What is Asthma?

Asthma is a chronic illness that can range from mild to severe. This means there is no cure, it will always affect your lungs to a certain extent. Asthma affects 8.4% of Canadians. Uncontrolled asthma is very common, however, proper medication and good self-management skills can help most people gain control of their asthma.

When someone has asthma, factors in the environment and physical processes inside the body can activate your immune system. Normally, the body’s immune system protects us from harmful bacteria, viruses, allergens and toxins. But in asthma, the immune system reacts to things that do not necessarily pose a threat, such as allergens (e.g. dust mites in the air you breathe, pet dander, pollens, etc.). Protective cells release chemicals that cause swelling in the airways.

What are the symptoms of asthma?

Asthma can range from very mild to more severe. Here are some of the common symptoms of asthma that are caused by airway inflammation and muscle spasm:
