I, too, have recurrent multi-day episodes of nausea. Sometimes worse days than others. I heard a ve gastroparesis which is slow emptying of the stomach for which I take Reglan (metachopramide) and zofran which help. However, that doesn't explain the episodic nature of the symptoms. I recently met with a new gastroenterologist who has ordered a couple of test to see if we can find a cause. Results of one test show a high degree of inflammation. But that's just an indicator and not diagnostic. Next scheduled test is an MR Enterography for a detailed look at my small intestine and surrounding organs. To be continued.

I'm keeping a diary of foods I eat, exercise and levels of nausea to see if I might be able to identify a trigger food. So far high fat foods seem to be a problem--no more pizza or baby back ribs! I'm a double lung transplantee so I take many drugs which may complicate a diagnosis.
