Why is my digestive system always messed up?
I'm 18 and I'm sensitive to eating too much sugar and grease and sometimes I feel sick just smelling it. My junior year I had painful intestinal issues every morning. I stopped eating uncrustable sandwiches and I felt better but I still have problems. I'm not allergic to peanut butter, milk, jelly, or bread. Every once in awhile I have diarrhea issues. I can't find what's setting this off. Help?
