Jeanie,   You should definitely speak to your daughter's doctor about her symptoms. But since you've ticked "IBD triggers" in your question line I'll assume she's been diagnosed with UC or Crohn's.   Red meat can be very hard on any gut to digest, plus it can have added preservatives and antibiotics that can play havoc with the gut. Gravy tends to be made with butter, which is fatty, and flour, which contains gluten, either of these things could be triggering your daughter's symptoms. It's relatively common with IBDers.   I recommend she start keeping a food journal where she writes down EVERYTHING she eats and how she feels after eating it. And when you see her doctor to discuss this make sure she takes that in with her to give some idea of whether or not other foods are causing issues.   Good luck to you, Elizabeth
