Stages of COPD
There are four stages of COPD. Your healthcare provider will use your COPD stage to determine your COPD severity and guide your treatment. To stage COPD, your healthcare provider will look at your spirometry or other pulmonary function test results, risk or history of exacerbations, symptoms, and other health conditions.
Four Stages of COPD
Mild
You may have little to no symptoms, but if you walk on an incline or exercise, you may have symptoms like shortness of breath.
Moderate
You may have more symptoms regularly and feel out of breath while walking on flat surfaces or a longer distance.
Severe
You may experience daily symptoms. These symptoms may be more troublesome, and you may have a harder time completing daily activities.
Very Severe
You may find everyday activities difficult because of your symptoms, have less energy and may have low oxygen levels.
COPD is a progressive lung disease, which means it will get worse over time. However, there are many things you can do to slow the progression of the disease. At each stage you are at risk of having COPD flare-ups or exacerbations. Your healthcare provider will work with you to find the best treatment options, which are available at every stage of COPD.
How Is COPD Treated?
Each person's COPD symptoms and treatment options are different. You and your healthcare team will work together to create a treatment plan that works for you. Your treatment plan will help you control your symptoms and know what to do when your COPD gets worse.
There is no cure for COPD, but treatment options may help you:
- Better control symptoms
- Slow the progression of the disease
- Reduce the risk of exacerbations or flare ups
- Improve your ability to stay active
COPD Treatment Options
Warning about over the counter (OTC) portable oxygen concentrators: You may have seen online advertisements for non-prescription, portable oxygen concentrators (POCs). While these are often more affordable, if you have a lung disease like COPD or pulmonary fibrosis, which requires you to use prescription oxygen, these OTC devices may not meet your oxygen needs and it would be important to speak with your health provider before purchasing.
Learn more about portable oxygen concentrators at Lung.org or contact the Lung HelpLine at 1-800-LUNGUSA (1-800-586-4872 and press 2) or submit a question.
