I am not sure as I have often wondered as you. I also had a doctor this week feel that my issues could have to do with my ibs and having so much inflammation in my gut for so long.Have you been tested for allergies or other things like gluten? The only other doctor who even touched on the nutrition part was a holistic one. I am not big on that but at this point I would be willing to try as long as it encorporates regular meds and treatments. Could you try to eliminate certain things from your diet and see but be careful to make sure you get proper nutrients
