Other symptoms caused by emphysema include: shortness of breath wheezing weight loss loss of muscle a barrel chest, resulting from overinflation of the lungsWhat is part of lung damaged or destroyed by emphysema?
When emphysema develops, the alveoli and lung tissue are destroyed. With this damage, the alveoli cannot support the bronchial tubes. The tubes collapse and cause an "obstruction" (a blockage), which traps air inside the lungs. Too much air trapped in the lungs can give some patients a barrel-chested appearance.What are the effects of emphysema on breathing?
To put it simply, emphysema causes your airways to collapse and makes it difficult to breathe. The end result is the body not getting enough oxygen. In emphysema, the walls between the tiny air sacs in the lungs lose their ability to stretch. They eventually become weakened and break.
