Hello. Remember there is no cure for asthma. It is only controllable through medicine. Asthma is more than wheezing. Coughing, recurrent bronchitis and shortness of breath, especially when exercising, are also ways that asthma appears. • The two most common triggers of asthma in children are colds and allergens. • Diagnosing the precise cause of asthma is sometimes difficult because two or more causes may be present in one child. • The most important part of managing asthma is for you and your child to be very knowledgeable about how and when asthma causes problems and how to use medications. • An allergist has specialized training and experience to determine if your child has asthma, what is causing it and develop a treatment plan.
