Signs and Symptoms of Emphysema Symptoms of emphysema vary from mild to severe and include shortness of breath (dyspnea), cough, and difficulty breathing upon exertion (e.g., exercise). Emphysema is a chronic (long lasting), progressive condition, which means the symptoms usually worsen over time.

The pulmonary system gets damaged due to regular smoking and addition of toxins on the lung area. The condition of COPD might get chronic with time as the disease is incurable.
