Asthma is one of the widespread diseases and it affects our airways that carry air to and from our lungs. Asthmatic is what we call those people who experience long-lasting or recurrent sufferings of this disease.
An asthmatic person has swollen or inflamed inside walls which makes the airways extremely sensitive to irritations and increases the susceptibility to allergic reactions.
If the airways become closer and narrower, there is a small amount of air that can pass through them, both to and from the lungs. There are symptoms of the narrowing that include wheezing, chest tightness, breathing problems, and coughing.
