I have read ALL the responses that I got on my new entry and I thank you all. The biggest problem I have had since"now" I can remember is breathing. My reproductive has not been affected and I think my digestive is doing pretty good, but my biggest problem is my breathing. I quit smoking for my son for many years after he was diagnosed, but sadly have one or two since he left us...you know the excuses...anyway, I am in the Army(17yrs) and have always struggled with my running(breathing). I also have been diagnosed with severe sleep apnea. It took me a little time, but now I am wondering, if I have the gene to pass on and combine...how is it affecting my body, even in an abstract way. Did I understand one of the responses...having a child with CF definetly says I have the gene, but are there tests to show what it is doing to my body, or is it ALL in my head and I only get anxious when I get short of breath, because I know that is the way my son left us. Thank you all for your responses.
