I investigated the fundi surgery years ago and found that all the patients I interviewed, still had to take the anti Gerd medications and did have repercussions from the surgery as well. Only less than 50% of those I talked to, had experienced a total remission of symptoms. No one I talked to, recommended it.
Having had GERD all my life due to an inherited Hiatal hernia, I suffered for years, slept sitting up (and still got GERD), avoided acid foods and more. Then I, by serendipity, discovered a cure for me. What happened is my hubby of many years, went to the hospital and I lost my appetite (he got a brain bleed from the daily aspirin he was taking ** sigh **
). I knew if I stopped eating completely, I would get sick so being a member of Weight Watchers online, I decided to force myself to eat what they said I should have, per day, about
1200 calories a day. My GERD went away. Completely! I still do avoid the acid causing foods, most of which one shouldn't have anyway, but haven't had any GERD at all since 2008, February. I ended up joining the classes (Weight Watchers) and became a lifetime member in Oct 2009. I had also lost 110 lbs and have kept this off since March 2010.
I avoid all fast food, junk food, high fat food etc. I don't know if this would help everyone (following the Weight Watchers program) but I think before one has invasive surgery, one might consider trying this if they haven't tried it. I don't think of myself as cured but rather in remission - but I do sleep lying down now. I think during 2010, I consumed ONE Tums all year - that's pretty good for a person who used to take so many TUMs I got a kidney stone! (in 1998). I also used to need a nightly alkaseltzer - the one time I had GERD in 2010, we didn't even have any alkaseltzer. I took one TUMS tab and was OK.
You can get a partial fundi which doesn't close off the stomach completely like a fundi does - the partial is very new and sounds like a better option. Hope this helps - if you have not tried the WW program, it might be worth a try. (and no, I don't work for WW)
