Emphysema is one of the conditions that include COPD (chronic obstructive pulmonary disease). Emphysema affects gradual damage of lung mass, especially destruction and thinning of the air sacs/alveoli. Emphysema is normally followed by chronic bronchitis, with phlegm and daily cough. People with emphysema encounter conciseness of breath with exercises. It is not temporary, but there are medications that can assist you to control the condition.
