Why does having emphysema make it difficult to breathe?

Emphysema is a chronic lung disease that causes damage to the alveoli, which are the small air sacs in the lungs. This damage makes it difficult for the lungs to exchange oxygen and carbon dioxide, which can lead to shortness of breath and other breathing problems.

Here are some of the ways that emphysema makes it difficult to breathe:

* Alveolar destruction: Emphysema causes the destruction of the alveoli, which are the tiny air sacs in the lungs. This reduces the surface area of the lungs available for gas exchange, making it more difficult for the lungs to take in oxygen and release carbon dioxide.

* Loss of elasticity: Emphysema also causes the loss of elasticity in the lungs. This means that the lungs are less able to recoil after they have been inflated, which makes it more difficult to exhale.

* Increased airway resistance: The damage caused by emphysema can also lead to increased airway resistance. This means that it is more difficult for air to flow in and out of the lungs, which can cause shortness of breath.

* Inflammation: Emphysema is also characterized by inflammation in the lungs. This inflammation can damage the airways and make it more difficult to breathe.

These are just some of the ways that emphysema makes it difficult to breathe. Emphysema is a serious disease that can significantly impact a person's quality of life. If you have any of the symptoms of emphysema, it is important to see a doctor right away.
