Nondiagnostic: Your symptoms are nondiagnostic and more information is needed. Although this could be an irritable bowel syndrome,other causes such as gastritis,gluten or lactose intolerance are possibilities. If your symptoms persist,see a gastroenterologist for evaluation and appropriate tests and treatment will be ordered. In the meantime try to see if specific foods bring on symptoms.
