How does COPD affect the body?
As we mentioned, obstructive means you have trouble getting air out of your lungs. Why is this? With COPD the lungs have been damaged. This tends to make them stretched out and over-inflated, and lose
some of their elastic quality. We all know that a new balloon quickly goes back to its small size when you let the air out of it. But a balloon that’s been blown up many times is not as elastic as it once was, and it’s not as good at getting the air out. Lungs with COPD can be that way too, and if you can’t blow out the air you should, it’s harder to take your next breath.
So, when you are short of breath, of course, you’re going to want to sit down more and not be as active as you once were. Moving around less can make your muscles weak and your joints stiff. If it hurts to move around, you’re going to be even less active. The more sedentary you are, the less you can do, and the more frustration and anxiety you might have. Your breathing becomes more shallow (you are working very hard to huff and puff without moving much air) and this can be exhausting — and depressing.
Also, the heart and lungs work closely together to make sure enough oxygen gets around to all parts of our bodies. When the lungs are working too hard, more stress is put on the heart. So, COPD can affect not only the lungs but other body systems, your muscles, your brain… other parts of your body can begin to struggle to keep up with what they need to do.
