Exercise-induced asthma is when the airways narrow or squeeze during hard physical activity. It causes shortness of breath, wheezing, coughing, and other symptoms during or after exercise. The medical term for this condition is exercise-induced bronchoconstriction (brong-koh-kun-STRIK-shun).
The exercise needs to be intense enough to trigger your symptoms. If needed, you might be asked to perform a real-life exercise challenge, such as climbing stairs. Spirometry tests before and after the challenge can provide evidence of exercise-induced bronchoconstriction.
For some people, asthma signs and symptoms flare up in certain situations: Exercise-induced asthma, which may be worse when the air is cold and dry; Occupational asthma, triggered by workplace irritants such as chemical fumes, gases or dust
Though allergic asthma is very common, there are other types of asthma with different kinds of triggers. For some people, asthma can be triggered by exercise, infections, cold air, gastroesophageal reflux disease or stress. Many people have more than one kind of asthma trigger.
Regular exercise can strengthen your heart and lungs, which helps relieve asthma symptoms. If you exercise in cold temperatures, wear a face mask to warm the air you breathe. Maintain a healthy weight.
There's no asthma diet that will eliminate your symptoms. But these steps may help: Eat to maintain a healthy weight. Being overweight can worsen asthma. Even losing a little weight can improve your symptoms. Learn how to eat right to maintain a healthy weight over the long term. Eat plenty of fruits and vegetables.
It isn't clear why, but it's known that acid reflux can worsen asthma and asthma can worsen acid reflux — especially severe acid reflux, a condition known as gastroesophageal reflux disease (GERD). Asthma and acid reflux can occur together in children as well as in adults.
Cardiac asthma is not a form of asthma. It's a type of coughing or wheezing that occurs with left heart failure. Depending on how severe the symptoms are, this wheezing can be a medical emergency. Heart failure can cause fluid to build up in the lungs, a condition called pulmonary edema.
Inflammation is defined as swelling and other changes in airway tissues caused by immune system activity. These changes narrow the airways and make it difficult to breathe. With occupational asthma, lung inflammation may be triggered by a substance that a person is allergic to, such as mold or an animal protein.
If you appear to have asthma triggered by exercise, called exercise-induced asthma, you may be asked to do physical activity to see whether it triggers symptoms. After either action, you'll retake the spirometry test.
