I was dx with CF at 15 years old. My doctors had tried to diagnose me with CF since I was 2 after severe sinus problems and lung problems started to develop. I had inconclusive sweat chloride tests at age 3 and 7, but had a positive test at 15 when my doc at the mayo clinic sent me for another one. My lungs improved greatly and even exceeded a healthy persons capacity while I was swimming competitively through late elementary school, JHS, and HS. Then in my 10th grade year my pancreas started to not work properly. I have severe problems with my bile ducts and have had a 6 pancreatic stint procedures, whipple, puestow, and a partial pancreatectomy. After all these surgeries I couldn't keep up with swimming. Ever since then my lungs have been getting increasingly worse. I still consider myself VERY lucky as I am still here at age 25 <img src="i/expressions/face-icon-small-smile.gif" border="0"> and the docs said I wouldn't make it into my teens HA! I love proving doctors wrong, it's fun. I'm glad to see others had late a diagnosis as well, makes me feel like I'm not such a wierdo after all <img src="i/expressions/face-icon-small-smile.gif" border="0">
