Today’s edition of Medical Myths centers on misconceptions about chronic obstructive pulmonary disease. We cover myths about exercise, body weight, treatments, and more.
In our Medical Myths series, we approach medical misinformation head on. Using expert insight and peer reviewed research to wrestle fact from fiction, MNT brings clarity to the myth riddled world of health journalism.
Over the long haul, even ordinary exercises, for example, getting dressed, can become testing.
COPD is an umbrella term for a collection of progressive respiratory conditions, all of which cause breathing difficulties.
Two of the most common forms of COPD are chronic bronchitis and emphysema.
The most prevalent symptoms of are shortness of breath and a cough. Over time, even everyday activities, such as getting dressed, can become challenging.
In this article, we cover some of the most common myths associated with COPD. To ensure we provide accurate information, we have recruited two experts.
Dr. Neil Schachter is a professor of medicine — pulmonary, critical care, environmental medicine, and public health — at the Icahn School of Medicine at Mount Sinai in New York. He is also medical director of pulmonary rehabilitation at the Mount Sinai Health System.
Over the long run, even regular exercises, for example, getting dressed, can become testing.
Dr. Shahryar Yadegar is a critical care medicine specialist, pulmonologist, and medical director of the ICU at Providence Cedars-Sinai Tarzana Medical Center, CA.
He is likewise clinical overseer of pneumonic restoration at the Mount Sinai Health System.
1. COPD is rare
According to the World Health Organization (WHO), COPD caused 3.23 millionTrusted Source deaths in 2019, making it the third leading cause of death worldwide.
In excess of 16 million Americans are analyzed.”
Dr. Schachter explained that in the United States, COPD “is the fourth leading causeTrusted Source of death. More than 16 million Americans are diagnosed.”
Additionally, as Dr. Yadegar told Medical News Today, “millionsTrusted Source more people may be undiagnosed.”
The American Lung Association (ALA) recommends that anyone who is “experiencing COPD symptoms — chronic cough, shortness of breath, frequent respiratory infections, significant mucus production (also called phlegm or sputum), and/or wheezing — speak with [a] doctor about obtaining a breathing test called ‘spirometry,’ which can help diagnose COPD.”
2. Only smokers develop
It is true that smoking tobacco is the leading cause of , but as Dr. Schachter told MNT, “There are many other risk factors that contribute to the development of the disease, including air pollution, work-related pollution, infection, and some forms of asthma.”
Extending this further, Dr. Yadegar told us:
“Approximately 10–20% of patients never smoked. Some of these never-smokers include significant secondhand smoke exposure; genetic predisposition, primarily through alpha-1 antitrypsin deficiency; or substantial exposure to air pollution.”
Alpha-1 antitrypsin is an enzyme that protects the body from an immune attack. Some people have a mutation in the gene that codes for this enzyme; this causes alpha-1 antitrypsin deficiency.
Deficiency of alpha-1 antitrypsin increases the risk of developing COPD and other conditions that affect a range of bodily systems.
3. Only older adults develop COPD
COPD is certainly more common in older adults than in younger people, but younger people are not immune to the condition.
For instance, in the U.S., between 2007 and 2009, COPD affected 2%Trusted Source of males and 4.1% of females aged 24–44 years. Similarly, the condition affected 2% of males and 3% of females aged 18–24 years.
Dr. Schachter told us that a “significant proportion of those individuals diagnosed before the age of 50” have a hereditary form of the disease that causes a deficiency of alpha-1 antitrypsin.
4. only affects the lungs
“False,” said Dr. Schachter. “COPD coexists with many comorbidities, including heart disease, lung cancer, hypertension, osteoporosis, and diabetes. The association may be due to common causative factors, as well as ‘systemic inflammation.’”
In other words, some of these conditions share risk factors, which makes them more likely to occur with COPD. For instance, smoking is a risk factor for both and heart disease.
At the same time, health experts associate COPD with systemic inflammation, which can also independently increase the risk of other conditions.
5. People with cannot exercise
According to Dr. Yadegar, “Without proper guidance, patients with COPD may have difficulty completing physical exercises.”
However, he also explained that doctors recommend people with COPD do exercise, as it can help “increase their breathing capacity and improve their daily symptoms.”
“Pulmonary rehabilitation programs typically offer guided breathing techniques in conjunction with physical exercise in order to maximize better patient outcomes,” he continued.
