Chronic Obstructive Pulmonary Disease (COPD)
This is a lung disease that makes it hard to breathe. In people with COPD, the airways (the branching tubes that carry air within the lungs) become narrow and can be clogged with mucus. The air sacs can also get damaged. This makes people feel out of breath and tired.
COPD can be a serious illness. It cannot be cured and can get worse over time. But there are treatments that can help.
There are 2 types of COPD: "chronic bronchitis" and "emphysema."
What causes COPD?
The most common cause is smoking. Smoke can damage the lungs permanently and cause COPD. People can also get COPD from breathing in toxic fumes or gases. In rare cases, COPD is caused by a genetic problem. A blood test can check for this.
What are the symptoms of COPD?
At first, COPD often causes no symptoms. As it gets worse, it can make you:
- Feel short of breath, especially when you are moving around
- Wheeze (make a whistling or squeaking noise as you breathe)
- Cough and spit up sputum (mucus)
People who have COPD are also at increased risk for:
- Infections, such as pneumonia
- Lung cancer
- Heart patients
Is there a test for COPD?
Yes. You might get a test called "spirometry" to check for COPD. You take a deep breath, and then blow out as fast and hard as you can into a tube. A machine connected to the tube measures how much air you can blow out of your lungs and how fast.
If the results of your spirometry are not normal, you will take medicine in an inhaler to see if your breathing gets better. Then, after a few minutes, you will repeat the spirometry. This helps the doctor or nurse find out if your problem is caused by COPD or another lung problem, such as asthma. People with asthma usually get normal results after they use an inhaler. People with COPD often do not.
Your doctor might order other tests, too. These can check to see if other problems besides COPD might be causing your symptoms. They can also look for some of the problems COPD can lead to.
You might get a:
Blood test – This can check for a genetic problem called "antitrypsin deficiency" that can cause early COPD in people who smoke.
Chest X-ray
Electrocardiogram ("ECG") – This measures the electrical activity in the heart.
Low-dose CT scan – This is an imaging test used to screen for lung cancer. (Imaging tests create pictures of the inside of the body.) Your doctor or nurse might suggest lung cancer screening depending on your age, how much you have smoked in the past, and whether you still smoke
How is COPD treated?
Medicines
There are many medicines to treat COPD. Most people use inhalers to help open up their airways or decrease swelling in their airways. Often, people need more than 1 inhaler at a time. You might need a steroid medicine in a pill for a COPD "flare." This is when symptoms suddenly, but temporarily, get worse.Oxygen
If the disease gets worse, you might need to use oxygen. Your doctor or nurse can test your blood oxygen to see if you need this.Pulmonary Rehabilitation ("pulmonary rehab")
You learn exercises and ways to breathe that can help ease symptoms. Even if you don't do a pulmonary rehab program, staying active can help your breathing.What can I do on my own?
Quit smoking, if you smoke
This is the most important thing you can do for your health. This is true no matter how long you have smoked or how much you smoke. Your doctor or nurse can help you quit.Avoid triggers
If things like fumes, pollution, or dust make your breathing worse, try to avoid them.Low your risk of infection
Certain infections can be very hard on your lungs and can cause COPD symptoms to flare up. You can lower your risk by getting certain vaccines. These include vaccines to protect against the flu, pneumonia, and COVID-19. Also, wash your hands often and stay away from people who are sick.Make a healthy lifestyle changes
Eating a healthy diet can help improve your health. You can also improve your health by following your pulmonary rehab plan if you have one, or finding other ways to move your body.When should I attend emergency department?
- Have trouble breathing, even when resting
- Cough up blood
- Call your doctor for advice if you:
- Symptoms of a heart attack usually include feeling pressure, discomfort, or pain in the chest, arms, back, or jaw.
- Some people have trouble breathing, sweat, feel dizzy, or pass out.
- Symptoms usually get worse with activity, like walking up stairs.
- If you are used to having symptoms only with activity, call for help if you start having them when you are not active.
Call your doctor for advice if you:
- Have a fever of 100.4°F (38°C) or higher, or chills
- Feel weak or more short of breath than usual when doing your normal activities
- Have new or worsening cough, wheezing, sputum, or shortness of breath
Frequently Asked Questions
What is COPD?
COPD (Chronic Obstructive Pulmonary Disease) is a long-term lung disease that causes airflow blockage, making it difficult to breathe. It includes conditions such as chronic bronchitis and emphysema.
What are the common symptoms of COPD?
Common symptoms include persistent cough, shortness of breath, wheezing, chest tightness, excessive mucus production, and frequent respiratory infections. Symptoms usually worsen over time if left untreated.
What causes COPD?
The most common cause of COPD is long-term smoking. Other causes include exposure to secondhand smoke, air pollution, dust, chemical fumes, and, in some cases, a genetic condition called alpha-1 antitrypsin deficiency.
How is COPD diagnosed?
COPD is diagnosed using a detailed medical history, physical examination, and Spirometry (Pulmonary Function Test) to measure lung function. Your doctor may also recommend a chest X-ray or CT scan if needed.
