Difficult to say. The resolution of gastric dumping would vary from patient to patient. Typically, delayed gastric emptying, rather than gastric dumping, would produce more nausea. Increasing the amount of fiber in the diet may help.
You can also consider a 24-hr pH study and esophageal motility studies to evaluate the symptoms.
An MRCP and/or Sphincter of Oddi manometry can be considered, as symptoms like a biliary duct stone or Sphincter of Oddi dysfunction can lead to nausea s well.
These options can be discussed with your personal physician, or in conjunction with your GI physician.
Followup with your personal physician is essential.
