What is Asthma?


Asthma is a chronic inflammatory disease that can cause airways to tighten, swell and produce excess mucus.

Symptoms include wheezing (a whistling sound when you breathe), coughing, chest tightness and difficulty breathing, especially at night and in the early morning.

You may have all or just a few of these symptoms and they may vary from one episode to the next.

Some people with asthma have extended symptom-free periods, while others experience symptoms daily.

In addition, some people with asthma only have symptoms during exercise or when they are exposed to allergens or viral respiratory tract infections.

It is important to recognize and treat even mild asthma symptoms to help you prevent severe episodes and keep asthma under control.

Asthma has no cure, but many treatments are available to minimize symptoms and help those with asthma lead normal, active lives.
