Bronchitis and emphysema are two chronic lung diseases that fall under the umbrella term of chronic obstructive pulmonary disease (COPD). The main contributing factor is smoking. It can be controlled with bronchodilators and lifestyle changes, but it typically gets worse over time. Over time, COPD causes damage to your lungs. It could begin with minor symptoms before getting worse. Treatment can lessen symptoms and delay the onset of the disease.
