My son is 18 and has been suffering with morning nausea/vomiting for the past 2.5-3 years. Nothing that we have tried helps. He has been seeing a gastrointerologist for the past 2 years and has been put on omeprolozone for reflux in the morning and at night. It hasn't helped. He has been tested for different allergies to various foods, etc, but everything came back negative. He is trying to start his career but the nausea is making it difficult to get to work every day. It is also why he decided on a different career path because he didn't wan't to have to go away to college and continue dealing with all the problems he has had in high school. I'm hoping you can find a solution. I've looked at many of the ideas people have posted and plan on talking with his specialist about it. I can post my findings and maybe we can find something to help. Good Luck.
I've seen a few posts with the same symptoms as I have. I've had all the tests including MRI, Cat Scan, blood work. Now I'm having an endoscopic tomorrow. Then Tuesday, Ultra sound & a heta scan. My husband thinks I should try gluten free for a while. My Dr. (gastroenterologist) looked to see if any medication I was prescribed could have triggered the nausea, but nothing was found.
Good luck to you also. I, gonna keep on trying to figure this out and posting what I find.
