I don't have D or C with this fullness. All that happens is that I have a feeling of fullness or bloating after I eat. I've had upper Gi and colonoscopy - two GI docs say I have IBS. They gave me different things to take - nothing is helping. Now they think it is anxiety and want me to try those meds. I am convinced there has to be something causing this. Does anyone have a similar problem? Does this sound like IBS? What can I do to stop this?
