Asthma is one of the most common chronic diseases in the world. Perhaps the most commonly discussed respiratory disease after the common cold. The word asthma is derived from a Greek work meaning 'breathlessness or panting" both of which accurately describe an attack of asthma.

Asthma is a condition that affects airways the small tubes that carry air in and out of the lungs.

How does it occur?

In children with asthma, airways are swollen and inflamed. When these inflamed airways come into contact with an asthma trigger, symptoms of asthma appear.
