COPD stands for Chronic Obstructive Pulmonary Disease. It is a long-term lung condition that makes it hard to breathe because the airways become narrowed and the air sacs in the lungs are damaged.
Key facts
Yes, COPD is a common condition, especially among people over 40 who have smoked.
It mostly affects people over 40, particularly those who have smoked for many years or been exposed to lung irritants like dust, fumes, or pollution.
Doctors diagnose COPD using a combination of your medical history, a physical exam, and lung function tests.
You will be asked about your symptoms, smoking history, and any exposures. The tests are usually painless, though some may make you cough. Always tell your doctor if you feel dizzy or very short of breath during a test.
Treatment for COPD focuses on relieving symptoms, slowing the progress of the disease, and improving quality of life. It includes lifestyle changes and sometimes medications or other therapies.
Your doctor may prescribe inhalers that help open your airways. Other treatments include pulmonary rehabilitation (a program of exercise and education), oxygen therapy, and in some cases, medications to reduce flare-ups. Always take your medicine exactly as prescribed and never change your dose without talking to your doctor.
Living with COPD means managing your breath. Learn techniques like pursed-lip breathing to control shortness of breath. Plan your activities so you do not get overtired. Keep a healthy weight and avoid lung irritants like smoke and strong fumes.
A balanced diet helps you maintain a healthy weight. Eating smaller, more frequent meals can prevent bloating. Regular gentle exercise, like walking, can strengthen your breathing muscles. Ask your healthcare team for a plan that is safe for you.
Living with a long-term breathing condition can cause anxiety or depression. It is normal to feel worried. Talk to your doctor about support, including counselling or support groups.
While COPD cannot always be prevented, you can lower your risk by not smoking and by avoiding lung irritants such as dust, fumes, and air pollution.
Yes, getting the flu vaccine and the pneumonia vaccine can help prevent infections that make COPD worse.
If you are over 40 and a smoker, ask your doctor if you should have a spirometry test to check your lungs early.
With good care, many people with COPD lead active lives for many years. Treatment can relieve symptoms and improve your quality of life. Although COPD is a long-term condition, you can take steps to feel better.
