Asthma and COPD are among the most common chronic diseases in Canada. In fact, almost 4 million Canadians have a label of asthma, and over 2 million have a label of COPD. People who are diagnosed with asthma or COPD are usually prescribed inhalers (also known as puffers), but rarely recommended pulmonary function testing to confirm the diagnosis.
But did you know that some people on puffers do not actually have asthma or COPD? Studies show that more than 30% of Canadians diagnosed with asthma or COPD do not actually have the condition when formally tested.
