There is a surgery called pyloroplasty surgery, but you don’t want that sergery until is absolutly necesary b/c one problem get fix, but you may get another.
I have read that kids on PPI may have worst DGE b/c low stomach acids increases DGE b/c you need the acid to digets your food more efficently.
Many kids do outgrow DGE, Kendra has not been one of them. Her DGE right now is really bad due to a viral illness she recently had.
As long as you can keep under control with meds, things should be more managable.
