Get an evaluation: It is likely you will require several studies beginning with an exam and proceeding to endoscopy and motility studies as well as possible stool cultures or analysis.

Need to examine: It is not feasible to provide a meaningful opinion without additional history, physical examination and may be some tests. If you have lost weight it is imperative that you consult a GI specialist. If you have not lost weight, you may wish to try different foods and eliminate those that cause symptoms.
