Before going down the Proton Pump Inhibitor, or
pH Blocking Medication highway. I would suggest that you get a
pH Diagnostic test, not one that uses a naso-gastric tube, which can be higly traumatic. It is very possible that you are suffering from Hyperchlorhydria, or the over Production of HCL by the Guts Parietal Cell. This condition will lead to Delayed emptying, or marked delayed emptying of the Gut. Patients with Hyperchlorhydria will retain nutrients in the Gut.
