What is empheseyma?

Emphysema is a chronic lung disease in which the air sacs (alveoli) in the lungs are damaged and enlarged, causing shortness of breath, wheezing, and coughing. It is a type of chronic obstructive pulmonary disease (COPD).

Emphysema is caused by damage to the alveoli, which are small air sacs in the lungs that allow oxygen to pass from the air into the bloodstream. When the alveoli are damaged, they become less elastic and can no longer expand and contract properly. This makes it difficult for oxygen to get into the bloodstream, and can lead to shortness of breath, wheezing, and coughing.

Emphysema is most commonly caused by smoking, but it can also be caused by other factors, such as exposure to air pollution, dust, or chemicals, and certain genetic conditions.

Emphysema is a progressive disease, which means that it gets worse over time. There is no cure for emphysema, but treatment can help to relieve symptoms and slow the progression of the disease. Treatment options include smoking cessation, medication, oxygen therapy, and surgery.
