Medications.: Mild gastritis can do it. GERD is a possibility. Are you taking any medication on a regular bases. has your gall bladder been evaluated. Inflammatory bowel disease needs to be ruled out. Irritable bowel syndrome a possibility. Consider seeing a gastroenterologist.

A lot: Pelvic ultrasound,gall bladder ultrasound,stool studies, sprue or celiac disease test ,CBC, CRP . If these are normal ,then maybe a colonoscopy .need ur family history.any cancer, obesity,diabetes,allergies,hypothyroidism could guide ur doctor.if overweight, please lose weight.if drinking too much soda or diet soda-STOP.

Persevere-vague prob: For vague abd/GI probs other helpful tests: stool analysis for infection, eval for food allergy (try elimination diet), and colonoscopy. Recheck CT for subtle submucosal edema of Lt colon - early ulcerative colitis can be tricky. If still no cause, consider IBS (irritable bowel syndrome). Often stress-related- gastritis due to stress can be a hint. Prob wise to avoid alcohol too.
