Exercise-Induced Bronchoconstriction Defined

Exercise-Induced Bronchoconstriction, (EIB), often known as exercise-induced asthma, is a narrowing of the airways causing difficulty moving air out of the lungs during exercise.

If you have chronic asthma, your symptoms may be worse when you exercise. Yet some people who don’t have asthma experience symptoms only when they exercise.

Symptoms include: 
• Shortness of breath
• Coughing
• Wheezing
• Tight chest

These symptoms are often worse in cold, dry air. Warm and humid air may lessen the symptoms.

Exercise is a very important aspect of good health, so your allergist / immunologist may prescribe taking medication prior to exercising to control symptoms.

If you or your child has symptoms of EIB, an allergist / immunologist, often referred to as an allergist, can help. An allergist has advanced training and experience to determine what is causing your symptoms and develop a treatment plan to help you feel better and live better.
