About Asthma

Asthma is a condition that affects the airways – the small tubes that carry air in and out of the lungs. If you have asthma your airways are almost always sensitive and inflamed. When you come in to contact with something you are allergic to, or something that irritates your airways (a trigger), your airways will become narrower, making it harder to breathe. The muscles around the walls of your airways tighten. The lining of the airways becomes inflamed and starts to swell and often sticky mucus or phlegm is produced. This will lead to you experiencing asthma symptoms.

The symptoms of asthma, which can range from mild to life threatening, can usually be controlled with a combination of drugs and lifestyle changes.
