Living with Asthma

Asthma is a chronic respiratory disease, characterized by narrowing of the airways and excess mucus production. People with asthma typically suffer from chest tightness/pain, shortness of breath, and episodes of coughing and wheezing.

Asthma Worldwide

While asthma is not curable, proper management and awareness allow most people to live a normal life. Unfortunately, many people do not perceive asthma as serious. Proper diagnosis, treatment, monitoring, and planning of your or your loved one’s asthma, can help protect them during an asthma attack.

The Anatomy of Asthma

Asthma severity and exacerbations vary between each person. For some people, asthma symptoms occur randomly, or only during periods of exertion/exercise or when exposed to certain triggers. For other people, asthma symptoms may present all the time. If asthma is poorly controlled or not taken seriously, this may mean that people are not able to enjoy the activities they love, such as hiking, playing sports, or gardening. In Canada, over 75% of people with asthma are reported as having poorly controlled asthma, many mistakenly believing their asthma is under control.3 Poor asthma control can lead to increased risk of asthma attacks and adverse effects.4

Asthma Deaths

It is estimated that 80% of all asthma related deaths could have been prevented with proper education and management.
