Emphysema information from trusted sources:
Emphysema is a long-term, progressive disease of the lung that primarily causes shortness of breath. In people with emphysema, the lung tissues necessary to support the physical shape and function of the lung are destroyed. It is included in a group of diseases called chronic obstructive pulmonary disease or COPD (pulmonary refers to the lungs). Emphysema is called an obstructive lung disease because the destruction of lung tissue around smaller airways, called bronchioles, makes these airways unable to hold their shape properly when you exhale. This group of diseases ranks as the fourth leading cause of death in the United States. Unlike heart disease and other more common causes of death, the death rate for COPD appears to be rising.
Emphysema is a type of chronic obstructive pulmonary disease (COPD) involving damage to the air sacs (alveoli) in the lungs. As a result, your body does not get the oxygen it needs. Emphysema makes it hard to catch your breath. You may also have a chronic cough and have trouble breathing during exercise. The most common cause is cigarette smoking. If you smoke, quitting can help prevent you from getting the disease. If you already have emphysema, not smoking might keep it from getting worse. Treatment is based on whether your symptoms are mild, moderate or severe. Treatments include inhalers, oxygen, medications and sometimes surgery to relieve symptoms and prevent complications.
Emphysema is a factor in the progression of chronic obstructive pulmonary disease (COPD), a condition that limits the flow of air when you breathe out. Emphysema occurs when the air sacs at the ends of your smallest air passages (bronchioles) are gradually destroyed. Smoking is the leading cause of emphysema.
Chronic obstructive pulmonary disease
Chronic obstructive pulmonary disease (COPD) is the name for a collection of lung diseases including chronic bronchitis, emphysema and chronic obstructive airways disease. The main symptom of COPD is an inability to breathe in and out properly. This is also referred to as airflow obstruction.
Emphysema (em-fi-SEE-mah) is a long-term disease of the lungs. Emphysema is one of a group of lung diseases called COPD, or chronic obstructive pulmonary disease. Emphysema causes damage to the alveoli (al-VEE-oh-lie) that cannot be reversed (cured). The alveoli are the tiny air sacs of the lungs where oxygen is put into the bloodstream. With emphysema, your lungs become less able to take in oxygen (good air) and get rid of carbon dioxide (deye-OKS-eyed). Carbon dioxide is an invisible gas that your body gives off as a waste product.
