Sporadic vomitting lasting a week

[Camyblue7]

Hi, can sporadic vomitting lasting 5-7 days occurring mostly at night be linked to celiac? My son is almost 11 years old and has had a few episodes where he has horrible stomach pain, diarrhea and vomiting for about a week then it clears up for a few weeks then happens again. He has no fever and no one else in the house becomes sick. During that week he usually vomits a few times during the day but by after dinner time he is throwing up upwards of 10 times during the night. 

A little background information if needed on him. He had reflux and colic as a baby, has a geographic tongue, had speech impairment, multiple learning disorders, has fallen off the growth chart before, always been small and skinny for his age but so is his dad. He just made 64lbs at almost 11. He is lactose sensitive. In 1st grade he had a stomach ache everyday when we switched him to lactose free milk it cleared up and he would only get a stomach ache if he ate too much dairy like a lot of ice cream but he has never thrown up because of it that we are aware of. 

His pediatrician keeps thinking it's just a stomach virus. He had a glucose test today came back fine at 110. Negative for strep and urine came back fine. We are currently on day 5 of his throwing up for a 3rd episode.

All of the symptoms and issues you mention could possibly be related to undiagnosed celiac disease, and vomiting is definitely fairly common as you can see by this search on Celiac.com:

https://www.celiac.com/search/?&q=vomiting&search_and_or=and

Feel free to scroll through the over 900 results there, and you will find some that sound remarkably similar to your son. Of course, other things could also cause this, but celiac disease would need to be eliminated. 

In children the best test to detect celiac disease would be the Deamidated Gliadin Antibody (AKA: DGP, DGP-AGA, DGP IgA and IgG) test, but a full blood panel should be done that includes this.

It's also possible that he has non-celiac gluten sensitivity (NCGS), and if so, there are not current tests for this. If all tests are negative you still may want to try a gluten-free diet for a couple of months to see if it offers relief to his symptoms.
