Get the Facts About COPD

Most people who are at risk for getting COPD (chronic obstructive pulmonary disease) have never even heard of it and, in many cases, don’t even realize that the condition has a name. COPD is a lung disease that consists of shortness of breath, chronic coughing or wheezing just to name of few. Two of the most common types of COPD are emphysema and chronic bronchitis. But, as mentioned, many people don’t know the facts about COPD. Here are things you need to know about this disease.

Am I Risk? – Get the Facts About COPD

Some of the things that put you at risk for COPD include:

  • Smoking: COPD most often occurs in people age 40 and over with a history of smoking (either current or former smokers), although as many as one out of four people with COPD never smoked. Smoking is the most common cause of COPD—it accounts for as many as eight out of ten COPD-related deaths.
  • Environmental exposure: COPD can also occur in people who have had long-term exposure to things that can irritate your lungs, like certain chemicals, dust, or fumes in the workplace. Heavy or long-term exposure to secondhand smoke or other air pollutants may also contribute to COPD.
  • Genetic factors: In some people, COPD is caused by a genetic condition known as alpha-1 antitrypsin, or AAT, deficiency. While very few people know they have AAT deficiency, it is estimated that close to 100,000 Americans have it. People with AAT deficiency can get COPD even if they have never smoked or had long-term exposure to harmful pollutants.

How Does COPD Affect Breathing? – Get the Facts About COPD

The “airways” are the tubes that carry air in and out of the lungs through the nose and mouth. Healthy airways and air sacs in the lungs are elastic—they try to bounce back to their original shape after being stretched or filled with air, just the way a new rubber band or balloon does. This elastic quality helps retain the normal structure of the lung and helps to move the air quickly in and out.

In people with COPD, the air sacs no longer bounce back to their original shape. The airways can also become swollen or thicker than normal, and mucus production might increase. The floppy airways are blocked, or obstructed, making it even harder to get air out of the lungs.

Symptoms

Many people with COPD avoid activities that they used to enjoy because they become short of breath more easily.

Symptoms of COPD include:

  • Constant coughing, sometimes called “smoker’s cough”
  • Shortness of breath while doing activities you used to be able to do
  • Excess sputum production
  • Feeling like you can’t breathe
  • Not being able to take a deep breath
  • Wheezing
  • A combination of all of the above

When COPD is severe, shortness of breath and other symptoms can get in the way of doing even the most basic tasks, such as doing light housework, taking a walk, even bathing and getting dressed.

COPD develops slowly, and can worsen over time, so be sure to report any symptoms you might have to your doctor or health care provider as soon as possible, no matter how mild they may seem.

Getting Tested – Get the Facts About COPD

Everyone at risk for COPD who has a persistent cough, sputum production, or shortness of breath, should be tested for the disease. The test for COPD is called spirometry.

Spirometry can detect COPD before symptoms become severe. It is a simple, non-invasive breathing test that measures the amount of air a person can blow out of the lungs (volume) and how fast he or she can blow it out (flow). The test helps detect COPD and its severity and can also find out whether other conditions, such as asthma or heart failure, are causing the symptoms. Based on this test, your doctor or health care provider can tell if you have COPD, and if so, how severe it is. The spirometry reading can help them to determine the best course of treatment.

Spirometry

Spirometry is one of the best and most common lung function tests. The test is done with a spirometer, a machine that measures how well your lungs function, records the results, and displays them on a graph. You will be asked to take a deep breath, then blow out as hard and as fast as you can using a mouthpiece connected to the machine with tubing. The spirometer then measures the total amount exhaled, called the forced vital capacity or FVC, and how much you exhaled in the first second, called the forced expiratory volume in 1 second or FEV1. Your doctor or health care provider will read the results to assess how well your lungs are working and whether you have COPD.

 Other Tests

Your doctor may recommend other tests, such as:

  • A chest x-ray or chest CT scan. These tests create pictures of the structures inside your chest, such as your heart, lungs, and blood vessels. The pictures can show signs of COPD. They also may show whether another condition, such as heart failure, is causing your symptoms.
  • An arterial blood gas test. This blood test measures the oxygen level in your blood using a sample of blood taken from an artery. The results from this test can show how severe your COPD is and whether you need oxygen therapy.

Taking Action – Get the Facts About COPD

There are many things people at risk for COPD can do:

Quit Smoking

If you smoke, the best thing you can do to prevent more damage to your lungs is to quit. To help you quit, there are many online resources and several new aids available from your doctor or health care provider. The National Cancer Institute has information on smoking cessation. Visit SmokeFree.gov, the American Lung Association, or call 1-800-QUIT NOW for more information.

Avoid Exposure to Pollutants

Try to stay away from other things that could irritate your lungs, like dust and strong fumes. Stay indoors when the outside air quality is poor. You should also stay away from places where there might be cigarette smoke.

Visit Your Doctor or Health Care Provider on a Regular Basis

See your doctor or health care provider regularly even if you are feeling fine. Make a list of your breathing symptoms and think about any activities that you can no longer do because of shortness of breath. Be sure to bring a list of all the medicines you are taking to each office visit.

Take Precautions Against the Seasonal Flu

Do your best to avoid crowds during flu season. In addition to avoiding people with the flu, remembering to wash and sanitize your hands can be one of the best ways to guard against getting sick. It is also a good idea to get a flu shot every year, since the flu can cause serious problems for people with COPD. You should also ask your doctor or health care provider about the pneumonia vaccine. Visit the Centers for Disease Control and Prevention for more information about vaccinations in general and for people with high risk of developing flu-related complications.
