Hello, This sounds exactly like what our daughter went through. She was diagnosed with CF around age 3 and wasn't absorbing hardly anything at that point. She was started on Creon-5 (and Prevacid, etc.) and that seemed to help a little bit. One year later when we took her to Stanford for a liver transplant eval, they said she needed to improve her nutritional status and suggested we discuss a g-tube with her GI doc. Since she had an NG tube at age 3 with no positive results, we didn't think it was a matter of getting MORE food into her tummy, it was absorbing it. They also suggested we switch her to Pancrecarb MS-8 enzymes which are developed to help with the bicarbonate secretion deficiency. We saw an immediate improvement once she switched to Pancrecarb. She had weighed 30 pounds for two years prior to switching, and within 4 months after switching, she gained 6 pounds. Her nutritional status improved immensely and her b.m.'s look great and "normal". This has been our experience and I hope you will soon find a solution to your child's problem. Take Care. Kelli
