Understanding COPD: A Guide for Patients
Chronic Obstructive Pulmonary Disease (COPD) is a common and serious lung condition that makes it harder to breathe over time. While there is no cure, treatments are available that can help manage symptoms, reduce flare-ups, and improve your quality of life. Ongoing research is also exploring new ways to treat and better understand the disease.
What Causes COPD?
COPD usually develops after long-term exposure to harmful substances that irritate or damage the lungs — most often cigarette smoke. Other causes include air pollution, exposure to dust or chemicals at work, and in rare cases, a genetic condition called alpha-1 antitrypsin deficiency.
Did you know? Up to 90% of COPD cases are linked to smoking, but not everyone who smokes will develop the disease.
What is COPD?
COPD is a term used for a group of chronic lung diseases that block airflow and make it harder to breathe. It causes lasting damage to lung function.
When you breathe in, air travels through the windpipe into the bronchi, which branch like a tree into smaller airways called bronchioles. These lead to tiny air sacs called alveoli.
In the alveoli, oxygen moves into your blood and carbon dioxide is removed when you exhale.
With COPD, the airways may be inflamed, and the bronchioles and alveoli can be damaged. This makes it harder for the lungs to absorb oxygen and remove carbon dioxide, leading to breathlessness and reduced energy.
Common Symptoms of COPD
COPD symptoms often begin slowly and worsen over time. They may be mistaken for aging or other illnesses at first. The first symptoms and complaints of COPD are often morning cough and increased mucus production. Other common symptoms include:
-
Shortness of breath, especially during physical activity.
-
A long-lasting cough, often with mucus.
-
Wheezing or a whistling sound when breathing.
-
Frequent chest infections.
-
Feeling tired or lacking energy.
-
Difficulty breathing during everyday tasks.
COPD can also cause sudden flare-ups, where symptoms become worse very quickly and may require urgent care.
Did you know? Many people do not realise they have COPD in the first stages of the disease, because it's mistaken for other illnesses.
How is COPD Diagnosed?
-
Doctor’s Visit: Your doctor will ask about your symptoms, smoking history, and any workplace exposures.
-
Spirometry (Breathing Test): You’ll blow into a device that measures how much air you can breathe in and out. This helps confirm the diagnosis.
-
Imaging Tests: Chest X-rays or CT scans may be used to look at your lungs and rule out other conditions.
-
Blood Tests: These can check for other issues or look for markers linked to certain types of COPD.
Did you know? COPD is often diagnosed only after it has progressed, but early testing can help start treatment sooner, slow disease progression, and improve quality of life.
Treatment Options
Although there is no cure for COPD, many treatments can help you live more comfortably and stay active. Your doctor will create a treatment plan based on your specific symptoms and health needs.
-
Inhalers: Medicines that help open your airways and make breathing easier.
-
Pulmonary Rehabilitation: A program that includes exercise, education, and breathing techniques.
-
Oxygen Therapy: For people with low oxygen levels in their blood.
-
Lifestyle Changes: Quitting smoking, eating well, and staying physically active.
-
Clinical Studies: Some patients may qualify for research studies testing new treatments.
Living Well with COPD
Even small steps can help improve your well-being if you live with COPD:
-
Quit smoking: This is the most important step you can take. It slows the disease and improves your quality of life.
-
Stay active: Gentle movement, like walking, helps maintain lung function and reduces breathlessness.
-
Eat well: A balanced diet can help keep your energy up and support your immune system.
-
Attend a COPD program: Many hospitals and health services offer educational courses or pulmonary rehabilitation to teach breathing techniques, exercises, and how to manage symptoms.
Did you know? Quit smoking is one of the most important things you can do to manage the progression of COPD.
Clinical Studies
There are currently clinical studies investigating potential treatments for COPD, and you can find out more about that here.
Final Thoughts
Living with COPD can feel overwhelming at times — but you’re not alone. With the right care and support, many people continue to lead full and active lives. Reaching out to others through support groups, patient organizations, or online communities can also be a great source of strength.
