That sounds very distressing. I have no idea what your issue is, but I will say that my mom has longstanding, intermittent nausea for which no cause can be determined. I have always pointed out to her that she gets nauseous when her anxiety flares. When she takes meds for her anxiety, the nausea resolves. I hope you can find some answers and help.

Sounds like an acid stomach condition. Do you have "heartburn" as well? Mention this possibility to your doctor. Maybe something like Prilosec might help.

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.
