What are the 4 stages of COPD?
The four stages of COPD are mild, moderate, severe, and very severe. The stages are based on symptoms, spirometry testing results, and the number of COPD exacerbations someone experiences.
Key takeaways
There isn't one single test for COPD. Your healthcare provider may diagnose COPD by conducting a physical examination, evaluating your symptoms, and reviewing your medical history. They may also perform a spirometry test, chest X-rays, CT scans, and other tests.
There are two main types of COPD: Chronic bronchitis and emphysema.
There are four stages of COPD, ranging from mild to severe.
4 stages of COPD |
|
|---|---|
| Stage 1 (Mild COPD) | Few symptoms, and the individual may not know that their lung function is abnormal. Treatment typically includes lifestyle changes. |
| Stage 2 (Moderate COPD) | Symptoms worsen, and breathing problems become more apparent. People often seek medical attention at this stage. Treatment may include pulmonary rehabilitation, steroids, and oxygen |
| Stage 3 (Severe COPD) | More severe symptoms, frequent flare-ups, and further decreased lung function. Treatment typically includes the use of an oxygen tank to help with breathing. |
| Stage 4 (Very severe COPD) | This stage is also known as end-stage COPD, with extremely limited airflow and potentially life-threatening flare-ups. Treatment includes surgical intervention, such as a lung transplant or a bullectomy. |
