What is Asthma?
Asthma is a long-term lung disease with swelling and narrowing of the airway. Asthma cannot be cured, but can be controlled with proper care.
- The airways are tubes that carry air into and out of your lungs.
- People who have asthma have inflamed and sensitive airways.
- Inflamed airways tend to be very sensitive, and more reactive.
- When the airways react, the muscles around them tighten.
- The swelling gets worse too, making the airways even more narrow.
- Cells in the airways might make more mucus than usual.
- Mucus is a sticky, thick liquid that can further narrow the airways.
- The narrowing of the airways causes less air to flow into the lungs.
Asthma symptoms are results of this chain reaction. Symptoms can happen each time the airways are inflamed.
