I have been experiencing GI symptoms for approximately 11 months and although they have done a variety of testing they cannot determine a diagnosis. I have been exeriencing abdominal pain and bloating, acid reflux, and burping following eating and drinking, nausea, weight loss, and loss of appetite. I have an extensive family history of diabetes, including my father - however they have not done any testing for diabetes and I wonder if these are symptoms of possible diabetes.
