Hello, in response to your question about GI problems, my son who just turned 2 has mainly GI problems with his CF. He suffers from pancreatic insuffiency and malabsorption. He also has acid reflux. He is on several medicines for this (zantac, prilosec, reglan, and pancreatic enzymes.) He also had a feeding tube placed thru his stomach to provide supplemental nutrition ( a GJ tube) about 3 months ago. He was diagnosed at birth with his CF, there is mandatory newborn screening here in Pennsylvania. I am sure that he probably would have been misdiagnosed with something else because he doesn't have the classic Lung problems yet associated with CF. He is doing quite well Thank God <img src="i/expressions/face-icon-small-smile.gif" border="0"> He has been treated since the day he was diagnosed, both for GI and Lungs. He gets breathing treatments and chest PT 2-4 times a day just precautionary/preventive to keep his lungs healthy. Hope this helps you out.Donna mother of Mikey 2 Y.O. with CF
