Stage 2 – Moderate Emphysema
In stage 2 of emphysema, the airflow limitation starts to get worse. Some common symptoms of this condition also become more obvious. These might include shortness of breath, increased production of mucus, and a chronic cough. During a breathing test, your doctor would notice the blockage of airflow due to the buildup of sputum. This leads to a low level of oxygen in your bloodstream and triggers some health issues. Most people often seek medical treatment at this stage. [2]
