Chronic lung disease isn’t just one single type of respiratory disease. Think of it more as an umbrella term covering an assortment of conditions that prevent your lungs from working the way they should.
Common types of chronic lung disease include:
Chronic obstructive pulmonary disease (COPD): Smoking causes about 80% of deaths from COPD, according to the U.S. Centers for Disease Control and Prevention (CDC).
Emphysema: This form of COPD damages the walls of your lungs, making it more difficult for you to move air in and out of them.
Chronic bronchitis: This condition also is a type of COPD. But in this case, the damage is to tiny hairs (cilia) that work to keep your airways clean.
Chronic lung disease can be traced to many causes, but smoking tops the list. Others include environmental factors (such as air pollution, asbestos and second-hand smoke), infections and even genetics.
Smoking and chronic lung disease
Breathing in chemicals certainly sounds bad for your lungs, right? Well, consider this: Lighting up a cigarette and taking a puff releases thousands of chemicals, many of which carry a toxic designation. Chemicals in cigarettes can irritate and damage your airways and lungs, says Dr. Choi. Research shows that smoking just a few cigarettes a day can cause immense harm over time. “It’s a misconception to think that smoking very lightly, just one or two cigarettes a day, could somehow be a safe practice,” states Dr. Choi. “There’s a body of evidence showing that it is not.”
Signs of lung damage from smoking
The cumulative effect of smoking can lead to noticeable changes in your breathing and lung health, including:
-Shortness of breath. You know that out-of-breath feeling that comes during exercise? Lung damage caused by smoking can make that a regular occurrence even if you’re not exerting yourself.
-A chronic cough. Coughing is your body’s natural response to try to compensate for gunk that builds up in your airways from smoking.
-Increased mucus production. Mucus is a defense mechanism your body uses to deal with airway irritants like cigarette smoke. It can also lead to a wet cough often called “smoker’s cough.”
– Wheezing. Airway inflammation caused by smoking can lead to noisy breathing.
Can you stop chronic lung disease?
If you smoke and are worried about getting chronic lung disease, here’s your best solution: Quit smoking. It’s really that simple. In fact, research shows that heavy smokers who kick the habit have a lower risk of lung disease than current light smokers. “Quitting smoking at any point in life can lower a person’s chance of developing chronic lung disease,” emphasizes Dr. Choi. “It is never too late to quit.” Within three days of quitting smoking, breathing typically becomes easier. Chronic coughing may ease up after a few months, too, as the cilia (small hairs) in your airways gradually begin to regrow. (Learn more health benefits that come when you stop smoking.) Talk to a healthcare provider about your options for a smoking cessation program.
Does quitting smoking reverse damage?
Unfortunately, the answer is no. Years or decades of abusing your lungs can’t just be erased. Some damage will be lasting. But that doesn’t mean chronic lung disease can’t be managed for better quality of life, says Dr. Choi. Various treatment options can help your lungs. Lifestyle changes, such as quitting smoking, can prevent additional damage and allow for some recovery.
