I'm confused. Many of you have read my posts and provided great support. In March, dr #1 diagnosed my son with PI based on pancreatic stimulation (secretin) test during endoscopy. Four out of five digestive enzymes were below normal. Dr#1 said this represented "mild-moderate PI." He prescribed enzymes and my son gained 4 pounds since March and his diarrhea got better. Fast forward to today, my son was just discharged from nearly 3 weeks in hospital, from acute pancreatitis and ileus. Dr #2 (2nd opinion dr) says ignore pancreatic stimulation test since his fecal elastase has been >500. Still pending fecal elastase from last week. Dr#2 stopped enzymes and now it's wait and see. Back to March weight due to hospitalization
