Shortness of breath causes include so many different troubles that can cause this malady. I personally have endured shortness of breath for a year and a half now. I have been diagnosed with asthma, but other than it being a shortness of breath causes diagnosis, I am not so sure it was correct. I feel I have a constriction of my blood vessels in my lung area, not allowing enough blood flow into my lungs, which then causes lack of oxygen to my body when needed during exertion.
I have found a great product that dialates my circulatory system gives me more oxygen immediately!.. In addition I have also discovered a nano-technology product that has a video that will blow you away on what it will do for your blood, and the 500 functions your kidneys need to perform! Use them both and breathe again my reader!
