Asthma

Asthma is a chronic condition that is characterised by tightening and inflammation of the airways. In most cases, its underlying cause is unknown but it may be triggered by substances you are allergic to, or other triggers such as stress or depression.

In this section, you can learn about the types, causes and symptoms of asthma and watch an animation of what is happening to your body. You can also find out about what to do if you've just been diagnosed, as well as what you can do in the longer term and how medicines can help.
