I have Crohn s and several other autoimmune diseases. The most painful is interstitial cystitis, and I seem to be having a significant flare right now. Despite taking PPI and H2 blocker for nearly 15 years, I have developed erosive gastritis, which I cannot seem to quell. My Gastro MD has suggested IBgard, but I am hesitant -- peppermint is known to irritate the interstitial bladder, and I imagine it would exacerbate my GERD. I am willing to accept a possible dx of IBS now, in addition to my IBD. But it appears that IBgard deals more with lower abdomen distress, and my abdominal discomfort is definitely upper. Colonoscopy and EGD this summer revealed the erosive gastritis. My Crohn s is relatively quiet. Can IBgard help with upper abdominal discomfort, without exacerbating interstitial cystitis and/or heartburn?
