i may be wrong but H.Pylori is the bug that causes stomach ulcers. if i'm correct, hiatal hernia could be causing the acid reflux to backup and inflame an ulcer. i've had more ulcers than i can count. if it is. the H.Pylori is something that's always going to be in your stomach. my GI put me on Protonix 40mg twice a day. for ME, it works great.
Google the H.Pylori in the meantime. good luck hobbity, danny
