What is exercise-induced bronchospasm (EIB)?
Exercise-induced bronchospasm (EIB) happens when the airways in your lungs narrow when you exercise. This makes it hard to breathe. If you have EIB, it may be hard to exercise for more than 30 minutes at a time. EIB also is called exercise-induced bronchoconstriction. It is the same thing as exercise-induced asthma.
What are the symptoms of bronchospasm caused by exercise?
Exercise-Induced Bronchospasm Symptoms. 1 Coughing. 2 Difficulty breathing. 3 Wheezing (a distinct breathing noise that indicates distress and is also common in asthma) 4 Fatigue and decreased athletic performance. 5 Chest tightness.
What is the difference between exercise-induced asthma and exercised bronchospasm?
Exercise-induced bronchospasm (EIB) and exercise-induced asthma are often described as being the same condition. However, despite similar symptoms more recent research suggests that they are actually separate conditions. Individuals with exercise-induced asthma typically suffer from underlying asthma. This is not the case with EIB.
What can cause bronchospasm?
Any swelling or irritation in your airways can cause bronchospasm. This condition commonly affects people with asthma. Other factors that can contribute to bronchospasm include: To diagnose bronchospasm, you can see your primary care doctor or a pulmonologist (a doctor who treats lung diseases).
What causes exercise-induced bronchoconstriction?
EIB is caused by the loss of heat, water or both from the airways during exercise when quickly breathing in air that is drier than what is already in the body. Symptoms typically appear within a few minutes after you start exercising and may continue for 10 to 15 minutes after you finish your workout.

How do you test for EIB?
A spirometry breathing test is done before and after you exercise on a treadmill. Spirometry can show how much air you can breathe in and out. It also shows how fast you can breathe in and out. The spirometry results are compared before and after you exercise to see what changes there are in your breathing.
Which inhaler is best for exercise-induced asthma?
The gold standard of exercised-induced asthma treatment is a prescription albuterol inhaler. You can carry it with you and use it about 15 to 20 minutes before exercise to prevent asthma symptoms. It's an effective treatment for about 80 percent of exercise-induced asthma cases.

What causes bronchoconstriction in asthma?
Mast cells. Mast cells are also important in the pathophysiology of asthma. Activated mast cells release histamine and other inflammatory mediators that cause bronchoconstriction and the recruitment of immune cells to the airway (109).
What medication causes bronchospasm?
The major categories of medications known to induce bronchospasm or cough, including beta-blockers, cholinesterase inhibitors, angiotensin-converting enzyme inhibitors, and inhalational agents are reviewed.
What is an acute bronchospasm?
Bronchospasm is an abnormal contraction of the smooth muscle of the bronchi, resulting in an acute narrowing and obstruction of the respiratory airway. A cough with generalized wheezing usually indicates this condition. Bronchospasm is a chief characteristic of asthma and bronchitis.
What is the difference between bronchospasm and bronchoconstriction?
Abstract. Bronchospasm is a common diagnosis during anesthesia but it is rarely the correct one. Bronchoconstriction or narrowing of airways from loss of lung volume is a far more common cause of wheezing and difficulty with ventilation during anesthesia.
What is exercise-induced bronchospasm?
Exercise-induced bronchospasm (EIB) happens when the airways in your lungs narrow when you exercise. This makes it hard to breathe. If you have EIB, it may be hard to exercise for more than 30 minutes at a time.
How long does it take for bronchospasm to start?
Symptoms of exercise-induced bronchospasm. Symptoms of EIB start after about 5 to 20 minutes of non-stop exercise. The length of time depends on how severe your condition is. Symptoms can include:
Why is EIB worse in the spring?
For others, breathing in air that is cooler and drier than the air in your lungs causes EIB. If you have EIB and chronic asthma, your symptoms may be worse in the spring and fall. This is when people have more trouble with allergies.
How to tell if you have EIB?
Symptoms of EIB start after about 5 to 20 minutes of non-stop exercise. The length of time depends on how severe your condition is. Symptoms can include: 1 trouble breathing 2 coughing 3 chest pain 4 chest tightness 5 wheezing (breathing that makes a hoarse, squeaky, or whistling sound)
What does a doctor do for a spirometer?
The doctor will do a physical exam and review your symptoms. They likely will perform breathing tests as well. During the tests, the doctor has you breathe into a spirometer or peak flow meter. These devices measure how much air you are able to blow out of your lungs.
Can you avoid EIB?
You cannot avoid EIB. However, you can help prevent flare-ups. Avoid types of exercise or conditions that trigger symptoms. Work with your doctor to identify these.
Can you exercise with EIB?
Most people who have EIB still are able to exercise. However, you may have to avoid certain types of exercise. Medicine can prevent and manage most symptoms. There also are lifestyle changes you can make.
Why Does Exercise Trigger Bronchospasm?
This requires more rapid breathing. In susceptible folks, this triggers release of chemicals from mast cells (allergy cells) that cause narrowing of the airways in the lungs (bronchospasm). The more rapid the breathing, the more severe the attack might be. Thus, running is more likely to provoke an attack than jogging, and jogging more so than walking.
How long after exercise do you cough?
Symptoms may include wheezing, excessive shortness of breath, chest tightness, or just coughing beginning 5 to 10 minutes after exercise.
What is EIB in exercise?
Exercise-Induced Bronchospasm: Cause and Treatment. In the summer, we are outdoors—and hopefully exercising—more often. About 10% of people who exercise will get exercise-induced bronchospasm (EIB).
Can EIB be caused by exercise?
EIB can occur without exercise, too. Anything that results in breathing in and out rapidly can trigger it, particularly in the asthmatic. This is how asthma came to be mistakenly called an “emotional disease”: a hundred years ago, when their laughing or crying child started wheezing, parents were convinced the asthma attacks were emotional. But we know now that asthma is not an emotional disease.
Can EIB be controlled?
But even with adequate medications, in some patients in certain situations, such as extreme exercise in frigid air, EIB can be difficult to control. Enjoy your summer safely, and hopefully with a lot of exercise—and laughter, too.
Is running in cold air bad for you?
The mechanism is related to cooling and drying of the airways; hence, running in cold, dry air is worse than warm, humid air. The underlying state of the airways might make it worse, too. For example, some asthmatics only have problems with EIB during their pollen allergy seasons, after an upper respiratory infection, or when they have been previously exposed to a cat or other irritant. Irritants also can come into play when exercise is performed on days with poor air quality due to pollution.

What tests are done to check if you have asthma?
The doctor will ask about your symptoms and find out if you have any history of asthma or allergies. Then they will listen to your lungs as you breathe in and out. You may have lung function tests to measure how well your lungs work. These tests may include the following: Spirometry.
What is the term for the tightening of the muscles that line the airways in your lungs?
Bronchospasm is a tightening of the muscles that line the airways (bronchi) in your lungs. When these muscles tighten, your airways narrow. Narrowed airways don’t let as much air come in or go out of your lungs. This limits the amount of oxygen that enters your blood and the amount of carbon dioxide that leaves your blood.
