WHY. Six months ago I had my pulmonary testing done, and my FEV1 was 45%. This time when I was tested by same doctor my FEV1 was 37%. It was the same with all the other lung function testing; all the test results were lower than six months ago. I have not smoked in over a year. I walk at least twice a day. I have never missed the medicine I am told to take. I use my oxygen most all the time as I’ve been told to do. I do breathing exercise, lifting exercise for upper body strength for breathing muscles. I eat low-sodium foods. I’m always saying, “I can’t eat that,” or “I can’t go there.” I’m not a couch potato. I get out. I love my walks. I never push myself too hard. wouldn’t want to do anything to make myself worse. So I’m wondering WHY? I thought the numbers would at least stay the same… I’m a little depressed about this. I have been in self-pity for two days now, and figure why bother with the exercise and diet. I guess I will give myself one more day to wallow in my self-pity then I will began again, because It’s human nature to try to survive. Has anyone else had this happen to them? Your test results showing the numbers dropping?
