Chronic obstructive pulmonary disease (COPD) is a common lung disease. Having COPD makes it hard to breathe.
There are two main forms of COPD:
Most people with COPD have a combination of both conditions.
COPD; Chronic obstructive airways disease; Chronic obstructive lung disease; Chronic bronchitis; Emphysema; Bronchitis - chronic
Smoking is the main cause of COPD. The more a person smokes, the more likely that person will develop COPD. But some people smoke for years and never get COPD.
In rare cases, nonsmokers who lack a protein called alpha-1 antitrypsin can develop emphysema.
Other risk factors for COPD are:
Symptoms may include any of the following:
Because the symptoms develop slowly, some people may not know that they have COPD.
The best test for COPD is a lung function test called spirometry. This involves blowing out as hard as possible into a small machine that tests lung capacity. The results can be checked right away.
Using a stethoscope to listen to the lungs can also be helpful. But sometimes, the lungs sound normal, even when a person has COPD.
Sometimes, a blood test called arterial blood gas may be done to measure the amounts of oxygen and carbon dioxide in the blood.
There is no cure for COPD. But there are many things you can do to relieve symptoms and keep the disease from getting worse.
If you smoke, now is the time to quit. This is the best way to slow lung damage.
Medicines used to treat COPD include:
In severe cases or during flare-ups, you may need to receive:
Your health care provider may prescribe antibiotics during symptom flare-ups, because an infection can make COPD worse.
You may need oxygen therapy at home if you have a low level of oxygen in your blood.
Pulmonary rehabilitation does not cure COPD. But it can teach you to breathe in a different way so you can stay active and feel better.
LIVING WITH COPD
You can do things every day to keep COPD from getting worse, protect your lungs, and stay healthy.
Walk to build up strength:
Things you can do to make it easier for yourself around the home include:
Eat healthy foods, including fish, poultry, and lean meat, as well as fruits and vegetables. If it is hard to keep your weight up, talk to a provider or dietitian about eating foods with more calories.
Surgery may be used to treat COPD. Only a few patients benefit from these surgical treatments:
You can ease the stress of illness by joining a support group. Sharing with others who have common experiences and problems can help you not feel alone.
COPD is a long-term (chronic) illness. The disease will get worse more quickly if you do not stop smoking.
If you have severe COPD, you will be short of breath with most activities. You may be admitted to the hospital more often.
Talk with your provider about breathing machines and end-of-life care as the disease progresses.
With COPD, you may have other health problems such as:
Go to the emergency room or call the local emergency number (such as 911) if you have a rapid increase in shortness of breath.
Not smoking prevents most COPD. Ask your provider about quit-smoking programs. Medicines are also available to help you stop smoking.
