Think of your lungs as balloons. When you’re healthy, those balloons expand and contract as you breathe in and out. But for those with diseased lungs, those balloons deflate and lose their elasticity—limiting the flow of air.
This is known aschronic obstructive pulmonary disease (COPD), a serious condition that makes it difficult to breathe. There are two types of COPD, chronic bronchitis and emphysema, and you can have components of each type to varying degrees. The disease affects the airways as well as the lung, saidRaed Alalawi, MD, a pulmonologist atBanner – University Medical Center Phoenix.
“In the airways, the tubes that carry air within the lung become narrow and limit the movement of air,” Dr. Alalawi said. “In the lung, the part that moves oxygen and carbon dioxide becomes damaged and less efficient at doing its job. The lung can also lose its elasticity, so it becomes harder to get air out of the lung.”
COPD is one of the leading causes of disease-related deaths in the U.S., yet many people, even those recently diagnosed, know very little about it. To better understand COPD, here are five COPD myths and the truths that you should know about.
Myth 1: COPD is a smoker’s disease
COPD affectsmillions of Americans(possibly even more who are undiagnosed). And while it’s true that COPD, like other lung diseases, is more common among those who smoke, it’s not the only thing that causes COPD. Other common causes include:
- Secondhand smokeor other environmental exposures
- Alpha-1 antitrypsin deficiency
- Genetic factors
- Infections
Myth 2: COPD only affects the lungs
While bronchitis and emphysema affect lung tissue, COPD can have effects throughout the body.
“Because COPD restricts the amount of oxygen you get, your heart has to work harder to send oxygenated blood to your body,” Dr. Alalawi said. “This puts a strain on your vascular system and can put you at an increased risk for heart disease.”

Myth 3: All those with COPD are oxygen dependent and if oxygen is started, for any reason, they will become dependent
If you’ve been diagnosed with COPD, you may fear that you’ll be dependent on an oxygen machine for the rest of your life. But this isn’t true.
“Depending on the stage of disease and the reason for starting oxygen it may be a temporary therapy,” Dr. Alalawi said.
Myth 4: There are no treatments for COPD
There are plenty of things you can do these days to manage your symptoms more effectively and even help prevent the disease from getting worse. Things likeprescribed inhalers, supplemental oxygen therapy, regular exercise and an overall healthy lifestyle can help optimize your health. Pulmonary rehabilitation programs that combine education, support and exercise can also help get you back on your feet moving and breathing better.
神话5:慢性阻塞性肺病是incurable-a死亡sentence
Not true, Dr. Alalawi said. “Patients can live a long time with COPD, especially now that we have so many treatment therapies and options when it comes to managing the disease.”
While COPD is a progressive disease, if you work closely with your healthcare team, follow your treatment plan, exercise regularly and eat healthy, you’ll find that COPD isn’t a death sentence.
