My son is 9 months old. He has been on enzymes since he was 3 weeks old. He has always taken 1 ultrase before meals. Other than reflux, he has never had any issues at all and shows no signs of CF yet. He has always been 90th percentile + in weight and height. They did a stool sample at 3 weeks and I was told his pancreatic enzymes were a little low, so they put him on enzymes. However, his stool has been stinky, but never been strange. it has never been greasy. I notice he strains a lot and sometimes nothing is produced. Sometimes, it is pellets. I am concerned that he doesn't even need them. I know that is rare. I am keeping detailed records on him right now and plan to ask at his clinic visit next month, but I thought I would ask here too. Sometimes i only give him 1/2 an enzyme if it has been recent since he had the last one. I also have been nursing him at night with no enzymes since he was very young, with no complications. I posted this on another website and someone mentioned having him retested to see if he is pancreatic sufficient now. Can that be possible? Any help is appreciated! Thanks!!!
