What is Exercise-Induced Laryngeal Obstruction?
Introduction Exercise-induced laryngeal obstruction (EILO) is a transient, reversible narrowing of the larynx that occurs during high intensity exercise. This acts to impair airflow and cause shortness of breath, stridor and often discomfort in the throat and upper chest. EILO is a very common cause of breathing difficulties in young athletic individuals but is often misdiagnosed as asthma or…
What is Exercise-Induced Bronchoconstriction?
Introduction Exercise-induced bronchoconstriction (EIB) occurs when the airways narrow as a result of exercise. This condition has been referred to as exercise-induced asthma (EIA); however, this term is no longer preferred. While exercise does not cause asthma, it is frequently an asthma trigger. It might be expected that people with EIB would present with shortness of breath, and/or an…
Wheezing while working out? It could be exercise-induced bronchoconstriction
It's normal to feel a little out of breath after a round of strenuous exercise. However, if a person experiences tightening of the chest, coughing, wheezing, and extreme fatigue during or after a workout, it could be exercise-induced bronchoconstriction (EIB.)
EIA used to be called exercise-induced asthma (EIA) because sufferers of EIB experience many of the same symptoms as those with true asthma. People who have asthma, as well as people who don't, can have EIB.

EIB causes
When a person breathes, he normally takes in air through his nose. The nasal passages warm and moisten the air inhaled. However, when a person exercises strenuously, he tends to take quick, shallow breaths through his mouth. The mouth isn't as effective at moistening inhaled air as the nose.
The air he breathes in is cooler and drier than it would've been had he inhaled through his nose. The coldness and dryness of the inhaled air trigger bronchoconstriction or the narrowing of the airways. This makes it difficult to move in and air out of the lungs during exercise.
EIB is often worse when a person exercises in cold, dry weather. Other triggers of EIB include allergens such as dust and pollen and respiratory infections.

Getting a diagnosis
Diagnosing EIB is made difficult by the fact that its symptoms are often mistaken for the natural response of the body to unaccustomed exercise. The symptoms of EIB are also shared by various other medical conditions, such as cardiac arrhythmias and gastroesophageal reflux disease (GERD.)
To diagnose EIB, the doctor will administer a spirometry test to measure the patient's lung function at rest. This test serves to rule out underlying conditions, such as asthma or some other lung condition.
The doctor could order more diagnostic tests if the results of the spirometry are inconclusive. An exercise test, during which the patient will be asked to perform a strenuous exercise, allows the doctor to observe the patient's symptoms as they are triggered.
With the proper treatment, patients with EIB can prevent or lessen the severity of EIB symptoms and continue exercising.
Robert R. Beltran, M.D., is an otolaryngologist with more than 30 years of experience treating conditions of the eyes, ears, and neck. For more discussions on EIB, like this Facebook page.
I have Exercise-induced bronchoconstriction (exercise-induced asthma or sports asthma) so it's really hard to exercise. So when someone tell me "you need to lose weight" I get really pissed. When you have EIA your airways constrict when you have to breath hard (running mostly for me). PE was hell for me because we had to do this thing called "The Indian Run" (racist as hell, I know) where everyone in the class lines up on the red out of bounds line on the basketball court and we start running and then where we do a lap the person in front goes to the back of the line then repeat for 25-30 times depending on the number of kids in the class. Because the leader would set the speed we had jocks that would go at full speed and I'd have a massive EIA attack and the PE teacher who was also the football coach and is mandated by universal law to be a massive cum stain would tell at me for ducking out and trying to breath. FUCK RUNNING AND FUCK FATSHAMEING. Just because I can run doesn't mean I won't trip you and apply my 210 pound ass to your neck.
