Lung Diseases

Listen to your lungs

Are you huffing and puffing, hacking or crackling? Those lungs might be giving you a noisy wake-up call. Lung disease affects millions of Canadians. And our asthma rates are among the highest in the world.

Take our two easy online tests below to figure out what your lungs could be telling you. Don’t ignore the symptoms that might be right under your nose.


Asthma is a chronic (life-long) condition that makes it harder to breathe. This is because the airways in your lungs are more sensitive, and get filled with mucus or tighten up when you’re around triggers, making it harder for air to pass through.

While asthma can’t be cured, with proper treatment, people with asthma can lead normal, healthy, active lives.

Take the Asthma Control Check

Wheezing when breathing?

Many people with asthma miss work, skip sports or wake up during the night because of wheezing, coughing, chest tightness, or shortness of breath. But with proper care and monitoring, you can reach asthma control. Below you will find tools and advice on how to regularly check up on your asthma, and what to do about it if it does get out of control. To ensure that you are getting the proper treatment, you should continuously keep an eye on the disease and communicate with your doctor.

If you answer YES to any of these questions, speak to your healthcare provider about the right medications for you to take control of your asthma.

  1. Do you have to use your reliever inhaler more than twice per week?
  2. Do you have asthma symptoms more than twice per week (cough, wheeze, difficulty breathing)?
  3. Do you ever have difficulty exercising or playing sports because of asthma?
  4. Do you wake up even one night per week because of asthma (cough, wheeze, difficulty breathing) and if so, are the symptoms mild?
  5. Have you missed school or work days in the last month because of asthma?
  6. Do you ever have asthma flare-ups (worsening of cough, wheeze, difficulty breathing)?
