An allergist can determine whether your symptoms are exercise-induced alone, are a reaction to allergens or irritants in the air, or are an indication of underlying asthma. Wheezing in children after physical activity is often the first symptom of asthma.
As part of an examination, your allergist will take a history (including asking for information about any relatives with asthma or other breathing difficulties).
You also may be asked for specific details about your physical activity, including where and how often you exercise. Your allergist will consider contributing or complicating conditions, such as upper-airway problems, that might play a role in your difficulties with exercise.
To check how exercise affects your breathing, your allergist may measure your breathing before, during and after you run on a treadmill or ride an exercise bike. During the test you will breathe into a tube that connects to a spirometer, a device that measures the volume of air being inhaled and exhaled.
In some cases, environmental factors may contribute to EIB.
Skaters and hockey players may be affected by a combination of cold, dry air in ice rinks and pollutants from ice-resurfacing machines, while EIB in distance runners has been linked to exercising in high-allergen and high-ozone environments. In addition, metered indoor air with high levels of trichloramine, a chemical used in pool chlorination, has been linked to asthma and EIB in swimmers.
People with exercise - induced asthma often start.
