Hi my son is 18 years old and has been vomiting different times of the day for no reason for a year and half. Doctor said that my sons stomach was full and he only had a bowl of ice cream in 2 days. Doctors have had no idea so far until now when we finally after all this time get into the GI and first time just talking to my son and he said well you have a problem we were both like OMG finally. So the doctor said there is a blockage and not processing food. My son has been put on nexium, prilosec, and prozac to no prevail. SO I'm wondering if this sounds familiar to anybody. As a parent you can't wait to get answers.
