What is emphysema vs. COPD?
Emphysema and chronic obstructive pulmonary disease (COPD) both refer to a group of long-standing lung conditions that can make breathing difficult. Both of these conditions usually develop in people over 40 years old. Neither COPD or emphysema have a cure, but early action and treatments can improve breathing and overall quality of life.
To understand the relationship between emphysema and COPD, it’s helpful to know the parts of the lungs they affect.
Your lungs are filled with a system of airway tubes. Larger tubes at the top, called bronchi, split into smaller tubes called bronchioles, which carry air inside and out. Tiny air sacs, called alveoli, sit at the ends of the bronchioles. When you inhale, alveoli expand to help transport oxygen into your blood, and when you exhale, they contract to let out carbon dioxide.
What is emphysema?
Emphysema is a subtype of COPD that has to do with the shape of the alveoli and bronchioles. With emphysema, your bronchioles and alveoli are damaged, and have trouble efficiently pushing out all the air you breathe in. The bronchioles expand as you inhale but contract too much when you exhale, so not enough air gets out. This makes breathing difficult.
The alveoli also lose their shape and stretchiness — they can get larger and trap air inside your lungs so that you can’t breathe out fast enough. Damaged alveoli also lose their ability to transport oxygen into your body.
What is COPD?
COPD is an umbrella term for a group of lung conditions that involve breathing difficulty and decreased lung function over time. The two main types of COPD, emphysema and chronic bronchitis, can occur independently or together. Bronchitis refers to inflammation, swelling, and mucus blockage of the bronchi and bronchioles, while emphysema refers to the structural damage of alveoli and bronchioles themselves.
What are symptoms and signs of emphysema vs. COPD?
If you have emphysema, you have COPD — but the two conditions aren’t the same. COPD encompasses more lung conditions than just emphysema.
Symptoms of emphysema
Emphysema can have a variety of symptoms related to breathing difficulty. These symptoms include:
- Cough
- Barrel-shaped chest
- Shortness of breath, especially during exercise or physical activity
- Weight loss
- Wheezing
- Tiredness
- Breathing with pursed lips
- Anxiety and depression
Symptoms of COPD
Other symptoms of COPD come from chronic bronchitis. Chronic bronchitis shares some characteristics with emphysema, but has a few different symptoms:
What are causes of emphysema vs. COPD?
Repeated, long-lasting exposure to cigarette smoke and other harmful chemicals causes both emphysema and COPD.
Causes of emphysema
The most common cause of emphysema is smoking cigarettes. Over time, cigarette smoke destroys the smaller ridges and chambers inside the alveoli that manage oxygen and carbon dioxide exchange. Cigarette smoke also reduces the alveoli’s stretchiness, making it harder to breathe out fully.
Less common causes of emphysema include repeated exposure to secondhand smoke (being close to people who are smoking), breathing in polluted air, and breathing in toxic gases or dust — often in the workplace.
Causes of COPD
Like emphysema, smoking cigarettes is the leading cause of other illnesses under the category of COPD. Chronic bronchitis can also stem from exposure to irritating chemicals and pollutants. If you had a lot of respiratory infections during childhood, you may also be at higher risk of developing COPD.
A rare genetic condition that runs in families makes some people more likely to develop COPD.
QUESTION
COPD (chronic obstructive pulmonary disease) is the same as adult-onset asthma. See AnswerHow to diagnose emphysema vs. COPD
Diagnosing emphysema and COPD are similar processes.
Diagnosing emphysema
A doctor can perform a few examinations specific to emphysema. This could include measuring the size and shape of your chest, a chest X-ray, or CT scan.
Diagnosing COPD
Most of the tests and processes that diagnose emphysema also diagnose COPD. A doctor will likely ask you about your symptoms, personal and family medical history, medications you take, and if you smoke.
Your doctor may also perform some physical tests. These could include:
- Measuring how much air you breathe out with special machines, also known as spirometry
- Examining your fingers and lips for blue discoloration, which indicates low oxygen levels
- Listening to your heart and lungs with a stethoscope

Emphysema and other COPD-related illnesses usually require similar treatments.
Treatments for emphysema
Lung reduction surgery can help address lung swelling and growth as a result of emphysema. Although rare, serious side effects from this type of surgery can include heart attack, infection, and death.
Treatments for COPD
Treatments for multiple types of COPD, including emphysema, can include:
- Vaccination for the flu and pneumonia
- Quitting smoking
- Medicines like bronchodilators
- Inhaled steroids
- Oxygen therapy
- Antibiotics

Can People With COPD Get Better?
Chronic obstructive pulmonary disease (COPD) is not curable in any stage of the disease. With early diagnosis and treatment, disease progression and flare-ups can be controlled.
COPD (Chronic Obstructive Pulmonary Disease)
COPD or chronic obstructive pulmonary disease is a lung condition caused by smoking tobacco, exposure to secondhand smoke, and/or air pollutants. Conditions that accompany COPD include chronic bronchitis, chronic cough, and emphysema.Symptoms of COPD include shortness of breath, wheezing, and chronic cough. Treatment of COPD includes GOLD guidelines, smoking cessation, medications, and surgery. The life expectancy of a person with COPD depends on the stage of the disease.

COPD vs. Emphysema
COPD (chronic obstructive pulmonary disease) is the term doctors and other healthcare professionals use to describe a group of serious, progressive (worsens over time), chronic lung diseases that include emphysema, chronic bronchitis, and sometimes asthma. The number one cause of COPD or emphysema, is smoking, and smoking is the third leading cause of death in the US.
Emphysema
Emphysema is a COPD (chronic obstructive pulmonary disease) that often occurs with other obstructive pulmonary problems and chronic bronchitis. Causes of emphysema include chronic cigarette smoking, exposure to secondhand smoke, air pollution, and in the underdeveloped parts of the world. Symptoms of emphysema include chronic cough, chest discomfort, breathlessness, and wheezing. Treatments include medication and lifestyle changes.
Emphysema, Chronic Bronchitis, and Colds
If you have a COPD such as emphysema, avoiding chronic bronchitis and colds is important to avoid a more severe respiratory infection such as pneumonia. Avoiding cigarette smoking, practice good hygeine, stay away from crowds, and alerting your healthcare provider if you have a sinus infection or cold or cough that becomes worse. Treatment options depend upon the severity of the emphysema, bronchitis, or cold combination.

What are the First Symptoms of Emphysema?
Emphysema is a chronic lung disease that makes breathing difficult. Learn about the early warning signs of emphysema, emphysema symptoms, what causes it, how doctors diagnose it, and your options for treatment.What are the Four Stages of COPD?
COPD (chronic obstructive pulmonary disease) is a group of diseases that cause an inflammatory reaction and irreversible damage in the lungs. The result is obstruction of normal airflow and breathing difficulties. COPD is a lifelong condition with periods of flare ups, and is not curable in any stage of the disease. Emphysema and chronic bronchitis are the most common diseases that make up COPD.
What Is the Life Expectancy of Someone With COPD?
Chronic obstructive pulmonary disease (COPD) is a group of diseases with the chief symptom of breathlessness and cough. COPD is a slowly progressive disease. Depending on the disease severity, the five-year life expectancy for people with chronic obstructive pulmonary disease (COPD) ranges from 40%-70%. That means 40-70 out of 100 people will be alive after five years of diagnosis of COPD.
