My son, who is 13, has been throwing up every
day for 5 months, with the exception of
few days. He's thrown up all but one day in 2014. He's had tests for: gall bladder, upper gi, endoscopy, MRI, ultrasound, giardia, thyroid, (he's gained weight), stomach emptying test, a poo cleanout, a variety of blood tests and urine tests, all of which have come back normal. Food does not seem to trigger it.
