This allergy form of the disease is the easiest to diagnose for some physicians as they do commonly utilize the theories of the pathophysiology of asthma.  If a patient goes to the suggesting they have been experiencing a series of asthma attacks that only seem to occur when they are around fresh cut grass, then obviously the doctor will suggest keeping way from it as much as possible.  The allergy form can also be categorized for those who suffer attacks as a reaction from a food allergy.  An allergen can come in the form of food or what is in your environment, such as fumes, flowers, dust, mold or pet dander.  Most people are aware if for example they are allergic to certain forms of pet dander, but they don't automatically direct their asthma attacks with that allergy until they have a physician make it more clear for them.  Allergy induced asthma is very crucial to diagnose for little ones suffering attacks so the parents can seek treatment before the child goes to school, has an attack and doesn't know what to do to stop it.  Some parents even pull their little ones out of playing team sports thinking it is just too much for the child with their attacks, with the real reason for the attacks developing is from an allergy they come into contact with outside.  In that case, the child can just be put on allergy medicine to block those histamines and continue playing sports and enjoying being a child.  If you or your child still experience attacks rather frequently after seeking some form of treatment, then do seek the advice of a specialist.
