Okay...just emailed our CF nurse asking about enzyme dosing. Ellie takes 8 - 9 "beads" of Pancrease MT4's (Lipase 4,000U, Amylase 12,000U, Protease 12,000U) with each feeding. She's still primarily on fortified formula as her amount of solid food intake is minimal. Tonight was the first time I actually saw oil separation in her stool, but they've always appeared greasy. The volume of food consumed hasn't increased, yet she's also having BM's 2 -3x times daily, up from 1 - 2x daily from a couple of weeks ago. Can one become "desensitized" to enzymes? I'm hoping the nurse will contact the CF nutritionist and get back to us soon!! FYI, she's severely PI. Any thoughts?
