Denise,
I also have a hiatial hernia. I have had it since my pre op days. About the only relief I found pre op was to try and eat small meals several times a day, take Pepcid (a perscription strength) and pre op I also ate ice cream when it got especially bad. I know post op there are limited choices on the Ice cream, but if you can get the Blue Bunny Brand they make one that is made with Splenda instead of sugar. It is very good.
Post Op, as long as I stay on the Pepcid I seem to do fine.
I hope this helps
Good Luck and I will keep you in my prayers.
Tami
