If you have chronic obstructive pulmonary disease (COPD), you’ve probably heard your doctor or pulmonologist talk about the GOLD COPD stages. Because the GOLD system is a way for doctors to categorize COPD stages, it’s often used to better understand the severity of symptoms. While COPD is a chronic, progressive disease, meaning it will worsen over time, COPD affects everyone differently and at different rates. There’s no way to accurately predict COPD prognosis or COPD life expectancy. However, there are ways to measure and estimate symptoms and severity, such as with the GOLD COPD stages.
What is COPD?
COPD is a progressive lung disease that includes emphysema and chronic bronchitis. COPD ranges from mild to severe and is characterized by the restriction of airflow into and out of the lungs. Symptoms include shortness of breath, constant coughing, fatigue and production of excessive amounts of mucus.
Emphysema often accompanies a COPD diagnosis and gradually destroys the tiny air sacs (alveoli) of the lungs. Emphysema also damages the elasticity of the airways that lead to the air sacs. In chronic bronchitis, the air passages in the lungs become inflamed. In response to the inflammation, the lungs produce excess mucus, causing painful coughing and sputum.
What is the GOLD Staging System?
Many doctors use more than one way to determine your COPD stage. One common way to measure COPD stages and severity is with the GOLD staging system. The Global Initiative for Chronic Obstructive Lung Disease or GOLD came up with the GOLD system. The GOLD system uses your forced expiratory volume (FEV1) test from your pulmonary function test to categorize the severity of your COPD into stages. Simply put, FEV1 means the amount of air you can forcefully exhale in 1 second. As the severity of COPD progresses, the stage number shows how airflow is limited.
What are the GOLD COPD Stages?
Simply put, the GOLD COPD stages break down into 4 total stages. Over time, COPD symptoms will worsen, and the stage numbers will increase.
- Stage 1: Very mild COPD with a FEV1 about 80 percent or more of normal.
- Stage 2: Moderate COPD with a FEV1 between 50 and 80 percent of normal.
- Stage 3: Severe emphysema with FEV1 between 30 and 50 percent of normal.
- Stage 4: Very severe COPD with a lower FEV1 than Stage 3, or those with Stage 3 FEV1 and low blood oxygen levels
Remember, seeing your doctor regularly to keep track of your GOLD COPD stages and other measurements, such as BODE index and pulmonary function test, is important. Being proactive in your healthcare is essential to improving and maintaining your quality of life.
What can you do to improve your quality of life?
While lung damage caused by COPD is irreversible and COPD is progressive, there are treatments available to help you. Your doctor may prescribe medications, inhalers, oxygen therapy or pulmonary rehabilitation to manage your COPD symptoms. Alternative treatments such as stem cell therapy have also helped many people regain their quality of life. In fact, some people have even been able to reduce their oxygen therapy use after treatment, and many people find their daily activities easier to perform. If you or a loved one has COPD, emphysema, chronic bronchitis, pulmonary fibrosis or another chronic lung disease and would like to learn more about stem cell treatment, contact us at (800) 729-3065.
