If you’ve been diagnosed with chronic obstructive pulmonary disease (COPD), the next step will be understanding the stages of COPD. The Global Initiative for Chronic Obstructive Lung Disease (GOLD) grading system classifies the disease into four grades according to its severity.Here’s what you need to know about the four GOLD stages of COPD.
Grade 1: Mild this disorder. Many people with mild COPD having some airflow limitation, but may be unaware that their lung function has started to decline. You may not yet have any COPD symptoms, or you may have symptoms of chronic cough and excessive mucus.
Grade 2: Moderate COPD: At this stage, airflow limitation worsens and you may start to notice symptoms, particularlyshortness of breath upon exertion along with cough and sputum production. Symptoms may seem more problematic to people at this point, and this is when most people typically seek medical treatment.
Grade 3: Severe COPD: Once the disease has advanced to this stage, limitation of airflow significantly worsens, shortness of breath becomes more evident and this disorder exacerbation is common. If you reach this stage, you may notice a decrease in your activity tolerance and you may fatigue more quickly than usual.
