I don't have your answer, sorry - but, can you get a second opinion bringing the new GI all the facts? And, I can't blame you for not wanting to stay on one of those drugs, if you don't truly need to. My son, who does have severe IBD - UC that would bleed him out in 3 weeks - only got worse on Entivyo. But, they still talked us into keeping him on it for 7 months (mistake). We exhaused all the meds - his colon is out now.
