A common cause for asthma symptoms is exercise. But even if you have asthma you can still engage in sports as long as you work at controlling your asthma and are aware of the limitations that sporting organizations may place on your asthma medicines. If you really want to be in sports you cannot simply disregard it.
Just like a sterling silver cuff, it is something that is precious to you. Check the status of your medicines in the sport or competition you are entered in by asking your doctor to thoroughly check all your prescribed medicines and by contacting the World Anti-Doping Agency if you are joining an international competition.