“You may feel like it isn’t protected or even conceivable to work out, yet the perfect sum and kind of activity has many advantages. Make certain to ask your PCP before you start or make changes to your activity schedule.”
In a nutshell, Dr. Schachter told us that “exercise is therapeutic for , reducing the number of exacerbations and improving quality of life.”
“While clinical side effects might cover between the two illnesses,” he proceeded, “medicines shift to best assistance patients in the short and long haul.”
The ALA notes:
“You might feel like it is not safe or even possible to exercise, but the right amount and type of exercise has many benefits. Be sure to ask your doctor before you start or make changes to your exercise routine.”
6. There are no treatments
This, thankfully, is a myth. “There are numerous therapies and strategies that improve the course of the disease,” Dr. Schachter told MNT, “including medications, rehabilitation, diet, and vaccines that protect against respiratory infections that accelerate the course of the disease.”
“Certain patients may likewise profit from alpha-1 antitrypsin expansion or even lung transfers,” he added.
Dr. Yadegar said, “With a spectrum of presentations, patients may benefit from inhaled bronchodilators, anticholinergics, corticosteroids, and supplemental oxygen.” These, he said, can be tailored uniquely to each person.
“Certain patients may also benefit from alpha-1 antitrypsin augmentation or even lung transplants,” he added.
7. COPD is the same as asthma
“While both diseases are considered obstructive lung diseases, there are several differences between and asthma,” Dr. Yadegar explained.
“Asthma most commonly begins in childhood, where it is frequently associated with allergies and problems of inflammation. COPD usually begins in the 60s and is associated with smoking. There is, however, an overlap syndrome, which has features of both.”
– Dr. Neil Schachter
Dr. Yadegar dove into the details: “COPD is a disease of the alveoli, mostly […] a result of elasticity loss induced primarily by smoking. Asthma is a disease of the airways, primarily […] a result of chronic airway inflammation.”
When managing COPD, it very well may be difficult to sift through the commotion and explore your inbox.
“While clinical symptoms may overlap between the two diseases,” he continued, “treatments vary in order to best help patients in the short and long term.”

8. Body weight does not affect COPD
On the other hand, in case individuals have a body weight that is underneath moderate, it tends to be “an indication of emphysema and furthermore shows a helpless anticipation.”
Then again, in case individuals have a body weight that is underneath moderate, it very well may be “an indication of emphysema and furthermore demonstrates a helpless anticipation.”
This is not true. Dr. Schachter told us that carrying excess body weight can increase the disability associated with COPD.
Conversely, if people have a body weight that is below moderate, it can be “a sign of emphysema and also indicates a poor prognosis.”
9. If you have COPD, there is no point quitting smoking
This is another myth. As Dr. Schachter told MNT, “It is never too late to quit.”
He explained that “smoking accelerates the loss of lung function that accompanies .” He also said that smoking tobacco can promote exacerbations of the symptoms.
10. Shortness of breath is the only symptom
“Shortness of breath is a major presenting symptom but hardly the only one,” according to Dr. Schachter.
Genuinely, a sound eating routine can fundamentally affect people living with COPD.
“Cough, excess phlegm production, respiratory infections, and all the symptoms of the comorbidities are often signs of progressing COPD.”
Other symptoms can include sleep problems, anxiety, depression, pain, and cognitive decline.
As a matter of fact, a healthy diet can make a difference for people living with COPD. Dr. Schachter told MNT that a healthy diet promotes “general health and can protect against exacerbations of itself and its comorbidities.”
Truly, a sound eating regimen can significantly impact individuals living with COPD.
Without a doubt, a sound eating routine can essentially affect people living with COPD.
For example, a 2020 meta-analysis of eight observational studies investigated the role of diet in COPD. The authors conclude that “healthy dietary patterns are associated with a lower prevalence of COPD, while unhealthy dietary patterns are not.”
Indeed, a sound eating regimen can significantly impact individuals living with COPD.
Similarly, the data generated in another reviewTrusted Source suggest that “a higher intake of fruits, probably dietary fiber, and fish reduce the risk of COPD.”
To be sure, a sound eating routine can fundamentally affect people living with COPD.
In summary, although there is no cure for COPD, treatments are available, and lifestyle changes can reduce symptom severity. For more information on the causes, diagnosis, symptoms, and treatment of COPD, click here.
