I have been going to a gastroenterologist for nausea and vomiting on and off for 10 years.  The past several months it has gotten worst.  I have had an endoscopy, gastric emptying study and an Upper GI with small bowel follow through.  Everything keep coming back negative except for a hiatal hernia.  Could this be the reason why I have the nausea and vomiting along with sometimes diarrhea?
