Define emphysema??

Emphysema is a chronic lung condition characterized by the destruction of the air sacs in the lungs, known as alveoli. This leads to difficulty breathing and reduced oxygen intake. Emphysema is often caused by long-term exposure to irritants such as cigarette smoke and air pollution. Symptoms of emphysema include shortness of breath, coughing, wheezing, and chest tightness. Treatment typically involves medications, pulmonary rehabilitation, and in severe cases, oxygen therapy or surgery.

Emphysema is a chronic lung disease that causes shortness of breath. It is characterized by damage to the air sacs (alveoli) in the lungs, which leads to a loss of elasticity and an increase in air trapping. This makes it difficult to breathe, especially during exercise.

Emphysema is most commonly caused by smoking, but it can also be caused by exposure to other irritants, such as air pollution, dust, and fumes. It is a progressive disease, meaning that it gets worse over time. There is no cure for emphysema, but treatment can help to slow the progression of the disease and improve symptoms.
