@dantona1977- Welcome to Mayo Connect. Please don't take my 5 lbs to the bank as a norm. I was giving it as an example of how weight affects my breathing. It might not be the same for you. I was mentioning it because I asked my pulmonologist what the main cause of SOB was in his opinion and he said obesity. He also suggested life changes (exercise, and better, cleaner eating). SOB oftentimes isn't caused by the worst-case scenario. But they are certainly something to tweak your mind and question if you have symptoms that should be investigated thoroughly. I'm sorry that the link made you feel worse. I try and give as much information that could possibly help us understand more or lead to better self-care. Does this make sense?
