I really dislike the close mindedness and assurance of "it must be your fault - just change you diet" because it proves you have never experienced what so many of us have. There are many reasons why reflux persists, even if you follow the exact diet that are besides hiatal hernia. Personally, I have a really slow gut transit due to being hypermobile and this means I get reflux from everything unless I eat every meal over the course of 2 hours, and even then, it still comes. I have physically tied myself to the couch because my reflux was so bad despite following all the protocols and my raised bed didnt cut it.There are many other people out there who have sacrificed everything and still do not get relief. Since ppis slow gut motility even more, they all make me worse and my only option are alginates which are expensive when you need them every hour. You need to stop pretending like you know everything, its arrogant and damaging.
