Katie is a 16-year-old high school student who is a very good soccer player. She is currently playing on her high school team and a traveling squad of All-Stars. In the last 6 months, Katie has begun having excessive shortness of breath with wheezing while playing soccer. Symptoms are worse when she is playing a match but she also notes similar symptoms during practice. She has had one recent episode which was sufficiently severe and caused her to faint. Katie has seen her family physician and he has suggested that she may have exercise – induced bronchospasm (EIB). She has tried treating with inhaler prior to exercise however this medication has been ineffective and the symptoms continue.
