What Is Allergic Asthma
Asthma is a chronic condition whose main symptom is shortness of breath. This symptom can be caused by several factors including, but not limited to, the airways becoming narrowed or inflamed and the accumulation of mucus in the lungs. Asthma usually runs through the genes but it may also be developed, especially if the person is exposed for an extended period of time in environments that may cause respiratory infections.
