies and intrinsic type of asthma is more chronic and perennial.

The cause of intrinsic asthma can be traced to respiratory tract infections. Asthma also has categorizations based on the intensity of the disease
Asthma can be mild, moderate and severe Mild asthma is found in 30% of the patients.
