Thanks for the response. Yes, negative for celiac. I have also tested negative for crohns, colitis, thyroid malfunction, autoimmune (ANA panel normal), epstien barr, endocrinology disorders, gallbladder issues, etc. Had a normal colonoscopy, although it had signs of irritation in the intestines, stomach, and esophagus. I had a normal CT scan, normal abdominal ultrasound and normal pill cam. So I'm not sure whether I accept that this is IBS despite the lack of traditional symptoms, or pursue a different diagnoses.
