I just wrote a note to someone about how frustrating it has been for me to not see a direct pattern between a food I have eaten, and how my bladder feels. What I have come to realized is that, my digestion or inability to digest food properly is an expression of my IC. Dr. Brizman has discussed this with me. For me, if I have burping, heartburn, pressure in the chest, bloating, gas (foul smelling or not), constipation or loose stools, or undigested food in my stools, these to me are all signs that the food I am eating is somehow contributing to my IC.
