Hi. I was diagnosed with a hiatal hernia and acid reflux a year ago and been using esomeprazole for a year now. Even though I do not feel heartburn when I use the pill, I still feel the food coming up in my throat when I burp, this happens every day. After a meal, or a couple of beers, some of the food or drink comes back to my mouth with a burp and I can feel that food stays in my esophagus for a while before it goes down to my stomach and it comes back up with every burp. I want to know if this non-acidic reflux when im on ppi causes damage to my esophagus like acidic reflux does. Im really afraid of barrett's esophagus and do not want my reflux to cause it.
