At first, COPD may cause no symptoms or only mild symptoms. As the disease gets worse, symptoms usually become more severe. Common signs and symptoms of COPD include:
If you have COPD, you also may have colds or the flu (influenza) often.
Not everyone who has the symptoms above has COPD. Likewise, not everyone who has COPD has these symptoms. Some of the symptoms of COPD are similar to the symptoms of other diseases and conditions. Your doctor can find out whether you have COPD.
If your symptoms are mild, you may not notice them, or you may adjust your lifestyle to make breathing easier. For example, you may take the elevator instead of the stairs.
Over time, symptoms may become severe enough to see a doctor. For example, you may get short of breath during physical exertion.
The severity of your symptoms will depend on how much lung damage you have. If you keep smoking, the damage will occur faster than if you stop smoking.
Severe COPD can cause other symptoms, such as swelling in your ankles, feet, or legs; weight loss; and lower muscle endurance.
Some severe symptoms may require treatment in a hospital. You—with the help of family members or friends, if you're unable—should seek emergency care if:
The NHLBI "Grand Opportunity" Exome Sequencing Project
If you have COPD or think you might be at risk, you can take steps to make breathing easier and live a longer and more active life. Get a simple breathing test and talk with your doctor or health care provider about treatment options.
The NHLBI developed the national COPD Learn More Breathe Better® campaign to increase awareness of COPD. The campaign aims to help people with COPD and those at risk get diagnosed early, understand their treatment options, and live better with the disease.

Clinical trials are research studies that explore whether a medical strategy, treatment, or device is safe and effective for humans. To find clinical trials that are currently underway for COPD, visit www.clinicaltrials.gov.

COPD awareness continues to rise, new NIH survey finds
Awareness of COPD (chronic obstructive pulmonary disease), the nation’s third leading killer, continues to rise in the United States, according to the results of a Web-based survey released today by the National Heart, Lung, and Blood Institute (NHLBI) of the National Institutes of Health.
More than 10,000 volunteers are taking part in an NHLBI-sponsored clinical study to learn more about the role of genetics in COPD. NHLBI grantee Dr. Edwin Silverman discusses this research and the vital role that volunteers play in advancing medical knowledge in this video.
The NHLBI updates Health Topics articles on a biennial cycle based on a thorough review of research findings and new literature. The articles also are updated as needed if important new research is published. The date on each Health Topics article reflects when the content was originally posted or last revised.
