Before my surgery in July 2008, I suffered from GERD and a hiatel hernia. Since my surgery I have been off Prilosec 100% because the issues were gone. About 4 weeks ago I got the stomach flu and had horrible vomiting, the first I have had since the surgery. My Dr did an upper GI on Fri and it didn't show anything, so he basically just removed the fluid from my band. I've regained almost all of my weight, and he tried to sell me on gastric bypass surgery, which I refuse to have done. I am having an upper GI on Wed. It's just hard for me to believe that the stomach flu, throwing up, and now having the acid reflux is not related.
