Just wondering if anyone was diagnosed later on and only had digestive issues? And if so when did your digestive symptoms first present themselves? My nephew is 11 and is having stomach problems....loose stools (diahrea sp?) and stomach cramps. I dont think it floats or is greasy but I am not positive. He was a very large baby and toddler but now is very skinny. I dont think his mother mentioned cf to the doctor but the doctor did say he was too old to just now be having symptoms of something genetic. He has never had any lung problems. I was just wondering if he should be tested for cf just in case. My son has cf so it does run on our side of the family. Thanks
