The condition known as Emphysema is the progressive loss of lung function that is commonly attributed to long-term smoking.
Along with asthma and chronic bronchitis, emphysema belongs to a group of lung diseases known as chronic obstructive pulmonary disease (COPD). This chronic lung disease mainly affects the air sacs or alveoli in the lungs.
Emphysema is marked by a reduction in the total number of alveoli, extension of the remaining alveoli along with the progressive destruction of the walls of these remaining alveoli.
Symptoms usually include shortness of breath, long-term cough, fatigue, sleep and heart-related problems, weight loss, and depression.
