from what i have read the PPI's do not have any effect on bile reflux. when your GI doctor performed and endo on you if you had bile in the stomach he would have seen this and put you on questran ( orange flavored resin powder , which is just awful to taste) to help clear up the bile in the stomach. if he hasn't told you that there is bile then you probably don't have it. have you had an esophagael manometry test? this will measure the strength of your esophagus muscles. i too have probablems swallowing, after fundoplication and later gall bladder removal. my last esophagael manometry test showed a parameter that measured 378 ( range is 500 -5000). prior to fundo i had measured 517. I have very weak esopagus muscles that can't push the food more effectively thru the stomach. thus longer residence time of ffod in my stomach gives me the sensation of heartburn, which is really esophagus sensation like burn. i have no barrett's because of the fundoplication. i was on antacis for 18 years and had no signs of all these bad things the doctors say about the antacids. take your omeprazole as he says and live your life as normal as possible. avoid caffeine, chocolates, carbonation , and cigarettes......best wishes ... kozlo52
