Asthma is a condition that affects the lungs. The airways (the tubes that carry air in and out of the body) get inflamed and produce a thick liquid called mucus. This makes the airways tight and narrow.
Asthma can cause:
Symptoms can be made worse by triggers such as smoke, allergies, viruses or cold air.
Asthma can have other symptoms too, so it is not always easy to diagnose.
When the symptoms get worse, it is known as an asthma attack and this can be very serious. If you have asthma, you should make sure you know what to do if you have an asthma attack.
