Treatment for exercise induced asthma mayo

Exercise-Induced Asthma (EIA) is a sub-type of asthma where prolonged and vigorous exercise triggers asthma attacks. Like allergies, it affects about 75 percent of asthmatics, so its quite common.

The good news is that it can also be prevented. Modern evidence suggests that a better term for this is Exercise-Induced Bronchospasm (EIB).

This is because exercise is just one of many asthma triggers that may induce an asthma flare-up. Its also because you do not have to have asthma for exercise to cause bronchospasm.

What is it? exercise, particularly the allergy aerobic kind, like running, may induce a narrowing of the airways called bronchoconstriction or bronchospasm. It occurs when the bronchial muscles wrapped around the airways spasm and squeeze the airways, thus causing them to become narrow.

This causes airways to become obstructed, thus making you feel symptoms. common symptoms include: Burning, itchy feeling of chest and neck.

Shortness of breath, increased mucus production, coughing. Chest tightness, fatigue during exercise, inability to exercise, avoidance of activity (common in children) *Why does it happen?

.

First, keep in mind that during normal breathing air is inhaled through the nose, which warms it to body temperature and humidifies. While exercising, air is inhaled in rapid, large volumes through the mouth, and may not be adequately warmed and humidified.

Keeping that in mind, experts have theorized that heat and moisture are transferred from airway cells to heat and humidify this air. In susceptible people, this stimulation causes airway cells to release inflammatory mediators, such as histamine and leukotrines. This ultimately leads to bronchospasm and increased mucus production.

Many people with asthma find that this problem is exacerbated when exercising in cold air, such as during the winter time. This is because cold air tends to hold less humidity than warm air.
