From my understanding, the upper GI is done the way Heather described it. (That’s also how we had it done.) The swallowing study (modified barium swallow) is done the way Ann Marie described it. The first is to look at structural abnormalities along the GI tract- probably just to make sure they didn’t miss anything. The second is done to look for feeding/swallowing problems including aspiration.
I’m not sure if Seth has had any testing done to this point, but given the prolonged nature of the symptoms, I would actually consider an endoscopy. He’s nearing three, when they would expect it to be gone already. The endoscopy would show if there was any damage (you can do it on or off meds), and if he has EE or other issues that don’t show up in an upper GI.
Our ped told us that we didn’t have to see the GI anymore (b/c the best advice he could offer us at that point was to try ranch salad dressing and see if that helped Hailey to eat), BUT that if she still had symptoms that required medication at age 3, then he wanted us to have another endoscopy, another metabolic workup, and allergy testing. I thought it was a good plan. I hate to go through everything again, but I actually believe that quite a lot of good information can be gained from the testing.
Good luck.
