Understanding Emphysema

Emphysema is a lung condition that causes shortness of breath that becomes gradually worse over time and can occur during daily activities or even while resting. People with emphysema have a damaged alveoli, which causes old air to become trapped in the lungs, and leaves little room for fresh air to enter. Emphysema is most commonly caused by long-term exposure to airborne irritants, such as tobacco smoke, air pollution, and chemical fumes and dust.
