Thank you for responding if only I can get a doctor to want to do all those things
There are many potential causes of bloating after meals. If this started after an abdominal surgery the potential for partial obstruction should be ruled out. This is typically done with a small bowel series but an abdominal and pelvic CT scan would also be appropriate. Delated gastric emptying could be an issue as well and is readily measured with a simple test. In brief, a thorough and thoughtful evaluation would be expected to provide a reason.
