COPD: symptoms, treatment and living with it

In short

• COPD is a common lung disease that restricts airflow. Its main symptoms are shortness of breath, a chronic cough, sometimes with mucus, and tiredness.
• Spirometry, a breathing test, is the main test used to confirm it.
• COPD is not curable, but symptoms can improve. Quitting smoking is the most important step.
• Inhalers, pulmonary rehabilitation, vaccines and, for some people, oxygen make up the rest of the toolkit.
• Ask your clinician for a plan for flare-ups, and call 911 if you cannot catch your breath or talk.

What happens in the lungs

COPD is a group of conditions that block airflow. The two most common are emphysema, which damages the air sacs in the lungs, and chronic bronchitis, which irritates the airways. Because air does not move out freely, you get short of breath, and the symptoms usually develop slowly and get worse over time.

Smoking and air pollution are the most common causes. Long-term exposure to dusts, fumes or chemicals at work can also cause COPD. A rare inherited condition called alpha-1 antitrypsin deficiency can lead to COPD at a young age.

The NHLBI notes that smoking is the main cause in high-income countries, while air pollution plays a larger role in lower-income parts of the world. COPD is a major cause of disability, which is why catching it early and following a treatment plan matter so much.

Symptoms: when to suspect COPD

• Shortness of breath, especially when you are active.
• A persistent cough, often with mucus.
• Wheezing and chest tightness.
• Feeling tired.
• Flare-ups, which are sudden worsening of symptoms.

Not everyone who has these symptoms has COPD, but the NHLBI advises making an appointment as soon as symptoms appear and not waiting for them to become serious. Tell your clinician if you smoke or used to smoke, or if you work around dust, fumes or chemicals.

Many people put breathlessness down to getting older or being out of shape, and they put a cough down to smoking. That is how COPD ends up being found late. Bring up these symptoms at your next visit, even if they seem minor to you.

How a clinician confirms COPD

The main test for COPD is spirometry. It measures how much air you can breathe out and how fast, and it is the test that confirms the diagnosis. A chest X-ray cannot diagnose COPD, but it can find other conditions that may interact with it. A chest CT scan can help find the cause of symptoms such as shortness of breath or chest pain.

Some people have a genetic condition that raises their risk, and your clinician may talk with you about genetic screening. In some cases an arterial blood gas test measures the oxygen and carbon dioxide levels in your blood.

Treatment: the main building blocks

1. Quit smoking or vaping.The WHO calls this the most important thing you can do. It stays important at every stage. Your clinician can help with a plan and with medicines for quitting.
2. Inhaled medicines.Bronchodilator inhalers are the most important medicines for COPD. They relax the muscles around the airways and open them up. For severe COPD or frequent flare-ups, a clinician may add an inhaled steroid.
3. Pulmonary rehabilitation.This is a supervised program that includes exercise training, health education and breathing techniques. Ask your clinician where to find one.
4. Vaccines.The WHO advises getting a flu vaccine every year. Ask your clinician which other vaccines you should have.

Oxygen therapy is used for people who have had COPD for a long time or have severe COPD, and it is prescribed by a clinician after testing. Surgery is usually an option only when serious symptoms have not improved with medicines.

Daily life with COPD

• Eating: smaller meals more often through the day, and rest before you eat. Poor intake can make symptoms worse.
• At home: keep items you use often in one easy-to-reach place, use a wheeled cart, and ask for help making the home easier to move around in.
• Moving: physical activity can strengthen the muscles that help you breathe.
• Mood: living with COPD may cause fear, anxiety, depression and stress. Talk with your clinician or a counselor, and consider a support group.

Flare-ups

A flare-up, also called an exacerbation, is a sudden worsening of symptoms. Call your clinician if your symptoms are getting worse or you have signs of an infection, such as a fever. Talk with them ahead of time about a plan for treating a flare-up, so you know what to do and whom to call.

A severe flare-up needs emergency care. Do not wait to see whether it passes on its own if your breathing is getting harder, and do not stop a prescribed medicine without talking to your clinician first.

When to see a doctor, and red flags

Make an appointment if you have a cough, wheeze or breathlessness that does not go away, particularly if you smoke or smoked in the past. Contact your clinician promptly if your symptoms are worsening or if you have a fever.

Red flags: call 911 if you have a hard time catching your breath or talking, blue or gray lips or fingernails, you are not mentally alert, you have a very fast heartbeat, or your prescribed treatment is not working.

Questions to ask your clinician

• Has my diagnosis been confirmed with spirometry?
• Am I using my inhaler correctly?
• Do I need an inhaled steroid in addition to a bronchodilator?
• Where can I take part in pulmonary rehabilitation?
• What should I do when I have a flare-up?
• Do I need oxygen, and how will that be tested?
