No. That would be a really long shot.
iron overload disorder causes iron to load onto heart and and causes many of the symptoms you describe. I am trying to spread the word about a little understood and rarely diagnosed common condition that affects so many people and they don't know it and the dr are missing it until too late or damage extensive.
At least rule it out, as you research hemochromatosis. My husband was diagnosed a month ago, he is 57 and spent 10 years trying to figure out with drs what was wrong.
