I have a 16 year old that has been vomiting almost every day since last August.
Initially symptoms started when he was working at a fast food place and was eating fast food. At that time vomiting was only when he ate fast food. His initial diagnosis was acid reflux, and was given prevacid.

He quit the job, but the stomach problems have increased. He is sick almost every day, usually in the middle of dinner is nauseous and feeling the need to throw up, or almost immediately after. As he eats you can see his face changing colors, as the nauseusness increases.

Endoscope on upper GI showed only scalloping of duodenum, biopsy showed mild damage, possibly early celiac

Swallow test was normal, (ie normal time is up to 2 hours to empty, his time was 1 hr 57 min)

Ultrasound of Gallbladder and liver, showed only few cholesterol crystal floating in gallbladder

At ER yesterday, complaining of sharp pains on left side, especially when standing. Xray done, no masses or strictures, but lots of stool matter, told maybe it was constipation and gave us a laxative.

Any ideas on what they need to do???
