Chronic obstructive pulmonary disease (COPD) is a common lung disease. Having COPD makes it hard to breathe.

There are two main forms of COPD:

• Chronic bronchitis, which involves a long-term cough with mucus
• Emphysema, which involves damage to the lungs over time

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.

If a person has a rare condition in which they lack a protein called alpha-1 antitrypsin, they can develop emphysema even without smoking.

Other risk factors for COPD are:

• Exposure to certain gases or fumes in the workplace
• Exposure to heavy amounts of secondhand smoke and pollution
• Frequent use of a cooking fire without proper ventilation

Symptoms may include any of the following:

• Cough, with or without mucus
• Fatigue
• Frequent respiratory infections
• Shortness of breath (dyspnea) that gets worse with mild activity
• Trouble catching one's breath
• Wheezing

Because the symptoms develop slowly, many people may not know that they have COPD.

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:

• Quick-relief medicines to help open the airways
• Control medicines to reduce lung inflammation
• Anti-inflammatory medicines to reduce swelling in the airways
• Certain long-term antibiotics

In severe cases or during flare-ups, you may need to receive:

• Steroids by mouth or through a vein (intravenously)
• Bronchodilators through a nebulizer
• Oxygen therapy
• Assistance from a machine (ventilator) to help breathing by using a mask or through the use of an endotracheal tube

Your 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 more about the disease, train you to breathe in a different way so you can stay active and feel better, and keep you functioning at the highest level possible.

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:

• Ask your provider or respiratory therapist how far to walk.
• Slowly increase how far you walk.
• Avoid talking if you get short of breath when you walk.
• Use pursed lip breathing when you breathe out, to empty your lungs before the next breath.

Things you can do to make it easier for yourself around the home include:

• Avoid very cold air or very hot weather
• Make sure no one smokes in your home
• Reduce air pollution by not using the fireplace and getting rid of other irritants
• Manage stress and your mood
• Use oxygen if prescribed for you

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, by eating small frequent meals.

Surgery or other interventions may be used to treat COPD. Only a few people benefit from these surgical treatments:

• One-way valves can be inserted with a bronchoscopy to help deflate parts of the lung that are hyperinflated (overinflated) in select people.
• Surgery to remove parts of the diseased lung, which can help less-diseased parts work better in some people with emphysema (lung volume reduction surgery).
• Lung transplant for a small number of very severe cases.

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:

• Irregular heartbeat (arrhythmia)
• Need for breathing machine support with a mask (non-invasive ventilation) and oxygen therapy
• Right-sided heart failure or cor pulmonale (heart swelling and heart failure due to chronic lung disease)
• Pneumonia
• Collapsed lung (pneumothorax)
• Severe weight loss and malnutrition
• Thinning of the bones (osteoporosis)
• Debilitation
• Increased anxiety

Go to the emergency room or call 911 or the local emergency number if you have a rapid increase in shortness of breath.

Not smoking prevents most cases of COPD. Ask your provider about quit-smoking programs. Medicines are also available to help you stop smoking.

Talk to your provider about getting the flu, pneumonia (pneumococcal), COVID-19, and other vaccines.
