When you have asthma, your airways are super sensitive, or "twitchy." They may react to many things. These things are called triggers.
In people who don't have asthma, exposure to such triggers
produces no real response in terms of breathing. But in people at risk for
asthma, the trigger causes your body's immune system to respond to the substance
as though it were a threat to your health. As a result, your immune system
cells set off a series of reactions in an attempt to "fight off" this
threat.
The reactions cause your airways to narrow and tighten. Extra mucus is also produced, which makes it even harder to breathe. The result is an asthma attack. Asthma Attack is a time of increased asthma symptoms.
Asthma is a serious disease, and can kill if it is not treated the right way. But when it is treated the right way, people with asthma can live normal, active lives.
