Chronic nausea/vomiting for 1.5 yrs. No anxiety. Had an EGD, gastric empty study, upper GI & bowel followthru, brain MRI- all normal. Possible causes?
N/V. Sounds like most common causes have been ruled out. Do you have bouts related to your menstrual cycle? Catamenial N/V has been described. Chronic anxiety can also cause this. Medications can be similar. Finally despite normal GES you can have gastric dysmotility, and or gastropersis. GES is not always abnormal.
