Sist oppdatert: Sist revidert:
Sist revidert av:
Definisjon: 
Er en forbigående og reversibel luftveisobstruksjon som vanligvis oppstår innen kort tid etter fysisk anstrengelse hos en person med eller uten underliggende astma
Forekomst: 
Forekommer først og fremst blant individer som driver med utholdenhetsidretter som krever høy minuttventilasjon. Miljøfaktorer som tørr luft, kulde, allergener og stoffer som irriterer luftveiene kan forverre tilstanden 
Symptomer: 
Kortpustet, tetthet i brystet, hoste eller hvesing umiddelbart etter eller noen ganger under intens fysisk utholdenhetsaktivitet
Funn: 
I akuttfasen foreligger takypné og pipelyder under ekspirasjon. Etter 60 min. hvile normale funn
Diagnostikk: 
Tilleggsundersøkelser er spirometri utført i hvile og etter belastning  
Behandling:
Oppmuntre til regelmessig fysisk aktivitet. Hurtigvirkende bronkodilaterende medisin (kortidsvirkende β2-agonist eller ICS-formoterol) og oppvarming før hard aktivitet. Gradvis reduksjon av belastning etter hard aktivitet Obs WADAs dopingregler
