Not every type or intensity of exercise affects kids with EIA the same way. If exercise is the only asthma trigger, the doctor may prescribe a medication that the child takes prior to exercising to prevent the airways from constricting. Even if the primary triggers are colds or exercise, allergies usually play a role in aggravating the condition. The IgE antibody senses small quantities of allergens such as dust mites and molds and generates allergic reactions to these usually harmless particles. When allergens enter the body, they attach to the IgE antibody, which causes mast cells to release histamine to defend against the allergen invader.
Histamine is what causes the sneezing, runny nose, and watery eyes associated with most allergies.
These are the ways the body attempts to rid itself of the invading allergen. In a child with asthma, histamine can also trigger asthma symptoms. An allergist can usually identify any allergies a person has. Clearing allergens out of the home can help reduce asthma attacks. When allergens can't be avoided, antihistamine medications help to block the release of histamine in the body.
