Why is my son having Projectile vomiting and constant burping

[kelster122]

My son who is only 17 has been suffering from projectile vomitting for 5 years and he's been constantly belching for 2 1/2 months.  He does have 4 ulcers.  He has had every test done and no one can tell us what is wrong with him.  He is currently on Carafate 1mg 4 x a day and previcid 20mg 2 x a day.  Celiac has been ruled out since his biopsy's from his endoscopy came back negative.  I've also been told by his doctors that he can't have an allergy to gluten since he does not have celiac.  I did take him off of gluten and the projectile vomitting did stop but now it's back.  Does anyone have an suggestions what could be wrong?  His doctors have given up on him.  I've been told there's nothing they can do for him.

That sounds like a good idea to get a second opinion.

He vomits when he was sneaking gluten in the beginning.  He has still been vomitting but not as bad since we did not know there was hidden gluten in the foods he was eating.  He has the ulcers because of all the vomitting he was doing before I took him off of gluten.  I am in the process of finding him a new gastro doctor and peditrician since both doctors have told me there is nothing else they can do for him.  

Thank you so much for responding.

Welcome to the gastroenterology community!  Did he start vomiting again when he started eating gluten again?  He may not have a gluten allergy but he may be sensitive to gluten.  If he feels better when not eating gluten, then don't let him eat gluten.  Also, in rare cases, the biopsy will be normal even though the person has celiac disease.  Have they figured out why he has ulcers?
