current estimates suggest that copd affects two million canadians, with another million potentially undiagnosed and untreated.
according to the canadian institute for health information, copd accounts for 76,000 annual hospitalizations and is surpassed only by childbirth.
the two main forms of copd are emphysema and chronic bronchitis that usually occur together.
in emphysema, the small air sacs of the lungs, called alveoli, are damaged and can’t pass enough oxygen into the bloodstream. chronic bronchitis is inflammation of the lining of the tubes that bring air into the lungs, reducing airflow and making extra mucus.
smoker stigma and shame is hurting copd progress
dr. pierre landry, respirologist at dartmouth general hospital in halifax, says patients often come to him in fear.
“a lot of patients are afraid of running out of oxygen. you know, they’re afraid of suffering. they’re afraid of the symptoms and lung cancer,” he says, noting copd increases the risk of lung cancer and the need for lung transplant.
“some people say, ‘i saw my mom on oxygen and she really suffered,'” dr. landry explains. his role is helping people understand the complex disease process and finding treatment options that work best. part of his job also involves forming long-term relationships with people that become end-of-life moments.
while cardiac diseases, like heart disease and stroke, are more widely recognized and supported by research dollars, copd has been “swept under the rug” because of its link to cigarette smoking and “normalizing” that the disease is caused by long-term cigarette smoking.
dr. landry emphasizes the treatment landscape has evolved very slowly compared to cardiac drugs, but there’s new hope with effective biologic medications that help manage symptoms.
