Debunking Common Myths About COPD
Introduction
COPD, or chronic obstructive pulmonary disease, is an umbrella term for a collection of progressive respiratory conditions that cause breathing difficulties. The most common forms of COPD are chronic bronchitis and emphysema. Shortness of breath and a persistent cough are the most prevalent symptoms, which can make everyday activities challenging over time. In this article, we will debunk some of the most common myths associated with COPD, providing accurate information from two renowned experts in the field: Dr. Neil Schachter, a professor of medicine, and Dr. Shahryar Yadegar, a critical care medicine specialist.

Myth #1: COPD is Rare
Contrary to popular belief, COPD is far from rare. According to the World Health Organization (WHO), COPD caused 3.23 million deaths in 2019, making it the third leading cause of death worldwide. In the United States alone, more than 16 million people are diagnosed with COPD, making it the fourth leading cause of death in the country. However, as Dr. Yadegar points out, millions more people may be undiagnosed. It is crucial for individuals experiencing COPD symptoms to consult with their doctor and undergo a breathing test called “spirometry” for an accurate diagnosis.
Myth #2: Only Smokers Develop COPD
While smoking is the leading cause of COPD, it is not the only risk factor. As Dr. Schachter explains, there are several other factors that contribute to the development of the disease, including air pollution, work-related pollution, infections, and certain forms of asthma. Interestingly, approximately 10-20% of COPD patients have never smoked. Factors such as significant secondhand smoke exposure, genetic predisposition (particularly alpha-1 antitrypsin deficiency), or substantial exposure to air pollution can also increase the risk of developing COPD. Alpha-1 antitrypsin deficiency is a genetic condition that affects the body’s ability to protect against immune attacks.
Myth #3: Only Older Adults Develop COPD
While COPD is more common in older adults, it can affect individuals of any age. In the U.S., between 2007 and 2009, COPD affected 2% of males and 4.1% of females aged 24-44 years, as well as 2% of males and 3% of females aged 18-24 years. Dr. Schachter emphasizes that a significant proportion of individuals diagnosed before the age of 50 have a hereditary form of the disease caused by alpha-1 antitrypsin deficiency.
Myth #4: COPD Only Affects the Lungs
Contrary to popular belief, COPD does not only affect the lungs. Dr. Schachter explains that COPD often coexists with various comorbidities, including heart disease, lung cancer, hypertension, osteoporosis, and diabetes. Some of these comorbidities share risk factors with COPD, such as smoking. Additionally, the association between COPD and systemic inflammation further increases the risk of other conditions.
Myth #5: People with COPD Cannot Exercise
While individuals with COPD may initially struggle with physical exercises, it is highly beneficial for them to engage in appropriate exercise. Exercise helps increase their breathing capacity and improve daily symptoms, as stated by Dr. Yadegar. Pulmonary rehabilitation programs typically offer guided breathing techniques and physical exercises to maximize better patient outcomes. Dr. Schachter confirms that exercise is therapeutic for COPD, reducing the number of exacerbations and improving quality of life. However, it is essential for individuals to consult with their doctor before starting or making changes to their exercise routine.
Myth #6: There are No Treatments for COPD
Thankfully, this myth is untrue. There are numerous therapies and strategies available to improve the course of COPD. These include medications, rehabilitation, diet modifications, and vaccines that protect against respiratory infections that can accelerate the disease’s progression. Inhaled bronchodilators, anticholinergics, corticosteroids, and supplemental oxygen are some of the treatments that can be tailored to each individual’s unique needs. Certain patients may also benefit from alpha-1 antitrypsin augmentation or even lung transplants.
Myth #7: COPD is the Same as Asthma
While both COPD and asthma are classified as obstructive lung diseases, there are significant differences between them. Asthma most commonly begins in childhood and is frequently associated with allergies and inflammation. On the other hand, COPD usually begins in the 60s and is primarily associated with smoking. There is an overlap syndrome between the two, which exhibits features of both diseases. COPD primarily affects the alveoli, causing elasticity loss, while asthma primarily involves chronic airway inflammation. Treatment approaches may vary to provide the best short and long-term outcomes for patients.
Myth #8: Body Weight Does Not Affect COPD
Contrary to popular belief, body weight can significantly impact COPD. Carrying excess body weight can worsen the disability associated with the condition. Conversely, having a body weight below normal levels can indicate emphysema and often indicates a poor prognosis.
Myth #9: Quitting Smoking Has No Benefit for People with COPD
It is never too late to quit smoking, even for individuals with COPD. Smoking accelerates the decline of lung function and promotes exacerbations of COPD symptoms. Quitting smoking is crucial to slow down the disease’s progression and improve overall health.
Myth #10: Shortness of Breath is the Only Symptom of COPD
Shortness of breath is a major symptom of COPD, but it is not the only one. According to Dr. Schachter, cough, excess phlegm production, respiratory infections, and other comorbidity symptoms are often signs of progressing COPD. COPD can also manifest in sleep problems, anxiety, depression, pain, and cognitive decline.
Myth #11: A Healthy Diet Cannot Help with COPD
Contrary to popular belief, a healthy diet can have a positive impact on COPD management. A healthy diet promotes general health and can protect against exacerbations of COPD and its comorbidities. Studies have shown that healthy dietary patterns are associated with a lower prevalence of COPD, while unhealthy dietary patterns do not have the same effect. Higher intake of fruits, dietary fiber, and fish has also been linked to a reduced risk of COPD.
In conclusion, debunking these common myths about COPD helps provide accurate information to the public. While COPD is a prevalent condition, it is essential to understand its causes, symptoms, and available treatments. Lifestyle changes, such as quitting smoking, exercising, and maintaining a healthy diet, can significantly reduce COPD symptoms’ severity and improve overall quality of life.
