When one part of our bodies gets sick, it's usually not confined to that part of the body. Everything in the body is connected in one way or another, which means everything, can be affected. If you have COPD, other parts of you can be affected, such as your heart, circulation, and even your mental state.
If you've been diagnosed with a chronic illness or something like cancer, your body will go through some changes. If you have severe asthma, you will probably find yourself unable to exercise, which can cause weight gain and even make you have trouble sleeping. The fact is something serious like this can cause a chain reaction of other medical problems. If we know this, why not prevent them or treat them right away?
