In the last 6 months is loosing weight has diarrhea 2 times a day . He was told to increase his creon to 3 capsules with each meal... Is also itchy ...blood work shows c 19 has gone from 29 to 70 . MRI shows no evidence of cancer we are waiting to have a endoscopy done. Not sure what to do about diet ..any thoughts on what might be going on??
